Checking Coolant for Gasoline Engines If your vehicle has a diesel engine, see "Checking Coolant" under "Van Models" in the DURAMAX® Diesel Supplement for information on checking your vehicle's coolant. The coolant recovery tank is located near the center of the engine compartment. See Engine Compartment Overview on page 5-14 for more information on location. {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. {CAUTION: The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the COLD FILL mark, or a little higher. 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. Occasionally check the coolant level in the radiator. For information on how to add coolant to the radiator, see Cooling System on page 5-28. 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. 5-25
