KIA Ceed is based on the Hyundai-Kia J5 platform. Since 2006, the model has been equipped with CVVT gasoline engines and diesel units with a common rail injection system. On the machines of the first generation, the most common were 4-cylinder gasoline engines of 1.4 liters and 1.6 liters with a capacity of 100 and 129 hp. with. respectively.

The 1.4-liter engine with factory marking G4FA, like the older “brother” - G4FC, has a chain drive. The cylinder block in both cases is made of aluminum, the only significant difference is the crankshaft and different piston stroke. The resource of KIA Sid G4FA and G4FC engines, according to the manufacturer, is at least 180 thousand km. In practice, these engines quietly go 250-300 thousand km.

The most powerful on the first generation KIA Sid was a two-liter gasoline engine with 2 liters. It is marked G4GC and produces 143 hp. with. power. The cylinder block is based on cast iron. And the resource of the unit, subject to normal maintenance and operation, exceeds 300 thousand km.

More rare in Russia is the KIA Sid with a 1.6 CRDi diesel engine. Its block is made of cast iron, and the turbine has a variable geometry. Power varies depending on the version within 122 liters. with. The main advantages of this engine are good throttle response and low consumption. But when refueling with low-grade diesel fuel, problems with the catalyst, particulate filter, and fuel system may begin.

The power units on the first generation KIA Ceed are paired with a five- or six-speed mechanics, a four-speed automatic. Reviews about the A4CF2 machine are mostly positive, the owners praise the adaptability of the transmission and smooth switching. The box is built on the basis of a reliable Japanese analogue F4A42. But with runs over 200 thousand km, breakdowns of the valve body and solenoids may occur. The problem is exacerbated by the untimely replacement of oil, which becomes contaminated and overheats, clogging the channels of the hydraulic plate.

As for the mechanics that KIA Sid was equipped with until 2012, it differs from the previously used boxes. There is a 3-axle gear train, and thanks to the cymbal synchronizer, it is possible to quickly and accurately select the desired gears. Various models of 5-speed manual transmissions are available (M5CF3, M5CF2, M5CF1), as well as the 6-speed M6CF2, which is based on a two-shaft scheme with synchronized gears.

Powertrains KIA Sid second generation

In 2012, the Korean auto company presented the second generation Kia Sid. The 1.4-liter G4FD and 1.6-liter G4FJ engines became available to customers. Their power is 130 and 204 hp. with. The most powerful G4FJ engine in the line is installed on the GT version. There is also a 1.6-liter GDI engine with a capacity of 135 horsepower, which works in conjunction with a 6-speed DCT robot.

The power units work in conjunction with a 6-speed mechanics or a 6-speed automatic A6GF1. This automatic transmission is quite reliable if you keep the oil clean and avoid overheating. In case of untimely maintenance, the hydraulic unit is the first to fail, namely the hydraulic plate.

When oil leaks, the solenoid valves wear out, and then the clutches. If you allow frequent slipping, drive the KIA Sid really aggressively, there are likely problems with the differential case, on which the splines are torn off. This is manifested by a characteristic crunch.

Weaknesses and in-place repair of KIA Ceed

Engines

The first problems with 1.4 and 1.6 liter KIA Sid engines may begin after 100 thousand km. So, with a run of 100-120 thousand km, the chain in the timing drive begins to stretch. If it is not changed, serious damage is possible. Crankshaft liners and piston rings survive up to 150-170 thousand km. In some cases, an incomprehensible vibration appears at idle, which is provoked by wear on the motor mounts or a software failure.

In diesel versions, which were not officially delivered to Russia, with solid runs, problems with the turbine appear. This is noticeable by the increased oil consumption, which takes up to 400 g per one thousand kilometers.

At the heart of the cylinder block, pistons of the G4FA, G4FC, G4FD, G4FJ engines is aluminum. The sleeves used are made of cast iron. The volume of oil in the lubrication system is 3.3 liters. To restore these power units, an additive is suitable. It will act in a complex way: it will clean aluminum surfaces from carbon deposits, contribute to their micro-grinding, and build up a layer of cermet on cast-iron sleeves. The use of RVS Master will eventually give the following results:

• Strengthening friction units.
• Compression normalization.
• Reduced fuel and oil consumption.
• Simplify cold start and minimize wear at this point.

