WARNING: To avoid having scalding hot coolant or steam blow out of the

cooling system, use extreme care when removing the coolant pressure cap from a hot
cooling system. Wait until the engine has cooled, then wrap a thick cloth around the
coolant pressure cap and turn it slowly until the pressure begins to release. Step back
while the pressure is released from the system. When certain all the pressure has been
released (still with a cloth) turn and remove the coolant pressure cap from the coolant
expansion tank. Failure to follow these instructions may result in personal injury.

WARNING: Remove fuse 14 from the engine compartment fuse box prior to

performing any under hood service in the area of the cooling fan when the engine is hot,
since the cooling fan motor could operate if the engine has been switched OFF. Failure
to follow this instruction may result in personal injury.

NOTE:

The engine cooling system must be maintained with the correct concentration and type of
anti-freeze solution to prevent corrosion and frost damage. Failure to follow this
instruction may result in damage to the vehicle.

NOTE:

Engine coolant will damage paint finished surfaces. If spilled, immediately remove
coolant and clean area with water.

NOTE:

Vehicles fitted with supercharged engines shown, V8 NA and V6 engines similar.

hot.

Remove coolant expansion tank filler cap.
