The expansion tank is installed in the engine compartment and is attached to the left cup of the upper support of the shock absorber strut.
To check the fluid level, install the car on a horizontal platform. The test is carried out on a cold engine.
The MAX and MIN·marks are marked on the side wall of the tank, between which the fluid level should be on a cold engine.
When the engine is warmed up to operating temperature, the coolant level in the reservoir may be slightly above the MAX mark.
If the level is at or below the MIN·mark, add the fluid recommended by the manufacturer to the reservoir (see Applications).
On a warm engine, the fluid in the cooling system is under excess pressure. To avoid burns, do not remove the expansion tank cap until the engine has cooled to a safe temperature.
If it is necessary to add fluid to the system on a warm engine, stop it.
After 10 minutes, covering the plug of the expansion tank with a rag, unscrew it a quarter of a turn, relieving excess pressure in the system.
We unscrew the cap of the expansion tank and add coolant to the tank, slightly not bringing the level to the MAX mark.
Remove coolant leaks with a rag. We wrap the cover of the expansion tank.
If the liquid level in the expansion tank is constantly decreasing, then there is most likely a leak in the cooling system. In this case, it is necessary to check the tightness of the cooling system and eliminate the malfunction (see Cooling system).
