The regulation establishes that the Kia Rio 3 fuel filter must be replaced every 60,000 (km) or once every 4 years if the mileage is not used up. Also, the fuel system is serviced when the car starts to behave slurred and unpredictable.

Diagnostics

Here are the cases in which it is necessary to revise the fuel block:

1. Unstable pressure in the fuel system (3.45 kgf / cm2 is considered the standard)
2. The engine began to work with "jerks"
3. The car is reluctant to accelerate
4. Significant fuel consumption is observed

Please note that replacing the Kia Rio 3 fuel filter is included in the list of priority maintenance work.

Therefore, if there are suspicions that the fuel block is junk, then without delay it is necessary to revise and repair it, if necessary.

Materials and tools

1. A set of socket wrenches (in particular, you will need keys for 12 and 8)
2. Screwdriver set (you need a small flat and shaped screwdriver)
3. Coarse filter (mesh)
4. Fine filter
5. Pliers
6. Sealant (for installing the filtration unit cover)

Please note that the filter elements are changed in pairs (both coarse and fine).

Some craftsmen use the Kia Rio fuel filter for coarse cleaning many times. It is enough to blow the mesh with air and it is like new. But it's not as aesthetically pleasing. Moreover, it costs only 3-4 dollars, it is quite possible to buy a new one for such a responsible business.

Regarding the choice of filter elements, it is best to buy a set of original filters. For coarse cleaning, a filter with article number: 31090-1G000 is used. For fine cleaning, a filter is used: 31112-1G000.

Repair work is carried out in 3 stages:

1. Relieve pressure in the fuel system
2. Dismantling the filtration unit
3. Disassembly of the filtration unit and replacement of filter elements

Below is a detailed instruction.

To remove the fuel filter on the Kia Rio, you must first relieve the pressure in the fuel system.

• We turn off the car and get under the hood
• Opening the relay protection panel

• We remove the fuel system relay (this moment is marked in the photo)

• We start the car and wait until all the pressure is out of the system. The car should shut down on its own.
• Take the key out of the ignition

Everything, now you can proceed to the next step.

Dismantling the filtration unit

The filter system is hidden next to the fuel tank. This node is located under the rear seat. To get the Kia Rio 3 fuel filter, first we dismantle the seat ourselves.

• We unscrew the fasteners with a 12 (mm) head. The bolts are hidden in the gap between the backrest and the seat. There are 2 bolts

• We raise the seat and disengage the brackets that fix it

• Pry off the cover of the filtration unit with a knife. She is sealed

• Move the lid to the side
• We take out the wired module (you need to squeeze the latches from the sides)

• We disconnect the vapor supply hose to the adsorbent (just move the clamp with pliers further along the hose or onto the nozzle)

• We remove the fuel supply pipe from the ramp (there are clamps on the sides of the latch, you need to press on them)

• We unscrew the fixing bolts that hold the clamping ring (8 bolts)

• Now we remove the module housing assembly, where the fuel filter is installed on the Kia Rio

We transfer the block to a comfortable table with good lighting. You can sit in a comfortable seat. Parsing a block is a delicate job. Here you need firm and direct hands.

• Disconnect the fuel level sensor wiring harness

• We unfasten the fasteners of the fuel level sensor and remove it. It slides down the guides

• Disconnect the wiring harness from the fuel pump

• We remove the latch of the block of the inlet fuel hose and take out the block with the hose

• Along the way, we take out the rubber sealing ring so that it does not get lost.

• We do the same with the outlet fuel hose block (remove the retainer, take out the block and rubber ring)

• Using a screwdriver, we squeeze out the latches of the guides of the fuel unit cover

• Take the lid off the glass. Very soon our fuel filter Kia Rio will appear

• Remove the wiring harness from the pump
• Using a screwdriver, we pry the clamps of the glass of the filtration unit

• We take out the pump with a fine and coarse filter. There will also be a fuel flow regulator.

