Replacing the fuel filter for Toyota Corolla 120 and 150 body

The filter element in the fuel system of a Toyota Corolla car plays a very large and important role. It removes various mechanical particles and condensate from the fuel, which ensures normal engine operation for a long time. The design of the fuel filter on the Toyota Corolla differs from similar samples on many branded models. In addition, the structural features of the filter module largely depend on the modification of the car body. So, for example, Corolla cars in the 150th and 120th bodies produced in 2007 and 2008 have a fuel pump and filter of different types, which does not in any way affect the principle of their replacement, which is identical.

In this article we will share with you information about the original filter and the frequency of its replacement. You will learn about all types of fuel filters for Corolla on the Russian market and get acquainted with step-by-step instructions for replacing them.

Frequency of replacing the fuel filter on a Toyota Corolla

According to the operating instructions, the fuel filter must be replaced every 80 thousand kilometers. Many car owners drive without changing the filter, thereby almost doubling the recommended mileage. You can’t treat the fuel system and engine this way, because it’s no secret that the quality of domestic gasoline is much inferior to the Japanese standard. Therefore, keep in mind that the fuel filter, like any other cleaning element, cannot last forever and its resource is limited by the mileage of the car or a certain time interval. Maintenance specialists strongly recommend replacing every 50 thousand km. However, replacing the fuel filter may be required earlier. Certain signs will indicate this to you.

Symptoms of clogging

It is quite difficult to detect obvious symptoms of a clogged filter element. This is due to the fact that the filter capacity gradually decreases. Therefore, its clogging can only be judged by indirect symptoms. The most common manifestations of the need to pay attention to the fuel filter are:

• the motor is unstable under load;
• the car's dynamics are gradually deteriorating;
• the power unit stops periodically, especially during intense acceleration;
• the engine does not start the first time;
• The sound of the fuel pump has changed, you can hear that it is working hard.

Signs of a clogged fuel filter

Many Toyota Corolla car owners start replacing the filter only when there are clear signs of a decrease in the throughput of the cleaning element or when the engine fails completely. Since filter clogging occurs at a slow pace, it is not immediately possible to notice the obvious symptoms of its poor performance. And further operation with a clogged filter has a negative impact on the engine’s turnaround time, which is reduced.

Here are the main signs of a clogged filter:

• Uneven engine operation both at idle and under load
• Slow acceleration
• Unstable engine starting
• Unexpected engine stalls

Types of fuel filters for Toyota Corolla on the Russian automotive market

Many auto stores offer a choice of at least three types of products of this type for Toyota Corolla. First of all, these are products from Chinese and Korean manufacturers, as well as the original version. Many motorists do not consider that the quality of filters of different types varies greatly. The main thing is that when replacing the filter, correctly install the sealing gaskets that come with them.

Depending on the modification of the Toyota Corolla car body and the year of manufacture (before 2007 or after), you should individually select a fuel filter that is suitable for the design. There are designs for fuel supply units from the gas tank, where the filter is located in the pump itself, so replacement has to be carried out as a whole module. The procedure is expensive, but the car owner still has no choice. Unlike these Toyota models, Corolla cars produced in 2008 were equipped with different designs of fuel filters, which can be replaced and installed separately from the fuel pump.

A rich assortment of foreign spare parts allows the car enthusiast to make his choice on a line, on one side of which is the cost of the product, on the other - the high quality standard of replacement parts. For example, the price for individual copies exceeds about 10,000 rubles. This is especially true for original products made from non-separable filter and pump units.

So, before replacing the fuel filter, be sure to familiarize yourself with fire safety precautions, and also stock up on the necessary tools and spare parts.

When to change filters - expert recommendations

The fuel filter in a car is used to clean the fuel tank, which may contain various debris that has accumulated during refueling, as well as solid particles and impurities in the poor-quality fuel mixture. The operation of your engine, as well as its spark plugs, depends on the timely replacement of this part. Therefore, you should not save on purchasing high-quality spare parts - the cost of engine repair will be much higher.

If the main Toyota Corolla filter is connected to the fuel pump in the gas tank, then the additional filter is located under the hood of the car. The device is designed to completely filter various impurities that enter along with gasoline through the fuel lines. Car manufacturer Toyota Corolla recommends replacing the filter every 70–100 thousand km.

As practice shows, given the low quality of our fuel, it is better to do this once every 50 thousand km. Fuel filter contamination occurs gradually, and changes in vehicle performance will not be noticeable initially.

However, when the fuel filter ceases to perform its functions, it will inevitably begin to affect the performance of the car. It pulls poorly, does not start the first time, and accelerates poorly. This significantly increases fuel consumption. If the filter is not replaced in time, the fuel pump may fail. This happens because the fuel pump is constantly pumping the amount of fuel needed to run the car, and a clogged filter prevents this from happening.

Fire safety during work

When working with the fuel system, compliance with fire safety regulations is a necessary requirement. The penetration of gasoline vapors begins within a few seconds after removing the gas tank cap. The mixture of air and fuel is very explosive, so there should be no open sources of fire nearby!

