Checking Coolant Adding Coolant If you need more coolant, add the proper DEX-COOL® coolant mixture to the coolant surge tank, but be careful not to spill it. {CAUTION: Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap - even a little - when the engine and radiator are hot. The engine coolant surge tank is located on the passenger's side of the vehicle at the rear of the engine compartment. See Engine Compartment Overview on page 5-12 for more information on location. The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the FULL COLD mark or a little higher. {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. 5-26
