The higher the quality of the fuel, the more efficient the engine is and the higher its resource. This is clear to everyone, but not everyone is responsible for the choice of gasoline, relying on the decency of oil companies and gas stations. Poor-quality gasoline can ruin a modern engine for literally 20-30 thousand, especially such as the third generation Kia Rio. No, it cannot be called unreliable, but it was designed to work on normal fuel.

That is why timely replacement of the fuel filter can extend the life of the engine. How to change the fuel filter for Kia Rio 3, which filter is better to choose, how much it will cost and when to replace it - we will analyze all these nuances right now.

How to check when to change and where is the fuel filter on Kia Rio 3

Continuing the tradition of almost all modern fuel-injected vehicles, the 1.4-liter engine of the Gamma family receives gasoline already cleaned and at the right pressure in the fuel rail. And the quality of cleaning depends on when to change the fuel filter on the Rio 3

The replacement of the fuel filter for Kia Rio 3 is carried out, according to the maintenance regulations, every 60,000 km or every four years. But given the quality of our fuel and the amount of dust on the roads, experienced drivers try to change both filters more often - about once every 40-45 thousand, or even more often.

Fine filter Kia Rio 3

The main indicator of the health of the power system is considered to be the correct pressure in the system. If the pressure is below normal, we will see all the symptoms characteristic of fuel pump problems, but rather fuel filters:

Coarse strainer

Pump failure and clogged filters lead to a lean mixture, and this in turn causes all of the above symptoms. Not only is driving with a clogged filter or a faulty pump less fun, it's also dangerous for the engine. If so, we check the operation of the system.

How to check the pressure in the Kia Rio 3 power system

There is nothing difficult in checking the pressure. You just need to have a short hose, a tee and a pressure gauge with measurement limits of at least 5 kgf / cm². Checking the pressure in the system is carried out in several stages:

We check the tightness of the fuel line, gasoline is not leaking anywhere.
We check the contacts on the fuel system devices.
We turn on the ignition and listen - the fuel pump should turn on. This will happen if we have not started the engine for several hours. If the motor was started and the pump is silent - it is necessary, it maintains pressure for some time after the engine is turned off.
Relieve pressure in the fuel system. (We will describe how to relieve pressure below).
We connect a tee with a pressure gauge in the gap between the fuel line and the inlet fitting of the ramp.
We start the engine and look at the pressure gauge. At idle, the pressure rate is 3.45-3.55 kgf / cm². If the pressure is less, we check the pump and filter, as well as the fuel pressure regulator. All this economy is located in the fuel module.

Fuel system pressure

After measuring, we release the pressure again, remove the pressure gauge and install everything in place.

The fuel module is a collapsible unit that includes a coarse fuel filter (mesh), a fine filter, an electric fuel pump, a pressure regulator and a fuel gauge sensor.

Choosing fuel filters for Kia Rio 3. Which one is better, part numbers and prices

Having saved on a good filter, we run the risk of forking out for the replacement of nozzles, candles and piston

The manufacturer insists that we use only original fuel filters. They have the following catalog numbers, fine filter:

Remove and change the fuel filter on the Kia Rio. How to relieve rail pressure

The job of changing the filters on Rio 3 is not particularly difficult and we will spend no more than two hours on it if we collect all the tools and consumables. Everything will work out if we are careful and follow the instructions below.

First you need to relieve the pressure in the fuel system, since it is strictly forbidden to depressurize the fuel line under pressure. The pressure is released easily. To do this, we find the fuel pump relay in the mounting block, which is located under the hood. The relay we need is the last one in the left corner. We take out the relay from the board and start the engine.

It will idle until it has exhausted all the fuel from the system and the pressure drops. Now you can remove the fuel module.

