Toyota Corolla fuel filter: how to select and replace

A car fuel filter is an important element that is used to clean gasoline or diesel fuel from foreign impurities and condensate, helping to extend the life of the engine and related systems. The filter on a Toyota Corolla requires replacement due to both natural wear and premature clogging, and it is important for the motorist not only to carry out the procedure itself correctly, but also to choose the appropriate spare part. This part has its own characteristics depending on the year of manufacture of the car and the type of body: for example, filters for Corolla 120 and 150 have a different design. Despite this, the replacement process does not differ significantly.

Replacing the fuel filter

Often, owners change the part only when there are malfunctions in the Corolla engine or obvious signs that the filter element is clogged. Clogging of the mesh occurs gradually, so the problem may not be detected immediately. If measures are not taken in a timely manner, you may encounter difficulties when starting the engine, a shortened service life and the need to make major repairs more often.

The fact that the Toyota Corolla fuel filter is clogged is indicated by uneven operation of the power unit, slow acceleration, and jerking when moving. The engine may also stall from time to time for no apparent reason. If such problems begin to appear, you must first check the condition of the mesh and, if necessary, replace it.

When to change filters - expert recommendations

The fuel filter in a car is used to clean fuel from the tank, which may contain various debris that got in 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 repairs will be much higher.

If the main filter in a Toyota Corolla is mounted together with 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 come along with gasoline through the fuel pipes. The Toyota Corolla car manufacturer recommends replacing the filter once 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 the car’s performance will not be very noticeable at first.

However, when the fuel filter ceases to perform its functions, this will certainly begin to affect the performance of the car. It may not pull well, does not start the first time, and accelerates poorly. This significantly increases fuel consumption. If the filter is not replaced on time, the fuel pump may fail. This happens because the fuel pump constantly pumps the required amount of fuel for the car to operate, and a clogged filter will prevent it from doing so.

How often should the fuel filter be changed?

The manufacturer claims that it is recommended to replace this element every 80,000 kilometers under normal vehicle operation. Some Toyota owners delay replacement, almost twice the interval specified in the instructions, as a result of which they have to repair the engine much earlier. In addition, in difficult conditions, it is advisable to change the fuel filter more often, especially in regions with unstable fuel quality. Workshop and service station specialists recommend carrying out the procedure every 50,000 kilometers or more often. In addition, replacement may be required if foreign particles enter the fuel, which severely clog the mesh and contribute to accelerated wear.

Procedure

The procedure should be performed in stages. First, remove the negative terminal from the battery to de-energize the fuel system. Then provide access to the part: to do this, you need to remove the bottom upholstery under the rear left seat in the cabin, this allows you to open the lid of the fuel tank cavity.

Removing the fuel pump cover

The cover must be removed. Since it is fixed to the sealant, you will need to pry it off with a screwdriver. Before you start replacing the filter, you will need to vacuum the areas under the bottom upholstery and the container itself.

After this, you need to open the connector that powers the fuel pump. In order to relieve pressure in the fuel system, you need to try to start the engine several times. If this is not done, when you try to disconnect the hoses, gasoline under pressure will spray out. Open the fuel tank. Disconnect the hoses for direct and reverse fuel supply. To pull out the return line, you will need to use a screwdriver and use it to remove the lock; It is easy to recognize, it is yellow in color. Then you need to unscrew the 8 screws using a Phillips screwdriver and pull out the pump unit.

Remove the terminal and disconnect the hoses

The float is disconnected, for which you need to move the latch, after which the upper part is detached: to do this, you need to press the clips, which are placed in a circle. The fuel pump needs to be pulled out, then inserted into the new filter housing. The mesh needs to be washed and blown with air to remove dirt, then reassemble the structure in the reverse order, not forgetting to install new seals.

Old and new filters

These instructions are suitable for replacing the filter on a Toyota Corolla in the 120 body. If we talk about the modification in the 150 body, then instead of a metal gas tank cap, you need to put a plastic ring on the neck, which is equipped with a rubber seal. To remove the block, you need to twist the ring counterclockwise, and after loosening the rubber tab, remove the pump block. To unscrew the part, you can use a hammer; they need to strike carefully through the wooden attachments. The filter for a car in the 150 body is slightly different in design: it has a different intake mesh, and the fine cleaning device comes separately.

Expert advice

To ensure that the replacement procedure does not cause problems, it is advisable to take into account the following nuances:

It is advisable to install the original part and not an analogue, since it is guaranteed to be suitable for the selected modification and has a long service life. If the owner wants to save money and install a cheaper filter, it is better to choose Korean spare parts, since their quality is quite acceptable.
After assembly, problems with starting the engine may occur. This is explained by the fact that the fuel must completely fill the system, and this takes time. There is no need to press the gas pedal to the floor as this will not be effective. Usually it takes 2-3 attempts to start the engine.
During work, it is important to ensure that there are no sources of fire or sparks near the machine. In the process, gasoline vapors enter the cabin, and contact with a flame can result in trouble.
After removing the pump unit, the inlet neck must be covered with film or a thick rag: this helps protect the gas tank from dirt and foreign elements. It is better to leave the car doors open so that the gasoline vapors evaporate before finishing work. It is advisable to carry out the replacement itself in an open area, and not in a garage.

On average, replacing a fuel filter on a Toyota King takes from 30 to 60 minutes, depending on your skills and experience. If you cannot complete the procedure yourself, it is better to contact the service.

Safety regulations

When working to replace the filter under the underbody from the passenger compartment, it is very important to follow fire safety rules. Within a few seconds after removing the gas tank cap, gasoline vapors penetrate into the cabin. Their explosiveness when mixed with air is mentioned everywhere. Therefore, in no case should there be sources of sparking and, especially, open fire!

When the pump unit is removed and work is being done somewhere on the table, the neck of the gas tank should be temporarily covered with a clean film or thick rag. At the same time, you should not close the car doors - the interior will be ventilated through them. It is also preferable to keep the vehicle outdoors while working.

To install a new filter on a Toyota Corolla, you don’t have to contact a service center; you can do the work yourself. To do this, you will need a canister or other container to drain gasoline and rags. You also need a pair of sealing elements (their average cost is 200-250 rubles), two screwdrivers - with a flat head and a Phillips head.

Gasoline vapors are a strong poison for the human body. Chemical poisoning may cause headache, weakness, nausea, and dizziness. In the long term, with constant contact with gasoline, it can act as a carcinogen. Gasoline is also explosive and flammable.

Therefore, the following safety rules must be observed when replacing the fuel pump:

Do not work in a closed or poorly ventilated area;
Eliminate any possibility of contact with open flames (do not smoke, do not illuminate the work area with fire);
To minimize gasoline leaks, before disassembling the flask, drain all the gasoline that is possible into an airtight container;
If a leak occurs, use cleaning material immediately. After use, to avoid the spread of toxic fumes, place in a sealable container;
If signs of poisoning occur, immediately leave the work area and go into the open air. If the condition worsens, seek medical help.
