Removal

WARNING: Never remove the coolant pressure cap under any circumstances while the

engine is operating. Failure to follow this instruction may result in personal injury. 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: To avoid the possibility of personal injury, do not operate the engine with the

hood open until the fan blades have been examined for cracks and separation. Failure to follow

this instruction 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.

CAUTION: 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 engine.

CAUTION: Never remove the coolant pressure cap under any circumstances while the

engine is operating. Failure to follow this instruction may result in damage to the engine.
