Make sure the engine and radiator
are cool.
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.
Loosen the expansion tank cap by
turning it 1/8 turn anticlockwise.
This will relieve any remaining
pressure in the cooling system.
The coolant level should be up to
the MAX line. Add coolant if it is
low.
Put the expansion tank cap back
on. Tighten it fully.
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 compo-
nents.
Remove the expansion tank cap by
pushing down and turning
anticlockwise. 3.
