RADIATOR CAP
1. Make sure the engine and radiator
are cool.
2. Relieve any pressure in the cooling
system by turning the radiator cap
anticlockwise, without pressing
down.
3. Remove the radiator cap by
pushing down and turning
anticlockwise.
RESERVE TANK
4. The coolant level should be up to
the base of the filler neck. Add
coolant if it is low.
Pour the coolant slowly and carefully
so you do not spill any. Clean up any
spills immediately. Spilled coolant
could damage components in the
engine compartment.
Engine Coolant
5. Put the radiator cap back on, and
tighten it fully.
6. Pour coolant into the reserve tank.
Fill it to halfway between the MAX
and MIN marks. Put the cap back
on the reserve tank.
Do not add any rust inhibitors or
other additives to your vehicle's
cooling system. They may not be
compatible with the coolant or
engine components.