To process a two-liter G4GC gasoline engine, a similar RVS Master Engine Ga4 additive will be required. But the result of its application will be even more noticeable, since the cylinder block is made of cast iron according to the old, time-tested technology.

If you are one of the owners of KIA Sid with a D4FB diesel engine, we recommend using an additive to extend the life and improve performance. This will extend the life of friction pairs, protecting them with a dense layer of cermet. But at high loads, these same friction pairs can partially come into contact due to the instability of the oil film. Thanks to the use of an additive for a 1.6 CRDi diesel engine, it will be possible to:

• Strengthen friction points.
• Normalize compression.
• Facilitate starting at sub-zero temperatures.
• Reduce fuel consumption by 7-15%.

​

transmissions

In the first generation KIA Sid mechanical transmission, the clutch, gears, and 3rd gear retaining ring are considered the weak point. With wear, the noise of the box increases, a crunch appears when shifting gears. The same A4CF2 machine is more reliable. It rarely causes problems with runs up to 200 thousand km. In the first batches of KIA Seed in the automatic transmission, there were breakdowns of the input shaft.

But the mechanical and automatic six-speed boxes on the second generation KIA Sid cause less complaints. Although there are still few copies with solid runs. To extend the life of manual transmission and automatic transmission, we recommend using oil additives. They form a dense layer of cermet on worn surfaces and reduce transmission noise. Suitable for a KIA Ceed machine, and for mechanics -.

Fuel system

Diesel versions of KIA Sid are sensitive to fuel quality. If you refuel with low-quality diesel fuel, the injectors, fuel pump, EGR valve are likely to become clogged. To prevent this from happening, add to the tank. The additive will increase the cetane index by 3–5 units, reduce the amount of deposits in the combustion chamber, minimize consumption, and facilitate start-up at sub-zero temperatures. After all, FuelEXx was developed specifically for the characteristics of Russian diesel fuel, taking into account the climatic features of the region.

For gasoline versions of KIA Sid, FuelEXx Gazoline is suitable. The additive increases the octane index of gasoline by 3–5 units, removes carbon deposits and varnish deposits from the walls of the combustion chamber, minimizes the wear of the CPG when refueling with fuel of dubious quality, and contributes to the decoking of piston rings. Also, the FuelEXx additive will remove water from the fuel, which will facilitate starting in the winter season.

When the first generation Kia Ceeds were new, they attracted motorists with their fresh European design, nimble engines and good prices. And now, after some time, you can judge how reliable these cars are and what you need to pay attention to when buying. KIA Sid with mileage.

Even though the Cee'd looks like a European car, its paintwork immediately betrays that it is an Asian car. It must be protected so that scratches and chips do not appear so often, because The paintwork of the Kia Sid is very delicate., and the varnish applied to the plastic peels off even better.

But the quality of the metal is quite good, the body does not immediately rust in those places where there is no paint. The only thing that can spoil the appearance of a car over time is corrosion that appears on the roof rails, as a rule, it appears after about 2 years, especially if the car is not in the garage. Further, the paint under the trunk lid may swell, and when choosing a used car, especially among the earliest models, you must definitely check the bottom of the doors and spring cups are the most vulnerable places for corrosion in Cee'd.

Vehicle interior

As in any car, Sid's electrics do not like dampness, if the contacts on the connectors oxidize, the immobilizer, wipers, electric lock for the tailgate may stop working, so you need to make sure that there is no oxidation on the wiring connectors. Basically, this applies to cars whose age exceeds 5 years. Such things can happen with an air conditioner - it happens that cold air stops flowing, in which case you need to check the condenser, its walls are quite thin, and for machines whose age is about 6 years, the lower honeycombs can rot to holes through which the refrigerant will exit to street.

Climate control is sometimes a hassle too, especially if the electric dampers break down, each of which will cost $ 20. For those owners who bought cars at dealerships, they immediately changed the control unit under warranty. It also happens that over time, the cabin temperature sensor fails and the display shows + 60 ° C overboard, but this is not a cause for concern - quite simply clean the external temperature sensor from dirt installed behind the front bumper.

