Lifan Solano according to the Chinese catalog Lifan 620, budget sedan for relatively little money. Lifan Solano almost exact copy 120 Corollas. Solano borrowed almost everything from the Corolla: suspension, engine, gearbox, interior elements.
Engine Lifan Solano This is an exact copy of the 1.6 4A-FE engine, only slightly modified, at least instead of ignition wires they put coils on each spark plug. The engine consumes 92 gasoline, and the car’s tank is 60 liters; by the way, consumption does not exceed 10 liters in the city.
Motor 4A unique, it lasts up to 500 thousand km without a major overhaul, and after a major overhaul, the timing belt is the same; if a valve breaks, it doesn’t bend, and replacing it is mere pennies compared to a chain, only 4 thousand rubles, and takes 3-4 hours . On Chinese engine spark plugs and wires, as well as the timing belt and rollers can be replaced with European analogues, spark plugs can be supplied with DENSO K16R-U11 so that the engine runs without interruption, the coils also need to be replaced with European analogues. It is better to change the belt at 60 thousand km, the bearings can be taken from Koyo, and the timing belts and auxiliary units SUN.
It’s better to change it at 60 thousand km, you can take Koyo bearings and SUN timing belts and auxiliary units.
Box Lifan Solano only 5-speed manual, since 2014 a CVT has been installed, but these cars are rare in the secondary market. Release bearing It may fail after 30 thousand km, they are replaced under warranty, if the replacement is independent, then it is better to replace it with a non-original one. Repairing the box is cheap and can cost no more than 7 thousand rubles, and spare parts are plentiful.
Lifan Solano pendant, also simple, but it will start knocking already at 15 thousand km, the stabilizer struts will be the first to fail, replacing them costs about 400 rubles per piece, then the balls and struts, it is better to change them immediately to branded models, do not chase the original.
If the air conditioner stops cooling, then most likely the tube that goes to the radiator has broken off; a replacement at a service center costs 3,000 rubles.
Lifan Solano Good car, with cheap spare parts, for example, an original oil filter costs 50 rubles, a spark plug costs 60 rubles, an air vent costs 100 rubles, spare parts for the suspension are generally pennies, but it’s better to install not the original, but branded manufacturers such as Koyo, gates, sun, 555, crt and other. There is no noise in Solano, but this is also not a problem, the car is glued in 1 day and 5 thousand rubles.
Lifan Solano can be repaired independently; suspension and component parts are easily accessible.
Problem Lifan Solano only one is a very thin metal, so be careful, any small impact can lead to dire consequences.
Lifan Solano is not of interest to car thieves, only to children, so the car can get by with a cheap alarm.
Engine characteristics of Lifan Solano
The Solano is equipped with a Chinese LF481Q3. This is an analogue of the Toyota 4A-FE engine with minor changes. In particular, the ignition distributor was removed and an electronic ignition module was installed. But the fact that the engine is Chinese does not mean that it is somehow bad. The engine is good, lasts a long time and works well, although I have not yet seen a car with a mileage of more than 130 thousand km.
Some Typical Parameters LF481Q3:
Cylinder diameter: 81 mm
Stroke: 77 mm
Compression ratio: 9.5:1
Fuel: 93 unleaded gasoline
Rated speed: rpm 6000
Rated power: kW 78
Max Torque: Nm/RMP 137Nm/3500rmp
Minimum speed idle move, rpm 800 ± 50
Idle emission limit CO ≤ 0.3%, CH ≤ 80ppm
Ignition timing (idle) 5 ± 3 º
Intake valve clearance (cold) mm 0.20 ~ 0.25
Exhaust valve clearance (cold) 0.30~0.35
The Lifan Solano LF481Q3 engine has 16 valves and two (2) camshafts. There are no hydraulic compensators at all; the valves are driven by pushers-cups, and adjustment is carried out by selecting the thickness of these pushers.