We act like this:

Remove the negative terminal from the battery.
Remove the rear seat cushion. To do this, unscrew the bolt with a 12 head and pull the seat up towards you. We remove it from the salon.
We find the plastic cover of the fuel pump hatch, pry it with a flat screwdriver and carefully remove it.
Disconnect the contact terminal from the pump connector.
Using pliers, open the spring clamp and remove the vapor supply hose to the adsorber.
We press the latches on the tip of the fuel intake pipe and remove it from the fitting.
Remove the tube holder from the bracket on the module cover.
With a head of 8, we unscrew the clamping screws around the perimeter. There should be eight.
Remove the clamping washer.
We carefully take out the module assembly, trying not to damage the float leash.
Now carefully remove the sealing ring from the gutter in the tank.
Disconnect the fuel gauge wiring harness...
pulling the wires out...
... pry the retainer with a flat screwdriver ...
... and remove the sensor by pulling it down along the guides.
Remove the fuel pump power wires by unfastening the latch.
With the same screwdriver, carefully pry off the retainer of the gasoline supply hose from the filter to the module.
We get the fixer.
Remove the hose tip, do not lose the rubber seal.
In the same way, remove this hose from the filter fitting.
Loosen the guide clamps on the module body with a screwdriver.
Separate the cover from the body.
On the module case we pry two clamps ...
... and take out the filters, pump and pressure regulator assembly.
Loosen two fasteners at the top.
Carefully remove the pump and tube.
We hook the stopper on the grid ...

The fuel filter is a part that requires fairly frequent replacement. This need is due to the following factors:

the filter, in principle, should be changed approximately every 30 thousand km, these are the recommendations of the manufacturers, which should be followed for normal and durable operation of the vehicle;
poor quality of gasoline sold in the territory of the Russian Federation leads to rapid clogging of the filter component.

If you neglect the timely replacement of this important part of the fuel system, you can get serious problems with the engine, the repair of which will cost much more than the elementary procedure for installing a new filter. It can be carried out by anyone who knows how to hold a screwdriver in their hands.

For example, replacing a fuel filter on a Kia Rio 3 will not be difficult. This will require only new parts, minimal skills in car repair. A viewing hole or overpass is not needed.

The role of the filter in the Kia Rio fuel system

The normal operation of the engine, and, accordingly, the entire car, depends on the serviceability of all components of the fuel system. In turn, the filter component plays a crucial role in the functioning of the entire system. He is responsible for cleaning the combustible mixture before it enters the unit.

Unfortunately, not everyone knows that even expensive brands of gasoline are far from ideal quality, and the purpose of the filter is to eliminate these shortcomings of the product. Litter and all kinds of impurities settle on the filter component of the part. As a result, it becomes clogged and needs to be replaced. The fuel passing through the filter is no longer properly cleaned, and unwanted components enter the unit.

They settle on the inner walls of the engine, as a result, the nozzles are partially clogged, the fuel is sprayed poorly. As a result, the motor starts to work unevenly, gasoline consumption increases significantly.

This is just the beginning of problems in the operation of the car with a clogged fuel filter. A long ride without replacing this part can destroy the car unit, which for cars like the Kia Rio will entail significant costs.

Important! This part for Kia Rio is inexpensive, so its timely replacement will not entail significant costs.

Why is fuel not getting to the engine?

There are two reasons why gasoline stops flowing into the unit:

empty fuel tank. When the liquid level indicator in the tank does not work, gasoline can run out right while driving;
clogged nozzles. In this case, the gasoline entering the fuel system is not sprayed inside the engine.

This is a consequence of a clogged filter component. As a result of its clogging, a low-quality combustible mixture enters the nozzles. The extra elements in it, that is, garbage, clog the thin channels of the nozzles. With significant pollution, they completely stop spraying gasoline in the injector. In this case, you will have to entrust their cleaning to a professional, which will entail additional costs.

The location of the cleaning filters in the Kia Rio fuel system

Gasoline cleaning in the Kia Rio fuel system occurs in two stages: the first is with a coarse filter. It is installed in front of the main filter. Most often, the second cleaning element requires replacement, this is a fine filter. It is he who filters gasoline before it enters the injector nozzles.