After removing the pump unit, when work is being done somewhere on the table, the neck opening of the gas tank must be temporarily covered with a dense layer of material: clean film or cloth. In this case, you should not close the car doors, since the interior will be ventilated through them. By the way, it is much better if the work of replacing the fuel filter is carried out outdoors.

Replacing the TF in the 150th body

Replacing the fuel filter on a 2008 Toyota Corolla (or any other) in the 150 body has some differences from a similar procedure on the 120 body. When replacing, make sure the O-rings are in the correct position as they maintain pressure in the fuel system. Since 2010, a safety system has been used, the essence of which is that the fuel pump operates only when the crankshaft rotates. If there is no residual pressure in the system, the starter must crank the engine much longer until the pump creates pressure in the fuel line.

Preparation

Since the design of the modules is similar, there are no special requirements for tools and workplace equipment. You will need the same tools and materials as when replacing the filter on 120 body cars.

Stages of work

When replacing the filter on the 150th case, a number of points should be taken into account:

1. The fuel module is attached to the tank with a plastic threaded ring with a rubber seal. The ring rotates counterclockwise. To remove the ring, you can use a wooden rod, which is attached to the edges of the ring with one end and lightly struck with a hammer at the other. The second option is to use gas wrenches that attach the ring to the ribs.
2. The module has additional fuel lines for ventilation of the tank cavity. Disconnecting the hoses is similar.
3. The module has two seals. Rubber O-ring 90301-08020 is located on the fuel pump where it is installed in the filter housing. The second ring 90301-04013 is smaller and fits into the check valve fitting at the bottom of the filter.
4. When reinstalling, carefully install the nut spacer. Before screwing the nut back on, first install it by aligning the marks on the nut and the housing (next to the fuel line to the engine) and then tighten it.

The main points of the process are explained in photographs.

Step-by-step instructions for replacing the fuel filter on a Toyota Corolla body 120

• The Toyota Corolla 120 fuel filter is accessed by removing the rear passenger seat on the left side of the cabin.

• Next, remove the underbody upholstery located under the seat. To do this, use a “10” key to unscrew the two fasteners (red arrows). Use a screwdriver to remove the piston (yellow arrow).

• We lift the carpet onto the seats. We secure it with the driver's and passenger's seat belts using the red protrusions. Under the mat we see a layer of foam that needs to be removed.

• Now you will see the fuel pump cover, which you can carefully pry up and remove using a knife or flat screwdriver (it sits on the black sealant).

• Before proceeding directly with the replacement, you should thoroughly vacuum the opened cavity, first under the rug, and then above the gas tank.
• Before disconnecting the pipes, we substitute a previously stored canister to drain the remaining gasoline. Next, remove the fuel hoses. The small pipe or return hose can be removed very easily; just pull the yellow bracket to the side with a thin screwdriver. Disconnecting the second hose will also not take much effort, however, if something happens, you can also help yourself with a screwdriver.

• Before directly dismantling the fuel filter, when the pipes are pulled out, you need to start the car and wait two to three minutes until it stalls. As soon as the engine turns off, you can crank the starter a few more times. This process will remove all fuel from the system and also relieve pressure.
• Next, you need to disconnect the battery terminals.
• Next, you should unscrew the eight screws with a Phillips screwdriver or an “8” key and remove the pump unit. Rags will come in handy here, as gasoline will leak out from all the cracks.

• To get to the fine filter and replace consumable components, we begin to disassemble the fuel pump.
• Remove the latch to disconnect the float.

• Next, press the plastic clips in a circle to disconnect the block body at the top.
• Apply slight force to pull the fuel pump out of the rubber seal.

• We insert the fuel pump into the new fine filter housing.
• Then you should rinse and blow out the intake mesh with compressed air and reassemble everything in the reverse order.

If you make the replacement according to all the rules and do not forget the rubber sealing rings, then the engine will start without problems and will work better than before.

Another modification of the Toyota Corolla model with a 150 body produced in 2008 has a large plastic ring with a rubber seal instead of a metal gas tank cap. To remove the block, the ring must be turned counterclockwise to loosen the seal. You can unscrew the ring lid using wooden choppers, which should be placed on the ribs of the lid and carefully hit them with a hammer. During further disassembly, some parts may differ from the design of a Toyota Corolla with a 120 body until 2008. For example, the intake mesh and fine filter look a little different, otherwise everything is almost the same. In general, the replacement process is identical, so you can use the above instructions for a Toyota Corolla with a 120 body.

Features of selection and replacement

On the auto parts market, the owner of a Corolla, both 2008 and newer, can be offered at least three types of filters: Chinese and Korean analogues and originals. Original products usually cost an order of magnitude more, but are of high quality and reliable. How much a Toyota owner is willing to pay for a new filter element depends on his budget.

After 2008, Toyota Corolla began to be equipped with fuel filters that can be replaced if clogged, regardless of the fuel pump, without the need to replace the entire module responsible for supplying fuel to the gas tank.