The timing drive on this engine is a belt, and if this belt breaks, there is a 98% chance that the valves will not bend... We have verified that we have already encountered two cars with a broken belt.
Camshaft graduation valves are driven timing belt, and the shaft intake valves It is driven by skewed gears, which are mounted on shafts.
The injection system on the Lifan is multi-point, which means that injection into the cylinders occurs only when this particular cylinder is on the intake stroke. At this moment, gasoline is not injected into the remaining cylinders.
The control unit takes the parameters of many sensors located on the engine and, based on their readings, controls mixture injection, achieving optimal engine operation in all modes.
The electronic control system consists of the following three parts:
(1) Sensors - Convert various non-electrical parameters into electrical parameters that the ECU can understand.
Sensors include: Sensor .
① Inlet pressure/temperature, measures air pressure and temperature during intake manifold. Based on these readings, the ECU calculates the amount of gasoline injected at each time. 
②Throttle Position Sensor,“shows” to the control unit how much the gas pedal is pressed. Accordingly, the unit increases fuel injection for acceleration or decreases for deceleration. The response speed of the control unit depends on the engine control program installed in it.
③ Coolant temperature sensor, by coolant temperature fluid The ECU also regulates the fuel injection time and its composition, enriching it for a cold start.
④ Heated oxygen sensor
, Monitors the oxygen content in the exhaust. Based on this data, the ECU determines whether it is rich or lean mixture now enters the cylinders and adjusts its composition to the ideal (14.7 parts of air to 1 part of gasoline).
⑤Knock sensor, works in tandem with a rough road sensor. Able to easily determine and transmit to the ECU data about which cylinder is not working (no spark, for example, or no fuel)
⑥ Position sensor crankshaft
, the main sensor, by which the unit determines what cycle is occurring on this moment in each cylinder.
(2) The electronic unit management(ECU) is the "brains" for everything electronic system control, which analyzes and processes all information from sensors, sends orders to control mechanisms, and adjusts engine operation under a variety of conditions.
(3)Actuators execute commands from the control unit
① pump supplies fuel under pressure to the ramp.
② injectors, inject it into the cylinders.
③ ignition coil, creates high voltage to create a spark.
④ Рхх, idle air control, opens the bypass channel in throttle valve to supply air when it is completely closed (at idle).

The timing drive on this engine is a belt, and if this belt breaks, there is a 98% chance that the valves will not bend... We have checked that we have already encountered two cars with a broken belt.
Camshaft graduation The valves are driven by the timing belt, and the intake valve shaft is driven by slanted gears that are mounted on the shafts.
The injection system on the Lifan is multi-point, which means that injection into the cylinders occurs only when this particular cylinder is on the intake stroke. At this moment, gasoline is not injected into the remaining cylinders.
The control unit takes the parameters of many sensors located on the engine and, based on their readings, controls mixture injection, achieving optimal engine operation in all modes.
The electronic control system consists of the following three parts:
(1) Sensors- Convert various non-electrical parameters into electrical ones that can be understood by the ECU.

(3)Actuators execute commands from the control unit

② injectors, inject it into the cylinders.
③ Ignition coil, creates high voltage to create a spark.
④ Рхх, idle air control, opens the bypass channel in the throttle valve to supply air when it is completely closed (at idle).
The Lifan Solano engine is short-stroke (the piston stroke is less than the cylinder diameter), and short-stroke engines produce more power at high speed. This means that this car will only “rip” at high speeds.
Do valves bend on Solano 1.6?
Yes, the valve can bend if the timing belt breaks. The consequences of bent valves can be very diverse, from cylinder head repair, before overhaul motor or replacement.
Adjusting the gaps
Valve adjustment Solano 1.6
The valves are adjusted using adjusting washers and cups. The normal gap between the exhaust valve and the r/shaft cam should be 0.25-0.35, and the intake - 0.15-0.25 mm. If the gap is increased, you need to select the desired adjusting washer and place it under the pusher. The process of preparing for measurement is quite simple. Filming valve cover, having previously dismantled the associated units. We take out the spark plug channels and make adjustments. If the cams are on camshaft has been demolished, it needs to be replaced.