Sufficiently delicate windshields were installed on pre-styling cars, there were times when cracks appeared on them during frost, fortunately, they could be replaced under warranty. And due to the fact that the windshield washer sprays weakly, and belatedly - the brushes are already waving, and the liquid is just starting to flow - the glass is rubbed faster. After restyling in 2009, the washer pump was finalized and as a result, the glass became less rubbed.

Power units for Kia Sid

Kia Cee'd is equipped with Gamma gasoline engines, the volume of which is 1.6 liters and 1.4-liter engines. Most, about 73% of cars on the market are equipped with 1.6-liter gasoline engines, about 13% of cars - with 1.4-liter engines. But these power units are not super-reliable, so they must be carefully checked when buying. Already after 50,000 km. run, floating idle appears, which means throttle body needs cleaning. Low-quality oil and dust entering the intake tract can cause scuffing on the coating of the aluminum cylinder block.

There are frequent cases that already by 150,000 km. mileage will have to change the piston rings, the price of which is approximately $ 40, the connecting rod and main bearings will also require replacement, such a kit will cost $ 90. Of course, you need to refuel with good gasoline so that you do not have to spend money on a new converter, which is not cheap for Sid - $ 1,000.

If after 100,000 km. dips appear during acceleration, this means that already stretched timing chain which costs about $40. There is also an unreliable tensioner, it costs only $ 30, but because of it you can get into the money, if the chain jumps a few teeth, then the pistons will meet the valves, which will eventually lead to an overhaul of the engine.

Such a fact is noticed that these motors are prone to oil leaks. The front timing cover and valve cover are often covered in oil. The thing is that sealant is used instead of conventional gaskets, and the sealant loses its properties after 5 years. The rear crankshaft oil seal also does not withstand oil pressure over time, so it flows out through it. And if you notice that antifreeze level started to drop and the car leaves white marks behind it, which means it's time to change the cylinder head gasket, fortunately it only costs $20. Antifreeze can start to flow out like this no earlier than after 130,000 km. run.

There is also an interesting feature of Seeds with gasoline engines - a fuel tank that makes interesting sounds similar to pops. The fact is that after 3-4 years the filler plug valve sticks and the absorber has already worked out, its replacement will cost $ 30. So these two parts in a steel tank create a strong vacuum, pops will appear, and if you ignore them, then after a while the gas tank may burst, and this is very unpleasant, especially if there is a considerable amount of gasoline left. The price of a new tank does not exceed $ 500, so you need to watch for unusual sounds and quickly make the right decision to fix the problem.

Diesel engines

Least of all cars with turbodiesels under the hood were produced: 3% of cars with a 1.6-liter engine and 1% of cars with a 2-liter engine. It cannot be said that diesel engines are more reliable than gasoline ones. In most cases, injectors will easily last 150,000 km, and replacing them will require about $ 290 from your wallet. With regards to the Bosch injection pump, there are 250,000 km. won't create any problems. But there were times when Garrett turbochargers had to be changed after 100,000 km. mileage, and their price is rather big - 670 dollars.

But these are all trifles compared to what happens to pistons after 100,000 km. run, - cracks appear on them, and the cylinder block cast from cast iron is also seriously worn out. The price of such a block is about 1100 dollars. But now there is no need to change it - there are specialists who can restore the cylinder block by inserting repair sleeves there, like on a Zhiguli. It is also important to notice dips and jerks at about 2000 rpm, which means that boost pressure sensor gone, which is priced at $25. But if the engine does not start, then you can check the fuel pressure sensor, it could fail, its price does not exceed $ 250.

And the best option for KIA Sid is considered to be a 2-liter gasoline engine from the Beta series. This is a good old motor, created in 1997 and modified in 2002. It uses a cast-iron cylinder block, a timing belt. Such a motor can easily withstand 250,000 km. and more. The only thing that can cause problems is the ignition coils, which can burn out after 40,000 km. There are also glitches at the coolant temperature sensor, so the engine can overheat when driving in traffic jams.

