Draining & Refilling Cooling System: Notes
WARNING:
Never remove coolant expansion tank cap under any circumstances while engine is operating unless instructed to. Failure to follow instructions may result in damage to cooling system, engine and/or personal injury. To avoid having scalding hot water or steam blow out of cooling system, use extreme care when removing coolant expansion tank cap from a hot cooling system. Wait until engine has cooled. Wrap a thick cloth around coolant expansion tank cap and turn it slowly until pressure begins to release. Step back while pressure is released from system. When certain all system pressure has been released (still using a cloth), continue removing coolant expansion tank cap.
WARNING:
To avoid personal injury or damage to vehicle, do not operate engine with hood open until fan blade has been examined for possible cracks and separation. Disconnect fan control harness connector prior to performing any underhood service. Cooling fan motor could cycle on even if engine has been turned off. Failure to follow this instruction could result in personal injury.