Incorrect clearances in the valve mechanism can lead to deterioration in car dynamics, “shots” in the muffler, knocking in the engine and other unpleasant consequences.
The adjustment is checked on a cold engine by measuring the gap between the valve tappet and the camshaft cam. Normal clearance for exhaust valve should be in the range of 0.25–0.35 mm, and for the intake – 0.15–0.25. The check is performed with a feeler gauge with the camshaft cam pointing upward. If the gap values do not correspond, then we adjust the valve by selecting a pusher of the required thickness. The formula used for this is:
Н=В+А-С, where Н is the thickness of the new pusher, A is the gap value, B is the thickness of the old pusher and C is the normal gap value.
Checking and adjusting the gap in Lifan valves X60
— Remove the main covers of the intake camshaft.
— Supporting drive chain Remove the intake camshaft by hand as shown in the figure.
— Secure the timing chain with a rope, as shown in the figure.
— Remove the valve tappet.
— Measure the thickness of the removed valve tappet with a micrometer.
— Calculate the thickness of the new valve tappet (see table below) so that the valve clearance is within the specified range.
Valve clearance calculation:
Inlet valve:
A = B + (C - 0.22 mm)

Checking and adjusting the valve clearance of Lifan X60
Valve adjustment on 1zz-FE
Due to the fact that valve adjustment on Emgrand and Lifan X60 engines is performed mechanically, sooner or later the need for such adjustment may arise. This article is written for those specialists who decide to take such a step. All data is taken from official sources (www.geely.com).
I will not describe in detail some, in my opinion, obvious points, such as removing the valve covers.
Adjusting the valves on the Gili Emgrand engine (aka the engine from Lifan X60)
To start remove the plastic engine cover, I hope there won't be any problems with this. You also need to remove the ignition coils, otherwise it will be difficult to remove the cylinder head cover.
Disconnect the high-voltage wires from the coils and unscrew the mounting bolts.
Remove the coils from the spark plugs.
Remove the cylinder head cover.
To do this, first disconnect the terminals from the battery, as all textbooks teach.
Remove the two ventilation hoses from the cylinder head cover.
Unscrew the bolts and nuts securing the cover and remove it.
Remove the timing chain cover
A separate article on removing the timing cover on Emgrand and X60 engines (analogous to Toyota's 1ZZ-FE).
Remove the timing chain and rotate the crankshaft so that the piston in the first cylinder is at top dead center.
Check the clearances in the valve drive shown in the figure
Write down the valve number and the size of the gap, if it does not meet the permissible limits.
After this, you can move on to the remaining valves. To adjust them, you need to rotate the crankshaft 360° (one revolution). Thus, the top dead center of the compression stroke will be in the 4th cylinder.
Measure the gaps in the valves indicated by arrows and write down the gap sizes.
Removing valve tappets to replace them
To remove the pushers, support the engine with a jack and remove the timing chain.
Remove the desired camshaft l, remove the pusher that needs to be replaced. Measure its thickness with a micrometer and calculate the thickness of the new pusher using the following formula:
Inlet: A=B+C-0.23 mm. (0.01 inch)
Issue: A=B+C-0.32 mm. (0.32 inch)
A- thickness of the new pusher; IN- thickness of the old pusher: WITH- measured gap
Select and install the desired pusher.
Everything is put together in reverse order.

A common problem for owners of cars that have engines with a timing belt drive is that if the belt breaks timing belt On such cars the valves bend. Why does this happen, which cars have such problems and how to avoid internal combustion engine repairs.
Why does the valve bend when the timing belt breaks?
You're driving along in your wonderful car, and suddenly there's a knock and the car stops. This is how the belt breaks. Everything would be fine if the belt simply broke, but on some engines the valves immediately bend. Why is this happening?