Important! Do not wait for the final clogging of the filters. It is better to change them in advance even before the pollution has not affected the operation of the unit.

Filter replacement

Replacing the fuel filter on a Kia Rio at a service station will cost a lot, since the dismantling of this part is associated with the dismantling of the rear seat. It is for this reason that the owners of the third generation Kia Rio prefer to perform the procedure on their own.

Important! It is worth buying a replacement part from official Kia dealers. since cheaper options can be very inferior to the originals in quality.

Dismantling

Replacing the fuel filter on the Kia Rio begins with the dismantling of the obsolete part. At this stage, we act according to the instructions:

After that, you should change the old Kia Rio filter to a new one and assemble the module in the reverse order. After that, the metal cover protecting the filter is put on again. The hose clamp must be clamped as tight as possible. Do not forget to put the fuel tank cap on the sealant. All actions usually take no more than an hour. The main thing is to follow clear instructions for performing work.

Important! To properly disassemble the Kia Rio 3 module, you need to look at the instructions for the car.

Replacing the fuel filter is one of the mandatory procedures for car maintenance. The main task of the element responsible for fuel quality is to prevent gasoline contaminated with impurities from entering the engine. Passing through the filter, the fuel is cleaned mechanically and only then enters the "heart" of the car. This significantly extends its working life, so replacing the old filter with a new one should be approached with all responsibility.

To choose a filter suitable for replacement, get advice from a professional or strictly follow the instructions for the vehicle. Different models may have slightly different ways of constructing and attaching the element, and the wrong filter can be detrimental to engine performance.

The following modifications are suitable for installing a fuel filter in a Kia Rio car:

Procedure for installing a new fuel filter in a carKIA Rio (photo report)

To replace the filter element yourself, you will need:

Phillips and flat screwdrivers;
keys in a set;
pliers;
aerosol or liquid for cleaning the carburetor;
sealant;
new fuel cleaner.

Let's move on to the practical part:

1. In a KIA Rio car, the fuel filter is located under the rear seat. To get to it, you need a seat by unscrewing the bolts with a 12 key.

2. The plastic protective cover is also removable - disconnect it with a screwdriver, you will have to work a little - for reliability it is filled with sealant. Under it is a small hatch.

3. Relieve pressure. To do this, start the engine and disconnect the fuel pump power connector lock.

4. Turn off the fuel supply pipes, drain the remaining gasoline into the prepared container.

5. Unscrew the pump fasteners, remove the ring and pull out the unusable filter.

5. Fix the fuel level with a float, pry off the clamps and remove the tubes. Disconnect connectors.

6. Remove the plastic latch and release the guides for their free extraction together with the cover. Disconnect the minus contact, insert a screwdriver between the motor latch and the filter ring for a quick disconnect.

7. Remove the metal valve. Insert it and the O-rings into the new fuel filter. After loosening the latches, remove the plastic part and install on a new filter.

We return the hatch with guides to their place, fix them with bolts, connect the terminal. The pump is assembled and ready for installation. We close the lid, the edges of which are smeared with sealant.

The fuel filter should be replaced every 60 thousand kilometers, but if in doubt about the quality of gasoline, carry out a routine inspection every 30 thousand kilometers.

None of the motorists will allow themselves to doubt the modernity, practicality and beauty of the Kia Rio 3 model as well as the Kia Rio 2 version from the Korean manufacturer KIA. To ensure uninterrupted operation of the power system, timely replacement of the fuel filter element should be carried out. The regulatory period for such an action is:

every 2 years;
after 60 thousand km and so on.

The “consumable” we are considering needs to check its condition every 30 thousand km.