Transmission

In the case of KIA Sid, it is better to choose an automatic than a mechanic. Together with a 1.6-liter engine, an automatic transmission quietly serves at least 250,000 km, if you change the oil every 70,000. The box is not particularly agile, because there are 4 steps, but due to the fact that the design is simple, it is reliable. Sometimes it happens that after 150,000 km. mileage there are shocks when switching, this is due to the torque converter lock-up solenoids or valve body valves, but this rarely happens.

As for the mechanical box, there are continuous problems here: gears, synchronizer clutches, gear rims wear out quickly. Already after 140,000 km. the box starts to crackle and gears are hard to insert. And you need to change the clutch disc even earlier. The release bearing costs about $ 20, and the clutch disc costs 70 US rubles.

Suspension

You also need to monitor the anthers of the CV joints, after 50,000 km. grease may leak from them. For $70, you can buy a set of rubber bands that will ultimately save you about $450, which is how much the axle shaft together with both pivots will cost.
In general, the KIA Seed suspension is also considered not very reliable. After 60000 km. mileage usually has to change shock absorbers, for Sid - from Mando, the front ones cost $ 120, and the rear ones 160. Also, along with the shock absorbers, it is customary to change the wheel bearings, the front ones can be bought separately, but the rear ones come with the hub, it turns out more expensive.

On early models, the rear shock absorbers made a rumble during operation, these shock absorbers were changed under warranty, but after 20,000 km they started to rumble again. Already in 2009, during restyling, the shock absorbers were finalized and the roar passed. Consumables are front stabilizer struts, where the lower hinge is poorly sealed. These struts cost $12 each, but sometimes they don't last even 20,000 km. run.

The brakes in the car are quite reliable, especially if you lubricate the caliper guides every 2 years. The discs themselves can easily withstand about 70,000 km. If during braking the car begins to wear to the sides, then be sure to need to check silent blocks front suspension arms, if they are worn out, then the car will wag when braking, these silent blocks cost $ 7. But the silent blocks on the rear suspension age without any special signs, after about 80 thousand km. they need to be changed.

The electric power steering is usually not a problem. There were cases that on cars older than 2009, unsuccessful gears came across, which caused knocking after 60 thousand km. run. The steering gear is $970, so it's good to have it replaced under warranty. Therefore, when buying a used car, you need to check whether there are knocks and other rattling while turning the wheel. But in most cases, tie rods, which cost $12 apiece, can be the cause of the knock.

As for its money, Sid is a normal car, it does not differ in particular reliability, and where can you find a non-breaking car now. Cee'd's advantages are that it is cheaper than competitors in the class (Volkswagen Golf and Toyota Auris) by about 100,000 rubles, but the Peugeot 308 and Opel Astra cost the same as Sid. And there is such a car as the Ford Focus, so it costs less, and even lasts longer, it is more reliable in general.

But for those who want buy KIA Sid- it is best to choose a model after restyling, younger than 2009, with a 2-liter engine and an automatic transmission. With this configuration, problems will be the least.

Crash test results

In the famous Euro NCAP crash test, the Cee'd hatchback participated and scored a very high score: 34 out of 36 possible. Even though the clutch pedal moved 100mm during the frontal impact, this did not stop the car from getting a high score. The car also passed the side crash tests with the maximum score. Protection for child passengers is also quite good - 4 out of 5. But safety for pedestrians is extremely low - 2 out of 5. And all because the front bumper of the Kia Sid is extremely traumatic, so if you are walking at a pedestrian crossing and see this car, then run away from her.

This video will help to structure the knowledge obtained from this article about possible malfunctions of the KIA CEED car until 2012 and skillfully apply them in practice. We look:

The range of engines is represented by three petrol models with a working volume of 1.4, 1.6 and 2 liters, as well as two diesel models: 1.6 and 2 liters. Let me take a closer look at each of them:

Petrol 1.4 and 1.6 (Gamma)

We will consider these engines in pairs, as they are distinguished only by the displacement and VSH (external speed characteristic). The power unit is an in-line four with two overhead camshafts (DOHC). I would also like to note that the CVVT system of constantly variable valve timing works on the engines. Of the undoubted advantages, the following points can be distinguished:

The engine is a completely new development, namely:

Modernized crank mechanism.

