Checking the coolant level
The level of cold coolant should be between the MIN and MAX marks on the expansion tank. If the engine is hot, wait about 15 minutes and only then perform the check.
22. Unscrew the expansion tank cap. Considering that the coolant temperature is still quite high even after a quarter of an hour, the cap should be removed, placing a rag on it.
23. Loosen the cap, allow the air to escape from the tank and only then remove the cap.
The coolant should be replaced every two years.
Attention! Coolant can only be added when the engine is cold.
Checking the cooling system
24. When checking the cooling system, you should visually inspect the radiator, water pump, thermostat housing, expansion tank and heater, and also make sure that the hoses on them are tightly seated and secured with clamps.
25. Check that the cooling system hoses are not hardened, brittle or cracked.
26. Make sure the radiator is not damaged.
27. Check the operation of the thermostat, if necessary.
28. Make sure the radiator fan is working properly.
29. If the hoses are compressed after the coolant has cooled, this is a sign of a faulty low-pressure valve on the expansion tank cap.
30. With the onset of the cold season, the concentration of the coolant should be checked and, if necessary, the content of antifreeze should be increased.