The fact is that when the timing belt breaks, the camshaft, which drives the valve, stops, and the internal combustion engine crankshaft continues to rotate and push the pistons. The valves that are supposed to close remain in the lowered position and the rising pistons meet them.
How valves bend:
- The timing chain or belt has broken.
- The camshaft has stopped rotating.
- The crankshaft continues to rotate and push the pistons.
- Valves that go down and pistons that go up meet at top dead center (TDC).
- Pistons are stronger than valves, so the pistons bend the valves.
That is, if the timing belt breaks, the camshaft stops abruptly, and the engine crankshaft (even if it was immediately turned off) continues to rotate. The camshaft stops instantly and has no residual rotation because the return springs brake its cams. While the internal combustion engine crankshaft is rotating, the pistons will hit the open valves. Although the material of the pistons is stronger and more durable, it happens that the pistons themselves break when they meet the valves.
On which engines do valves bend?
Here is a list of cars different brands and models in the table. Engines on the same machines can be different, so each brand will have its own table, in which there is a column indicating “bend” and a column indicating “do not bend”. So, let's go, let's start with the most popular cars in Russia:

Why does the timing belt break?
As the experience of breakdowns shows, belts do not break only because they are worn out or are of poor quality. There are several more reasons:
- belt wear (especially if there is even a slight misalignment and the belt touches the side of the pulley);
- if the crankshaft of the internal combustion engine is jammed;
- if the pump (the pump that circulates the coolant) has stalled;
- if the belt tension roller is jammed.
The new generation of motors often break down. This is due to the fact that they are being made more and more powerful. The distance between the valves and pistons located in top dead the points are getting smaller and smaller. Therefore, even if the valves are slightly open and they did not have time to close before the pistons arrived, they are instantly bent.
How can you tell if the valves on a specific make and model of car are bent?
This is for real good question, and all drivers need to know the answer. Be prepared, in the event that the timing belt or timing chain breaks, for repairs such as replacing valves, adjusting them, and so on, or, knowing that it does not bend, do not worry again, but carry a spare timing belt with you (if Belting).
If the operating instructions certain brand and the model is written that it does not bend and you do not trust it, or this information is not indicated at all, that is, a practical method for calculating whether the valves on this machine will bend.
In order to find out, you will need:
- remove the casing;
- remove the timing belt;
- set the first piston to TDC;
- slowly rotate the camshaft 720 degrees (that’s two full turns). If the valve does not rest against the piston, it means it does not reach it.
- set the second piston to TDC;
- Also, turn the camshaft 2 full revolutions. If the piston does not touch the valve, then everything is fine.
- find out whether the valves in your car’s engine are bent using a table, a reference book, or with your own hands;
- Carry a spare timing belt with you;
- buy a belt good quality(preferably the same brand all the time);
- periodically check the belt tension and visual inspection for the presence of cuts, burrs, and detachments of ropes;
- When buying a used car from a stranger, it is recommended to change the timing belt, even if former owner said he recently replaced it;
The Lifan Solano car has been produced in China since 2009, and production has been launched in Russia since 2010. The choice fell on the city of Cherkessk, where they opened car assembly production. The car is rightly classified as class “C”, the parameters are very close to the “Golf” family. The car has an attractive appearance, a high-torque engine, and is in demand among the population of many countries.
The power unit of the machine has a belt drive valve mechanism, so many owners and potential buyers will be interested to know how the timing belt is replaced on a Lifan Solano.
The LF481Q3 engine is manufactured in China; according to reviews from car owners, it is a reliable, easy-to-maintain engine. The engine displacement is 1587 cm3, which is quite enough for safe traffic in the city and on busy highways.
It has an in-line arrangement of four cylinders. The operation of each cylinder is ensured by two valves intake tract, two valves for exhaust gases. The valves are driven by two camshaft, which are installed in the cylinder head.
The motor can develop a power of 78 kW. The combustion chamber is wedge-shaped to ensure efficient combustion of the fuel mixture.