Aluminum cylinder block.

Reduced weight and friction.

Optimized intake and exhaust manifolds.

Low fuel consumption and CO2 emissions.

Gasoline 2.0l (Beta)

This engine has gained confidence with its unpretentiousness to fuel quality, simplicity and reliability of the time-tested design. Here the same layout is used as on the engines of the Gamma series - 4 cylinders in a row and 16 valves (2 camshafts) with a system of constantly variable valve timing CVVT. The advantages of this power unit are:

Low noise level.

Changed piston shape, graphite coating.

Optimized cavity resonator.

Diesel 1.6l.(U-V.G.T)

The diesel engine is the latest development of the Kia concern and is equipped with an advanced second-generation Common Rail fuel injection system. The undeniable advantage of such a system is the ability to individually control the injection advance and the amount of injected fuel for each cylinder, which reduces fuel consumption, noise, and increases acceleration dynamics and engine elasticity. Summarizing the advantages of this unit, we have:

Flat torque curve at high engine speeds.

Excellent fuel efficiency and low CO2 emissions

Diesel 2.0l.(D-V.G.T)

The 2.0-litre diesel is also equipped with a second-generation Common Rail fuel injection system (operating pressure 1,600 bar). One of the few differences between the two-liter diesel and its little brother is the presence of a single overhead camshaft (SOHC). The pros are as follows:

Second generation Bosch Common Rail fuel injection system (pressure 1,600 bar)

32-bit Electronic Engine Control Unit (ECU)

Electronic control of the EGR valve and cooling.

Intake air flow control system.

Answers to frequently asked questions (FAQ)

What kind of oil is poured from the factory into KIA cars?

For gasoline engines: Shell 5W-30 or HK GLF 5W-20
For diesel engines: HK LS 5W-30 or HK SD5W-30

How many liters of gasoline are left in the tank when the red light on the dash lights up?

As soon as the computer shows that there are less than 50 km left to drive, i.e. dashes will flash - you can safely pay for 45 liters, in fact, there will still be 6-8 liters left in the tank. Naturally, you can drive more than 50 km. Apparently this reserve (2 liters) is designed for the unexpected. Convinced by experience.

However, taking into account that the gasoline pump is submersible and is cooled by the gasoline in the tank, driving “on a light bulb” all the time is highly undesirable, especially in the heat.

What kind of oil filter do we have?

For KIA CEED and KIA CEED FL (2007-2011) dorestyle and restyling

For a 1.4, 1.6 liter gasoline engine: engine oil filter - No. 26300-35503, as well as 26300-35501 and 26300-35502;

For a 1.6 liter diesel engine: engine oil filter - No. 263202A500, as well as 26320-2A002 and 26320-2A001;

For a 2.0 liter diesel engine: engine oil filter - No. 2632027401 and 2632027400.

For KIA CEED 2012 second generation

For gasoline engine 1.4, 1.6 liters: engine oil filter - No. 26300-35530

Sometimes reverse gear does not turn on on a manual gearbox

When the clutch is released, instead of driving, a characteristic screech is heard from the box - this is a problem in the “non-engagement”

This is due to the fact that the reverse gear does not have a shaft synchronizer.

The following solutions have been found:

Engage reverse gear after a complete stop of the car, if the gear is not engaged, shift the gearshift knob to the “neutral” position and after waiting about 3 seconds, repeat the gear shift.

Engage reverse gear as usual and then very smoothly bring the clutch to the moment where it “usually grabs” and push the gear lever further without effort. You should feel how the transmission is switched on.

When you lift the gearshift knob up, at the end you need to apply some effort. You can even feel whether the speed has turned on or not - when you turn it on correctly, you feel such a click (gear engagement). If not, the lever back a little and up again.

What fuel pressure does the fuel pump pump on a 1.6L gasoline engine?

338-348kpa(3.45-3.55kgf/cm2)(49.0-50.5psi)

What fluid to fill in automatic transmission?