The purpose of the filter for Kia Rio 2 and other versions of the model is that it prevents dirt and other impurities in the fuel from entering the rail and nozzles. The sources of waste include the following:

substandard fuel, although a quality product inevitably contains up to 0.1% of all kinds of impurities;
the presence of rust on the bottom and walls of the tank in Kia Rio 2 of different generations, as well as in the fuel line.

Timely replacement of the filter will save the owner of the Kia Rio 3 from the failure of the expensive pump of the power system.

The main symptom of clogging

A sign of clogging of this element may be the appearance of twitching of the car on the move. This is fraught with wear and tear of the transmission unit, as well as elements of the clutch assembly and propeller shaft (if rear or four-wheel drive). Also, in this case, the risk of complete clogging of all components of the injection system (or carburetor supply) should not be neglected.

How to replace this consumable yourself

If you are overtaken by an idea and the replacement of the fuel filter will be done by yourself, then this will save on the service. In this article we will tell you how to change the filter, as well as where it is located, but before you start, you will need to purchase a new consumable, for this you only need to know its catalog number.

To successfully implement the process, you will need to use the following tool:

screwdrivers with slotted and cross profiles;
wrenches and pliers.

The operation is not able to take a lot of time, and the presence of a box is not a necessary condition.

Replacement

Replacing the fuel filter is a responsible but not complicated procedure. We will tell you how to change it.

Relieve the pressure in the fuel supply circuit (by removing the pump fuse and starting the motor to work out the remaining fuel in the system).
We move the gearshift lever to the neutral position.
Activate the handbrake.
Remove the rear seat cushion.
Remove the cover from the hatch providing access to the fuel tank.
We wring out and remove the connector of the supply wiring to power the pump.
We also disconnect the hoses that ensure the switching of the pump fittings in the fuel supply circuit.
We unscrew the cross-shaped screws (along the perimeter) that fix the pump housing.
We remove the pump assembly and the fuel filter (and a glass) from the seat in the tank.
Carefully wring out the plastic clips and, having released the guides, we pull out the pump assembly from the cavity of the glass where the fuel filter is present.
Similarly, by prying two latches, we ensure the removal of the fuel pump from the filter housing (to be replaced).
We take the old fuel filter and remove the sealing rings: from the fuel drain pipe, from the gasoline supply fitting, from the pressure regulator (together with a plastic thrust washer).
We dismantle the drain tube and the pressure regulator itself from the old filter module.
We put on the indicated rubber cuffs on the new filter and complete it with the indicated components (regulator and nozzle).
We assemble the pump with the filter into a single unit and mount it in a glass.
Do not forget about the reverse connection of the power wires of the pump motor.

The assembly of the node is performed according to the reverse algorithm. Fuel filter replacement is complete.

If you replace the filter in a service station?

Decided to resort to the help of masters? For this procedure, you can fork out for 1.5 thousand rubles. including the price of the part.
Even while under warranty service, your Kia Rio 3 cannot count on a filter replacement without payment, since this element is positioned as a part subject to the process of natural wear and tear. This also applies to brake pads and discs, lamps, fuses, etc.

Consequence: some owners of Kia Rio 3 tend to refuse warranty service a year after the start of operation.

Outcome

As you can see, self-replacement of the fuel filter is a completely feasible measure. It is recommended that you carefully study the sequence of actions attached here, which is designed to make it easier for the owner of the Kia Rio 3 to complete the replacement procedure. Use filters from trusted manufacturers, which will avoid unpleasant moments associated with interruptions in the operation of motors.

Kia Rio III was equipped with both 1.2, 1.4 or 1.6 liter petrol engines and diesel units (1.1, 1.4 CRDI). Due to the greater distribution of cars with gasoline units, do-it-yourself replacement of the Kia Rio 3 fuel filter will be considered using the most popular 1.4-liter power unit as an example.

How often do you need to replace

According to the manufacturer's prescribed routine maintenance, the fuel filter should be changed every 60 thousand km. During the warranty period of the car for 15 and 30 thousand km, if necessary, the coarse filter element is inspected and cleaned.