• Unfasten the two latches with a screwdriver and remove the pump

• Using a screwdriver, pry off the stopper on the pump nozzle and remove the Kia Rio 3 coarse fuel filter

• We remove the rubber rings from the filter pipe and unfasten the block with the wire to ground

• Using a screwdriver, pry off the lugs of the fuel pressure adjustment latch and remove the latch

• Get the pressure regulator. There will be rubber and plastic rings in the seat, we also take them out

• We take out the fuel supply pipe from the filter. Using a screwdriver, we also take out the sealing ring of the pressure regulator head

• Everything, now the Kia Rio 3 fuel filter is being replaced with a new model

• We assemble the filtration unit in the reverse order

For an experienced specialist, this work takes about 2 hours. By the way, here is a video about it.

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.

The correct operation of an automobile engine depends on many factors, one of which is the effective cleaning of the fuel refueling in the tank. To purify fuel, Kia Rio cars are equipped with special filters. We suggest you find out where the fuel filter is located on the Kia Rio and how to change it yourself.

[ Hide ]

Fuel filter location

To begin with, let's look at where it is, when and how much it takes to change the filter device in a Kia Rio 2010, 2011, 2012, 2013, 2014, 2015 and other model years. These machines have a two-level fuel purification system. The fuel system is equipped with two filter elements located at the rear of the car, in the fuel pump. This is a coarse filter, which is a mesh, as well as a fine one. The latter is made in the form of a plastic block, inside of which there is an element for cleaning. These parts are included in the design of the fuel pump located in the tank.

New cleaning device for Kia Rio

How often do you need to change?

The filtering device in these cars is not designed for the entire service life of the machine. According to the manufacturer's recommendations, car owners need to change the fuel filter on the Kia Rio after 60 thousand kilometers, but only if high-quality fuel is used. Therefore, in fact, the fuel filter changes after 30-35 thousand kilometers.

In addition, you need to change the device when the following signs appear:

• the pressure in the fuel lines of the power unit of the machine has decreased, the normalized indicator is 345 kPa;
• the power unit has become less stable at idle;
• the power of the power unit has decreased, the vehicle needs more time to pick up speed;
• when you press the gas pedal, dips appear;
• the fuel pump began to work more loudly, an uncharacteristic noise appeared;
• increase in fuel consumption.

When the device is just starting to clog, but can still perform its functions, it is difficult for the car owner to determine these signs. At the final degree of pollution, the driver will not be able to start the engine. All signs are the result of a decrease or lack of throughput of the cleaning device. Therefore, often fuel filters are changed before they work out their service life.

The KIA RIO repair and maintenance channel provided a video that details the procedure for changing the filter device.

Filter selection

When performing repairs and replacing the filter device, it is necessary to choose the correct part for installation.

When buying, you should be guided by the catalog numbers of fuel purifiers:

• the device for fine cleaning has the article 31112-1G000;
• fuel coarse cleaning element - number 31090-1G000;
• rubberized sealing ring for the pumping device - 31118-3J300;
• sealing gum directly for the filter - 31115-1 G000.

If you can’t buy original parts for Kia, you can opt for analogues.

DIY replacement process

Replacing the filter device is one of the easiest tasks when carrying out auto repair. For its implementation, it is not necessary to contact specialists, everything can be done independently.

Tools and materials

What you need to replace the part:

• new filter element;
• two screwdrivers - with a cross and a flat tip;
• pliers;
• set of wrenches;
• sealed glue;
• stationery knife;
• special tool for cleaning carburetors.

Stages of work

How the filter device is replaced in Kia Rio cars:

