Make sure the engine and radiator
are cool.
Turn the expansion tank cap
counterclockwise, without
pressing down on it, until it stops.
This relieves any pressure
remaining in the cooling system.
Remove the expansion tank cap by
pushing down and turning
counterclockwise.
Pour coolant into the expansion
tank. Fill it to the MAX line. Put
the cap back on the expansion
tank.
Do not add any rust inhibitors or
other additives to your car’s
cooling system. They may not be
compatible with the coolant or
engine components.
Pour the coolant slowly and
carefully so you do not spill. Clean
up any spills immediately. Spilled
coolant could damage components
in the engine compartment.
