Checking Coolant If the LOW COOLANT LEVEL message comes on and stays on, it means you're low on engine coolant. If you need more coolant, add the proper DEX-COOLR coolant mixture at the coolant recovery tank. Adding Coolant CAUTION: The engine coolant reservoir is located on the driver's side of the vehicle, above the engine air cleaner/filter. 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. When your engine is warm, the level should be above the FULL COLD mark or a little higher. 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. Add coolant mixture at the recovery tank, but be careful not to spill it. 6-23