1. First, the rear seat in the car is dismantled. To remove the chair, unscrew the screws located between the bottom and top of the seats with a 12 wrench.
2. Lift the lower part of the seat and remove the brackets that secure it from the mounts. Remove the cushion.
3. In the space under the chair you can see a plastic hatch. This is the protection of the fuel pump, usually it is fixed with a sealant adhesive. To remove the protection, use a clerical knife or a flat-tip screwdriver.
4. So you get access to another hatch, which is fixed to the car body with self-tapping screws. Behind it is the fuel pump. The hatch screws are unscrewed with a Phillips screwdriver.
5. Depressurize the fuel line before carrying out any disassembly work. To do this, start the engine of the machine and disconnect the connector with wires from the plug installed on the pump itself. When the pressure in the fuel system is released, the engine will randomly stall. You won't be able to run it again.
6. Before removing the cover, be sure to wipe it with a cloth to remove dirt and prevent it from entering the pump. Otherwise, it will negatively affect its functionality as a whole. If possible, you can use a vacuum cleaner for cleaning.
7. Disconnect the fuel supply pipes connected to the device by clamping the fasteners of the lines with pliers. Do not remove the rag far away, as part of the fuel will come out of the hose when removed.
8. Using a Phillips screwdriver, unscrew the screws securing the pump unit. Move the ring aside and slowly remove the filter part from the seat. When dismantling, be careful not to spill fuel.
9. Fix the position of the float used to control the level of gasoline in the system.
10. Using a flat-tip screwdriver, pry off the fasteners and disconnect the connected pipes. Disconnect the connectors and move them aside.
11. Carefully remove the latch from the plastic and release the guides to remove them together with the cover. Now, from the so-called glass, you can remove the part for cleaning the fuel.
12. Disconnect ground wire. Use a screwdriver to pry the ring of the filter element and the motor latches, disconnect it.
13. Remove the metal valve. Remove the rubber seal from the filter device.
14. Install a new valve in the filter. Loosen the clamps, dismantle the plastic part together with the seals.
15. Install the new filter in the seat. The assembly procedure begins with the installation of the electric motor on a new filter device and fixing the fastenings of the fuel lines.
16. The new filter is mounted in the glass of the fuel pump. A hatch is installed in place, which is fixed with screws. The wiring connector is connected. The protective plastic cover under the rear seat of the car is processed around the perimeter with hermetic glue and mounted in place.

A Hyundai Solaris / Kia Rio user presented a video detailing the instructions for changing the fuel cleaning device.

Issue price

The cost of the original filter for cleaning fuel in Kia Rio is about 1000-1500 rubles on average. To save money, you can buy an analogue, its price varies around 400-800 rubles.

Problems after filter replacement

Most car owners, after changing the cleaning device, are faced with the problem of difficult starting or the impossibility of starting the power unit. If this happens, we recommend dismantling the filter element and checking its correct installation. Perhaps the reason for the inoperability of the engine is that during installation you forgot to install the seal. Because of this, the fuel will flow back and the pumping device will have to pump it again. This leads to difficulties in starting the power unit. If the sealing gum is worn out and cannot perform the functions assigned to it, a new part must be purchased and installed. As a result of pressure relief in the fuel line, the engine starts poorly at first, but after a few attempts, its operation stabilizes.

What happens if you don't change?

What problems will the consumer face if he does not change the filter device in time:

1. Vehicle traction will decrease. Due to the clogging of the mesh, the throughput of the filter will be lower. This will lead to a decrease in the power of the power unit. The car will not be so frisky, it will lose its dynamism.
2. There will be problems starting the engine. In critical cases, when the filter mesh is completely clogged, it will not work to start the engine at all.
3. If the device is clogged, but can still perform its functions, then fuel consumption may increase. If, for example, the car consumes about 10 liters of fuel, then when using a clogged filter, the consumption can increase to 12 liters.
4. When the driver presses the gas pedal, dips will appear. The motor will not be able to pick up speed.
5. When driving uphill, jerks may occur, especially in such situations, a decrease in engine traction is felt.
6. Standing at traffic lights or idling may cause the engine to stall spontaneously.

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 go. 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.

1. 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).
2. We move the gearshift lever to the neutral position.
3. Activate the handbrake.
4. Remove the rear seat cushion.
5. Remove the cover from the hatch providing access to the fuel tank.
6. We wring out and remove the connector of the supply wiring to power the pump.
7. We also disconnect the hoses that ensure the switching of the pump fittings in the fuel supply circuit.
8. We unscrew the cross-shaped screws (along the perimeter) that fix the pump housing.
9. We remove the pump assembly and the fuel filter (and a glass) from the seat in the tank.
10. 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.
11. Similarly, by prying two latches, we ensure the removal of the fuel pump from the filter housing (to be replaced).
12. 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).
13. We dismantle the drain tube and the pressure regulator itself from the old filter module.
14. We put on the indicated rubber cuffs on the new filter and complete it with the indicated components (regulator and nozzle).
15. We assemble the pump with the filter into a single unit and mount it in a glass.
16. 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.
