RWARNING Never remove the coolant recovery cap while the engine is running or hot. If the engine coolant has not been checked for a long period of time the engine coolant reservoir may eventually empty. If the engine coolant reservoir empties, check the engine coolant level in the radiator. Read the following warnings before removing the radiator cap. If it is necessary to fill the radiator, refer to the Engine Coolant Refill Procedure in this chapter for instructions. 1. Before you remove the radiator cap, turn the engine off and let it cool. Even when the engine is cool, be careful when you remove the radiator cap. When the engine is cool, wrap a thick cloth around the cap and turn it slowly counterclockwise to the first stop. Step back while the pressure releases. When you are sure that all the pressure has been released, use the cloth to turn and remove cap. Stand away from the radiator opening. Hot steam may blow out or hot engine coolant may even splash out. 2. 3. 4. 5. 285