Gear oil meeting the SPIII specification from the following manufacturers: Mitsubishi (Diamond, DiaQueen), BP Autran, Chevron, Ravenol.

What spark plugs are on our engines? And how to change them?

For gasoline 1.4, 1.6 liters: NGK ZFR5F-11. Thread diameter 14mm, thread pitch 1.25. Since 2009, a modified block head can be installed on 1.6l (G4FC) engines! It uses candles with a long skirt 26.5 and a diameter of 12mm -.

For gasoline 2.0 liters: NGK BKR5E-11 (1881411051).

Replacement procedure for gasoline: remove the top cover, there is a coil on each candle, a bolt (10) on each coil, unscrew all 4 bolts and simultaneously remove 4 coils.

Do the engines have hydraulic lifters?

Hydro compensators are only on diesel engines with a volume of 1.6 and 2.0 liters.

How are valves adjusted on gasoline engines and when?

The valves are adjusted as necessary, after checking, at a mileage of 75,000 km and 150,000 km. For 1.4 and 1.6 liters - cups, for 2.0 - washers.

Cars produced by the South Korean company KIA Motors Corporation (1944) feel quite confident in the domestic car market. Their popularity is largely due to the reliability and unpretentiousness of the G4FC and G4GC engines, the mass production of which is mastered at factories located in China and Korea, respectively.

Description

The G4FC and G4GC engines, although they belong to different families (Gamma and Beta, respectively), are made according to the same scheme and are identical in design. Both motors are classic 4-cylinder power units with a four-stroke mode of operation.

In their designation, the first letter indicates the type of fuel (Gassoline). The number following it indicates the number of cylinders. The third letter, in this case F and G, indicates that the motor belongs to the Gamma and Beta families, respectively. The last letter (C) determines the volume of the power unit in accordance with the manufacturer's model line: Gamma - 1.6 l; Beta - 2 l.

Despite the fact that the cylinder blocks (BC) of these power units are made of different materials, the heads (cylinder head) of both are made of aluminum alloy. They are equipped with a 16-valve gas distribution mechanism (timing) with two DOHC 16V overhead camshafts, equipped with a CVVT (Continuous Variable Valve Timing) phase change system. It is located on the intake shaft, which is connected to the exhaust chain.

In addition, both motors do not have hydraulic valve compensators and therefore require regular (every 90 - 100 thousand kilometers) clearance adjustment.

Lubrication systems and KIA are identical to each other.

Distinctive features of power units:

• G4FC engine

The G4FC power unit is equipped with a timing belt, the drive of which is driven by a chain that does not require maintenance during the entire period of operation. In the latest modifications of the motor (Gamma II family), the CVVT system is installed on both timing shafts. These power units are capable of developing power up to 130 hp. with. You can also find versions of KIA engines with direct fuel injection (GDI) and turbocharging (T-GDI).

• G4GC engine

The timing of the G4GC engine is driven by a belt drive. The belt must be changed after every 60 thousand km. the distance traveled, which will avoid its breakage and related troubles (bent valves, etc.).

Maintenance

G4GC and G4FC engines are distinguished by their unpretentiousness in operation.

If you do not take into account the need to replace the timing belt (only in G4GC engines) and regularly adjust the timing valve clearances, maintenance of KIA engines is reduced to the periodic replacement of consumables (engine oil and coolant).

ATTENTION! The mechanism for dynamically changing the position of the intake camshaft and the solenoid valve included in the CVVT phase change system of the engines of KIA Rio and others (including G4GC) are high-precision components. In this regard, their replacement is carried out only in the collection.

• in G4GC and G4FC engines

The G4GC engine, like the G4FC engine, requires an engine oil change no later than 15,000 km. At the same time, the manufacturer recommends that when operating power units in difficult conditions, perform this procedure after 7,500 km of the distance traveled.

The process of replacing engine oil is carried out on a hot engine, and at the same time as the oil, it is necessary to replace the oil, fuel and air filters.

The volume of oil poured into the G4FC engine is 3.3 l; engine G4GC - 4 l.

• Replacing the coolant in the engine of a KIA Sid car, etc.

