To circulate antifreeze in the engine cooling jacket, a pump driven by the crankshaft is used. During operation, the unit wears out and begins to make noise or leak fluid. Replacing the pump on a Toyota Corolla 150 does not require the use of special equipment and can be done by the owner of the car.

The pump creates forced circulation of coolant.

Replacing the pump on a 2008 Toyota Corolla

At about 130,000 km the engine began to sound louder.
The “shuffling” sound comes from the drive of auxiliary mechanisms. At 143,000 I decided to “throw off the belt” to understand what was going on. “I threw it off”, spun the “rollers” and found that the pump rotates by hand “like dry land” with characteristic “rolls”. However, the coolant level is still normal, no leaks have been observed. I loosened the belt tension a little (by 0.5 mm) - it became quieter...

On Exist I ordered the pump itself - Aisin WPT-140, three elongated bolts and, "heaps" of air filters - Polish "Filtron":

I prepared a “kit” for draining and filling coolant (0 rubles):

If “enough” is enough, then I’ll limit myself to topping up the “red” coolant; if not, then I’ll add distilled water to the best of my ability (slurry - 120 rubles, water 40):

The only thing left is to “agree” with the garage and the tools!

Each power unit of a modern car has its own cooling system, which is driven by a special pump or, as it is also called, a pump. It is she who pumps fluid through the system and prevents the engine from overheating. Like any other mechanism, the pump has its own definite lifespan - over time, its insulation is broken, the bearings become unusable and the moment comes when it needs to be replaced. In this article we will talk about how to replace the water pump on a 2008 Toyota Corolla.

Reasons for replacement

A working pump does not make any extraneous sounds during operation and is sealed. The appearance of a squeak indicates the beginning of emergency wear of the bearings or the penetration of antifreeze through the oil seal onto the raceways. Further operation of the unit leads to destruction of the supports and sudden jamming of the shaft and the associated pulley. The drive serpentine belt will continue to slide along the surface of the roller and after a few minutes will collapse, which will lead to the simultaneous stop of the generator.

A working pump is sealed and does not create sounds.

Common faults

Frequent breakdowns include:

• damage or loss of elasticity of the oil seals, which begin to leak coolant;
• wear of balls or bearing tracks or washout of lubricant by antifreeze, which accelerates the destruction of bearings;
• Damage to the gasket due to incorrect installation or manufacturing defects;
• cavitation destruction of the rotor.

, while you will be able to consider in detail the entire process from start to finish. And you won't have any questions. This is not difficult, if you have changed the pads of your car at least once in your life, then the pump can be dealt with very simply. Although, of course, if you are not familiar with the mechanics of a Toyota car or with any other mechanics in principle, then the best option for you would be a service center where qualified workers can do all the work for you.

Follow all the tips described above and you will not have any questions about replacing the water pump on your Toyota Corolla 2008.

Toyota repair

Reinstalling the water pump on a Toyota Corolla E body will not be a very difficult task. Even a novice car owner who has never encountered this can cope with such installation and installation.

Step-by-step instructions for replacing the pump Before you begin the replacement, first unscrew the generator. And even earlier, mark the tensioner with a marked mark.

Purpose of the pump and prerequisites for its repair

It is important that the marker is waterproof and does not rub off the first time it gets wet. This will make your work easier when you install a new pump.

You also need to remove the battery terminals. After completing these steps, carefully remove the generator without damaging it. This can be done in two ways: Unscrew the generator completely and put it aside for a while.

Partially unscrew the generator so that its main part remains attached only to the lower bolt. Toyota Corolla, with its own characteristics, recommends the first method.

Symptoms of a problem

The fuel pump in most Toyota cars equipped with gasoline engines is installed in the fuel tank. A clear sign of its malfunction is the lack of gasoline in the combustion chamber, as a result of which the car does not start.

Occasionally, the pump may shut down or reduce its performance. As a result, the pressure in the fuel rail becomes lower than normal. In this case, it is difficult to accurately diagnose the fault. It is impossible to do without special measuring instruments.

Replacing the water pump

Once it has been determined that the cause of the failure is the cooling pump, it needs to be replaced. To reinstall the pump on a Toyota Corolla E120 you will need:

• unscrew the radiator tap and drain the antifreeze (those who cannot reach the tap must first remove the battery);
• remove the plastic cover (we will see the engine mount);
• unscrew two bolts, unscrew the third one halfway (do not remove it from the thread, since it is located in a recess);
• a view of the Toyota Corolla E120 pump itself;
• unscrew the three fixing bolts;
• remove the cover and remove the cooling pump;
• replace the oil seal (if necessary);
• replace the timing belt (if required).

Before installing a new water pump, all pipes must be installed on it. After this, perform the steps in the reverse order of removal.

You can also watch the process of replacing the water cooling pump on a 2008 Toyota Corolla in the video. Watching this video will help you more accurately understand how to correctly perform the work of reinstalling a failed auto part:

2008 Toyota Corolla owners need to know how long it should take before replacing the coolant pump.

According to the regulations, installation of this spare part and the timing belt must occur after 100 thousand kilometers of the vehicle. But in practice, all car enthusiasts confirm that the actual reinstallation is carried out after 200 thousand mileage.

Pump: purpose and repair conditions

The water pump is designed to remove excess heat from the Toyota power unit. As a rule, this part is designed to pump liquid through the system, thereby ensuring circulation and timely cooling of all highly heated components. You can see what this part looks like in the photo below.

A prerequisite for replacing this part may be a characteristic squeak when the engine warms up. In addition, you can detect a leak from the pump. If there is a squeak, then it is quite possible that there will be a deposit of antifreeze or antifreeze around the pump. If water is used, you can check the leak only by detecting dripping water.

So, you have discovered a leak or a malfunction in the pump - what to do? It is not at all necessary to contact a service station. It is enough just to buy a new pump and, according to further instructions, change it yourself. This saves both time and money.

Purpose of the pump

The pump maintains continuous circulation of coolant in a large or small circle. Depending on the position of the thermostat valve. Performance depends on the crankshaft speed.

If the unit malfunctions, the engine overheats, which leads to breakdown of the gas distribution mechanism, piston group or warping of the cylinder head with destruction of the gasket. Further operation of the power unit becomes impossible; the vehicle can be delivered to the repair area by tow or recovery platform.

Water pump?

Antifreeze leaked in the area of ​​the pump. Can I buy a new one or replace the gaskets? It didn’t seem to make any noise or whistle. The only thing I changed was the MSK recently, I took off the belt. But it didn’t seem to be too tight.

What does it mean in the pump area?

The only thing I recently changed was Moscow time

This means that I will disassemble it today and see if the oil seals are leaking.

Did you change the oil scrapers, did you EAT OIL? The problem has gone away, or not?

I don’t know yet - I changed it last week. And then the pump started leaking. I'll unsubscribe.

Today I removed the pump and discovered that the top mounting bolt of the pump was missing. Apparently I removed the belt while replacing the MSK, and then installed it, tightened it, it was slightly skewed and leaked. I didn’t notice any play or any other deterioration on the pump itself. Probably it’s on the sealant and I'll put it in.

I didn’t bother with sealant gaskets and replaced the entire pump. Now I don’t expect it to leak/not leak with tension
