Cooling System: Service Precautions

WARNING: Never remove the coolant expansion tank cap under any circumstances while the engine is operating. Failure to follow these instructions may result in damage to the cooling system or engine and/or personal injury. To avoid having scalding hot water or steam blow out of the cooling system, use extreme care when removing the coolant expansion tank cap from a hot cooling system. Wait until the engine has cooled, then wrap a thick cloth around the coolant expansion tank cap and turn it slowly until the pressure begins to release, step back while the pressure is released from the cooling system. When certain all the pressure has been released (still with a cloth) turn and remove the coolant expansion tank cap. Failure to follow these instructions may result in personal injury.

WARNING: To avoid the possibility of personal injury or damage to the vehicle, do not operate the engine with the hood open until the fan blade has been examined for possible cracks and separation. Failure to follow this instruction may result in personal injury.

WARNING: Disconnect the fan control wiring prior to performing any underhood service since the cooling fan motor could cycle if the ignition switch is left in the RUN position. 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 damage.
