Car engine cooling system Toyota Corolla 5 (E80)

The main elements of the cooling system
Engine cooling system with a displacement of 1.6 liters (4A-FE) The engine cooling system consists of a radiator, coolant pump, thermostat and electric fan. The cooling system is thermostatically controlled. Until the...

Cooling liquid
At the factory, the cooling system is filled with coolant, which is a mixture of water, antifreeze, anti-corrosion additives. This composition of the coolant prevents it from freezing, prevents corrosion damage to the...

Removal, installation and check of the thermostat
As the coolant temperature rises, the thermostat opens and directs coolant flow through the radiator. If the thermostat valve does not open due to any malfunction, the engine will overheat. You can determine this by...

Checking the temperature sensor of the fan switch
The temperature sensor, depending on the version, is located either in the radiator or in the coolant inlet pipe. It turns on the fan when the coolant reaches a certain temperature. The temperature sensor must be...

Removal and installation of a radiator
As a result of long-term operation of the car, the radiator channels can become clogged with lime deposits. As a result, the efficiency of the radiator is sharply reduced, and the engine overheats. In this case, the...

Removal and installation of the electric motor of the fan
Removing Disconnect ground cable (-) from the battery. Attention: As a result, the on-board computer records are erased, in particular, the fault records and the radio code. Before disconnecting the battery, you must...

Checking the cooling system for leaks
The presence of leaks in the cooling system and the operation of the safety valve in the radiator cap can be checked using a special device. Screw in the device adapter instead of the radiator cap. Caution: Cover the...

Check, removal and installation of the gauge of temperature of a cooling liquid
The sensor measures the temperature of the coolant and sends the appropriate signal to the temperature gauge on the dash panel kit ("torpedo"). The sensor contains an NTC sensing element whose resistance decreases with...

Removal and installation of the pump of a cooling liquid (petrol)
The coolant pump is beyond repair. If there is damage, the pump is replaced entirely. If the shaft seals were damaged, the coolant exited at the air outlet of the pump drive shaft. Removing For gasoline engines, the...

Removal and installation of the pump of a cooling liquid (diesel)
Removing The diesel coolant pump is driven by a toothed belt. Disconnect ground cable (-) from the battery. Attention: As a result, the records of the on-board computer are erased, in particular, the fault records and...

Coolant change
The coolant is changed during Maintenance car. Attention: If the liquid is drained during the repair process, then it must be collected in a container for reuse, as it contains antifreeze and anti-corrosion additives....

Cooling system malfunctions
Cooling system malfunctions Fault: Coolant temperature too high. The temperature gauge needle is in the red zone.
