WARNING:
Never remove the reservoir tank cap when the engine is hot. Serious burns could occur from high
pressure coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quar-
ter turn to allow built-up pressure to escape. Carefully remove the cap by turning it all the way.