There are no hydraulic compensators on this engine; the thermal clearances are adjusted by selecting and installing cup-shaped pushers between the valve and the camshaft protrusion. The timing mechanism of this motor is driven by a toothed belt. The machine can also be equipped with an LFB479Q engine, which has a displacement of 1800 cm3 and develops a power of 128 hp. With.
Do Lifan valves bend?
This question arises for many car owners who have heard about problems when the belt breaks on other car models. I immediately want to reassure them that this power unit this doesn't happen. This motor is based on Japanese Toyota 4A-EF, purchased under license. Its designers eliminated the possibility of valve damage due to breakage timing belt. This positive quality adopted by engineers from China. If we talk about engines with a displacement of 1800 cm 3, then according to experts, valve damage in in rare cases Maybe. This mainly happens when the engine is running at high speeds.
Belt replacement
Replace worn spare part you can do it yourself. In addition to the desire to do such work, you need to purchase new parts, prepare tools, two car jacks, a stand for the car, and wheel chocks.
You will also need flat-blade and Phillips-blade screwdrivers and rags. If the job is being done for the first time, then you can print out the timing belt replacement guide for help. The work can be done on a level surface, the procedure will be something like this:
- Tighten the cable hand brake, under rear wheels install wheel chocks and remove them with a wheel wrench wheel bolts. Raise the car, install a stand under the body, and remove the right front wheel.
- It is also necessary to remove the mudguard from right side. After this, the second jack is installed under the engine crankcase, having previously placed a wooden gasket so as not to damage the engine sump.
- Filming high voltage wires from the spark plugs, dismantle the valve cover along with the gasket; experts recommend replacing it.
- Raise the motor a little and begin to unscrew the three screws on right support power unit.
- Further work is hindered drive belts auxiliary units, they are removed. Loosening the screw generator set, move it away. To loosen the tension you will have to “suffer a little” since the pin tensioner is in an inconvenient place.
- Now you need to remove the belt from the air conditioning compressor, the tension of which is carried out by a roller. By loosening the roller fastener, the belt is removed.
- After this you need to dismantle the plastic protective covers timing mechanism. They break easily, so they should be handled with care. You will have to unscrew the air conditioning compressor and generator, as they interfere with the removal of one bolt on the middle protective casing.
- The time has come for setting the installation marks; when this is done, the crankshaft pulley should be removed. For this purpose they stop in an accessible way prevent the crankshaft from turning, unscrew the pulley mounting bolt and remove it from the shaft. To remove it, you may need a special puller.
- Remove the lower protective housing of the timing mechanism; you will need to unscrew the three fastening bolts.
- Now you need to loosen the fastening tension roller, then remove the timing belt.
- It is recommended to change the belt tensioning mechanism roller at the same time as the belt, so the old unit must be removed from the engine.
- Installing a new belt is performed in the reverse order. Before starting work, carefully check the alignment of the installation marks. First of all, install the tension mechanism, then the timing belt. It is put on the crankshaft gear, then go clockwise. Tension the drive by turning in the direction of the arrow on the tension roller body, followed by fixing the fastening screw. At the end of the work, turn the engine crankshaft twice, and carefully check the alignment of the installation marks.
Alignment marks
The correct location of the valves in the cylinder head is ensured by installing all parts in a certain position. For this purpose there are alignment marks on the crankshaft, camshaft drive gear, camshaft pulleys. Crankshaft should be turned until the piston of the first cylinder is at top dead center. This position will be indicated by the mark “E” on the camshaft housing and “K” on the pulley, which must match.
The crankshaft pulley also has a mark that matches the “0” mark on the cylinder block. Wherein keyway will be in a vertical position.
Replacement timing
There are owners of Lifan Solano who operate the car for 100 thousand km or more without replacing the timing belt. There is no need to listen to their advice, since the quality of the spare parts used varies, and not all of them can last this long. long term. The optimal mileage should be approximately 60 thousand km, these are the recommendations of the engine manufacturers.
