Filling the cooling system with liquid (VAZ-2121)

Filling is performed when changing the coolant or after engine repair. Filling operations are performed in the following order:

• remove the plugs from the radiator and the expansion tank, open the heater tap,
• pour coolant (10.7 l) into the radiator (the liquid is poured in until it starts to spill out of the neck) and put the radiator cap back in place;
• add the remaining liquid to the expansion tank and close it with the cap;
• start the engine and let it idle for 1-2 minutes to remove air pockets.

After the engine has cooled down, check the coolant level. If the level is below normal and there are no signs of leakage in the cooling system, then top up the liquid.
