Adding Coolant If you need more coolant, add the proper DEX-COOL coolant mixture at the coolant recovery tank, but be careful not to spill it. ® Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see Cooling System on page 5-26. Radiator Pressure Cap The radiator pressure cap is located near the center of the engine compartment. See Engine Compartment Overview on page 5-12 for more information on location. Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. {CAUTION: Turning the radiator pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. With the coolant recovery tank, you will almost never have to add coolant at the radiator. Never turn the radiator pressure cap - even a little - when the engine and radiator are hot. Engine Overheating You will find an engine coolant temperature gage on your vehicle's instrument panel. See Engine Coolant Temperature Gage on page 3-31 for more information. {CAUTION: You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine. 5-24