You should always be very careful with the selection process and buy the right Toyota Corolla fuel filter for your specific vehicle year and body type.

Replacement in cars produced in 2007–2008 with a 120 body

The average time during which the element effectively filters fuel on Corolla E120 cars is 50 thousand km. But it should be borne in mind that this parameter is designed for Japanese streets, the quality of which is much higher than domestic ones. Therefore, if you use a car in our country, the filter must be changed every time after 25-30 thousand kilometers.

In order for the replacement procedure to go quickly and without problems, you need to prepare the following set of tools and other necessary items:

• a new fuel filter, which will be installed to replace the old one (preferably original, although sometimes you come across well-functioning Chinese consumables);

• new O-rings (2 pcs);

• Phillips and flat screwdrivers;
• rags;
• tools for draining excess fuel.

First you need to remove the rear seats and remove the interior trim. Below is the fuel pump cover.

Using a flat screwdriver, carefully, being careful not to damage anything, you need to remove the fuel pump cover.

Next, disconnect the hose and use a Phillips screwdriver to unscrew the 8 bolts.

Once all this is done, you should start the car a couple of times and let it stop to drain any gasoline that may be in the system. Then you need to remove the battery terminals. After this, the pump itself is removed and inspected, and the condition of the mesh is assessed for rough cleaning.

it is necessary to disassemble the float and remove the coarse fine elements, which we replace with new ones.

After installing the new elements, reassemble in reverse order and reinstall the fuel pump.

Replacement in a car with a 150 body

To replace the fuel filter on a Toyota Corolla 150, you will need the same set of tools, as well as a new filter and o-ring. In this modification, the fuel pump cover is made of plastic and equipped with a rubber seal. To remove the fuel pump, you need to turn the ring counterclockwise and loosen the gasket. The further replacement process is the same as for the 120 body.

Consequences of untimely replacement

Neglecting to replace the fuel filter can result in various damage to fuel system elements, which will require expensive repairs. If the filter is slightly dirty, the fuel supply at high speeds deteriorates, which is reflected in a decrease in the overall dynamics of the Toyota Corolla and an increase in fuel consumption. Increased fuel consumption causes overheating and failure of the catalytic converter.

Dirt particles can get into the fuel lines and injectors and inject fuel into the cylinders. Cleaning clogged injectors is a rather expensive procedure, and it does not always help. If the injectors are damaged or severely clogged, they must be replaced.

Choosing a filter on Corolla

Before replacing, you need to carefully select a new filter. Please pay attention to the part number and compatibility with your vehicle. The auto parts market offers the following options:

• for Corolla 180 body part number 23300-2040. Price - one thousand five hundred rubles;
• for Corolla in the 180 body and the Avensis model - 77024-02320, price - from 8 to 9 thousand rubles, since the filter is supplied complete with a pump;
• the original Toyota 77024-12050 is compatible with most modern Corollas and costs 5,500 rubles;
• for body 120, a part with article number 23217-0D090 is suitable, for which you will have to pay 500 rubles;
• fuel filter for Toyota Corolla version 150, body number 77024-12030, priced at RUB 4,500.

Signs of a blockage

In order for the car’s fuel system to work efficiently, it must receive clean fuel, free of dust, abrasive particles, water and various impurities. For this purpose, all kinds of cleaning elements are installed in cars, the main one of which is a filter for incoming fuel.

The fuel filter elements of Toyota Corolla cars in the E120 and E150 bodies are different in design, but the principle and procedure for replacing them are the same.

As a result of operation, the cleaning element gradually becomes clogged, which affects the overall performance of the car. If the high quality of the fuel entering the gas pump is not ensured, the mechanism may fail. And this, as a rule, entails a disruption in the operation of the motor itself.

The manufacturer recommends changing the fuel filter for Toyota Corolla with both 120 and 150 body types no later than every 60–80 thousand kilometers. But given the quality of gasoline in our country, it is better to do this even more often.

The following characteristic signs of unstable car operation indicate that the filter is clogged:

• a significant increase in the volume of fuel consumed in the absence of changes in operating mode;
• acceleration became slower;
• when the engine speed decreases, its power also decreases significantly;
• the car often stalls when stopping, for example, at a traffic light;
• startup becomes unstable, especially after a break of several hours;
• unstable operation of the transmission, lack of a clear response to gear shifting.

A clogged filter that damages the fuel system should be replaced as soon as possible.

How often should I replace it?

Replacing the Toyota Corolla fuel filter in 120 (2000-2007) and 150 (2008-2012) bodies is not provided by the manufacturer as a routine operation. Such work is performed only at the beginning of diagnostic procedures, if a drop in pressure is detected when the load on the engine increases (that is, at times when the engine’s fuel consumption is highest).

Considering that the fuel filter is built into the body of the fuel module and is not cheap even in its non-original form, few people will decide to perform such a procedure as a preventive measure, especially since it is quite labor-intensive. We also recommend performing this procedure first when purchasing a car with more than 70-80 thousand kilometers or when there are specific signs of excessive filter contamination.