The main signs confirming the need to replace the coolant are the red color of antifreeze, an oily film on its surface, and other deviations from its original appearance.

The manufacturer recommends using Hyundai / KIA 07100 - 00200 antifreeze as a coolant. It is a high quality coolant that is manufactured according to the specifications of the power unit manufacturer in many countries (including Russia) and has the appropriate Hyundai Motors approval.

The replacement of antifreeze in KIA cars is carried out on cold engines. After completing the procedure, the engine must be warmed up to operating temperature, then make sure there are no air pockets and check the level of antifreeze in the expansion tank.

Coolant volume to be filled in:

1. motor G4GC - 6.7 ... 6.8 l;
2. G4FC engine - 5.5 ... 5.8 liters.

IMPORTANT: if a few days after the start of operation, the new liquid has changed its color to brown or completely discolored, then a fake was purchased. Such "antifreeze" must be urgently replaced.

Faults

Considering the shortcomings that the KIA Rio engine (Gamma family) has, one cannot fail to note their similarity with the malfunctions of the power units of the Beta family (KIA Spectra engine, etc.). This is due to the fact that the top-end G4FC engine of the Gamma family is structurally identical to the flagship of the Beta II engine line - G4GC.

Typical defects of these power units begin to annoy drivers from the first days of operation and are eliminated in the same ways.

The KIA Sid engine can serve as an example of eliminating such defects, since engines of both families are installed on these cars.

FAULTS	CAUSES	SOLUTIONS
Unstable operation of the motor at idle and in the "acceleration-braking" modes	1. Faulty ignition coil. 2. Breakdown of high-voltage wires. 3. Defective spark plugs	In all cases, it is necessary to replace defective components.
"Hang" engine speed.	Factory defect in the firmware of the electronic control unit (ECU) of the engine.	ECU flashing. It is recommended to carry out at certified service stations
Vibration of the engine at idle.	Spark plugs or throttle body dirty.	Clean parts from contamination.
Knock in the engine.	1. Timing chain rattles. 2. Valve clearances in the timing are not adjusted.	Ÿ After the engine warms up to operating temperature, the timing chain stops making noise. Adjust valve clearances. This operation is best done at the service station.
Whistling during the operation of the power unit.	Weak alternator belt tension.	Replace belt tensioner pulley.
The engine speed fluctuates.	Dirty throttle body or spark plugs.	Cleaning parts from contamination.

Tuning engines KIA (G4GC and G4FC)

There are several ways to increase the power of the G4GC power unit:

1. Calibration (flashing the ECU) of the engine. At the same time, experts promise an increase in power up to 150 hp. with.
2. In order to raise the power of the G4GC engine to 160 hp. with. it is necessary to perform a number of improvements: to introduce a direct-flow exhaust by installing a "spider" 4-2-1; install camshafts with a phase of 268/264 and a large valve lift.
3. In addition, you can try to increase the power of the G4GC motors to 180 hp. with. However, this requires specially made to order camshafts with a phase of 270 and a large valve lift. In addition, it is necessary to weld the original turbo manifold and provide oil supply to the TD04L turbine. You will also need an intercooler, piping, 440 cc injectors, an exhaust pipe with a diameter of 51 or 63 mm. Put together, such a system, when properly configured, is capable of delivering up to 180 hp to the G4GC. with. However, how long his resource will last is unknown.

The G4FC engine is also tuneable:

• Raise its power to 160 liters. with. it is possible by installing a compressor RK-23-1 (RK-23-e) and a small turbine.

In addition, you need:

1. install the exhaust on a pipe with a diameter of 51 mm;
2. bore the inlet and outlet channels of the timing;
3. use large valves.

In addition, in order to preserve the resource of the KIA Rio engine, it is imperative to put a forged piston group under a compression ratio of 8.5. If this is not done, then the engine, designed for a compression ratio of 11, will simply fall apart.

Kia Cee "d cars are equipped with transversely mounted four-cylinder four-stroke gasoline injection 16-valve engines with a displacement of 1.4; 1.6 and 2.0 liters of mod G4FA, G4FB and G4FC, respectively, as well as four-cylinder diesel engines with a displacement of 1.6 and 2 .0 l mod D4FB and D4EA.

