SERVICE AND APPEARANCE CARE If you have to add coolant more than four times a year, have your dealer check your cooling system. WARNING Never turn the surge tank pressure cap - even a little - when the engine and radiator are hot. Loosening 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. The vehicle must be on a level surface. When your engine is cold, the coolant level should be between MAX and MIN mark on the coolant surge tank. The level rises at engine operation temperature and drops again when the engine cools down. Adding Coolant If the level falls below the MIN mark, add the proper coolant mixture at the surge tank, but only when the engine is cool. If the surge tank is empty, a special fill procedure is necessary. See "Cooling System" in this section for instructions on "How to Add Coolant to the Coolant Surge Tank". When replacing the pressure cap, make sure it is hand-tight. Coolant Surge Tank Pressure Cap CAUTION Your coolant surge tank cap is a pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating. See "Capacities and Specifications" for more information. CAUTION If you use the proper coolant, you don't have to add extra inhibitors or additives which claim to improve the system. These can be harmful. Checking Coolant Engine Overheating You will find a coolant temperature gauge on your vehicle's instrument panel. See "Engine Coolant Temperature Gauge" in section 3. The engine coolant surge tank is located on the driver's side of the engine compartment. See "Engine Compartment Overview" in this section for more information on location. WARNING Don't spill coolant on a hot engine. 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. 5-13