The car with lost dynamic characteristics, problems with starting the engine itself can tell you how much to change the TF. But the exact conclusion of the fault of the power supply system in interruptions in engine operation can only be obtained after measuring the fuel pressure in the rail. If the measured value is significantly less than 345 kPa, then the problem is the loss of performance of the fuel pump or a clogged TF.

Choosing a fuel filter for Kia Rio 3

Special requirements for the choice of filter elements should be made only if your Rio is equipped with a Diesel cycle engine or a gasoline unit with direct injection (for example, 1.6 G4FD, which is a GDI series engine). It makes no sense for owners of cars with atmospheric internal combustion engines and distribution injection on valves to prefer original products instead of, for example, Bosch filters.

According to the Hyundai / Kia spare parts catalog, the coarse strainer has a number - 31090-1G000, and the filter element for fine particles - 31112-1G000.

Where is the phone on Kia Rio III

The coarse and fine filter elements on the Kia Rio III are located inside the fuel tank, so the fuel module will need to be dismantled to replace it.

From the tool, you will need cap heads for 8 and 12, a knob or a ratchet with a small extension. Also, do not do without a sharp knife and pliers.

Before starting self-replacement, relieve pressure in the fuel line. To do this, just start the engine, then remove the fuel pump fuse (F3, 15A) from the mounting block in the engine compartment and wait until the engine stalls.

Replacing the fuel filter Kia Rio 3

Remove the rear seat, as this is the only way you will gain access to the fuel module. It is most convenient to unscrew the seat with a socket head for 12 with an extension cord. The mounting brackets are located between the cushion and the back of the rear row of seats. After unscrewing the bolts, lift the pillow (it is held on by 2 latches), after which it can be moved away and completely removed.

You will have access to the fuel section hatch, which is attached to the car body with a sealant. The hatch can be removed by separating the sealant from the body with a knife. If the work is carried out in the cold season, the perimeter sealant can be slightly warmed up with a building hair dryer.

Be sure to clean the hose attachment points, the seat of the fuel module from dust and dirt.
Remove the fuel module power connector (the ignition key must not be in the On position).
Remove the gasoline vapor ventilation hose. Using pliers, squeeze the ends of the self-tightening clamp and slide it behind the fitting. If the procedure is performed in frost, be careful when removing the hose, since the fitting, like the module itself, is made of plastic.

By pressing the latch, dismantle the fuel hose going to the ramp. Also release it from the plastic holder.
Using an 8 socket and extension, unscrew the module cover stop plate.

Remove the fuel module. This should be done as carefully as possible so as not to damage the FLS float.

Dismantling the module and installing a new fuel filter

Disconnect power connectors.
Using a slotted screwdriver, pry off the LLS retainer, then slide the sensor and remove it from its seat together with the float and connector.
Dismantle the locking clips of the corrugated fuel supply hose.
Pull out the outlet tube tip and O-ring. Do the same for the inlet fitting.
Press the latches on the top of the fuel module, after which the cover and glass can be separated.
Pry off the two plastic clips on the cup body and remove the filter element housing holding the fuel pump and pressure regulator.
The fuel pump inside the housing also rests on the latches.
The coarse filter is fixed to the fuel pump with a lock washer.
Disconnect the "-" terminal of the fuel pressure regulator.
Remove the rubber seal from the fuel return fitting.
The fuel regulator is held by a plastic retainer with 2 latches (do not forget to install the plastic thrust ring and rubber gasket during assembly).
Remove the fuel drain pipe from the filter housing.

Before installing a new filter, put the O-rings on the inlet and outlet fittings. After replacing the fuel filter on the Kia Rio 3 yourself and assembling all the components in the reverse order to removal, turn on the ignition several times to make sure the connections are tight and fill the system with gasoline (do not forget the fuse).