All engines - with in-line vertical arrangement of cylinders, liquid cooling, Details and assemblies are shown on the example of the engine G4FB(Fig. 5.1 and 5.2).

Engine camshafts are driven by a chain

cylinder head engines are made of aluminum alloy according to the transverse cylinder scavenging scheme (inlet and outlet channels are located on opposite sides of the head). Seats and valve guides are pressed into the heads.

Engine block i is a single casting of a special light aluminum alloy, forming the cylinders, the cooling jacket, the upper part of the crankcase and five crankshaft bearings. Thin-walled cast-iron liners are installed in the cylinder block. In the lower part of the block, there are five beds of main bearings, processed as an assembly with the block and non-interchangeable. On the cylinder block, special lugs, flanges and holes for fastening parts, assemblies and assemblies, as well as channels of the main oil line are made.

Crankshaft rotates in main bearings having thin-walled steel liners with an antifriction layer. The crankshaft of the engine is fixed from axial movements by two half rings installed in the grooves of the bed of the middle main bearing.

Flywheel cast iron, mounted on the rear end of the crankshaft through the mounting sleeve and secured with six bolts through the washer. A gear rim is pressed onto the flywheel to start the engine with a starter.

Since the flywheel is made rather thin, a spacer washer serves to reinforce it, and nuts are welded on the rear surface of the flywheel for this purpose instead of threaded holes for fastening the clutch pressure plate casing. On automobiles with an automatic transmission, instead of a flywheel, a torque converter drive disc is installed.

Pistons made of aluminum alloy. On the cylindrical surface of the piston head, annular grooves are made for the oil scraper and two compression rings. The pistons are additionally cooled by oil supplied through the hole in the upper head of the connecting rod and sprayed onto the piston crown.

piston pins installed in the piston bosses with a gap and pressed with an interference fit into the upper heads of the connecting rods, which are connected with their lower heads to the connecting rod journals of the crankshaft through thin-walled liners, the design of which is similar to the main ones.

connecting rods steel, forged, with an I-section rod.

Lubrication system combined.

Ventilation system The crankcase of a closed type does not communicate directly with the atmosphere, therefore, simultaneously with the exhaust of gases, a vacuum is formed in the crankcase under all engine operating modes, which increases the reliability of various engine seals and reduces the emission of toxic substances into the atmosphere.

The system consists of two branches, large and small.

When the engine is idling and in low load modes, when the vacuum in the downpipe is high, crankcase gases are sucked in by the intake pipe through the crankcase ventilation valve installed on the cylinder head cover. The valve opens depending on the vacuum in the intake pipe and thus regulates the flow of carger gases.

In full load modes, when the throttle is open at a large angle, the vacuum in the intake pipe decreases, and crankcase gases increase in the air supply hose through the large branch hose connected to the fitting on the head cover, mainly enter the air supply hose, and then through the throttle assembly into the intake pipe and into the engine cylinders.

Cooling system the engine is sealed, with an expansion tank, consists of a cooling jacket made in casting and surrounding the cylinders in the block, combustion chambers and gas channels in the cylinder head. Forced circulation of the coolant is provided by a centrifugal water pump driven by a crankshaft poly V-belt, which simultaneously drives the generator. To maintain the normal operating temperature of the coolant, a thermostat is installed in the cooling system, which closes a large circle of the system when the engine is cold and the coolant temperature is low.

Supply system The engine consists of an electric fuel pump installed in the fuel tank, a throttle assembly, a fine fuel filter located in the fuel pump module, a fuel pressure regulator, injectors and fuel lines, and also includes an air filter.

Ignition system i engine microprocessor, consists of coils and spark plugs. The ignition coils are controlled by the electronic unit (controller) of the engine control system. The ignition system during operation does not require maintenance and adjustment.

power unit(engine with gearbox, clutch and final drive) is mounted on four supports with elastic rubber elements of the two upper side (right and left), perceiving the main mass of the power unit, and the rear and front lower ones, compensating the torque from the transmission and the loads that occur during starting the car from the place of acceleration and deceleration.
