How to Add Coolant to the Coolant Recovery Tank U Heater and radiatorhoses, and otherengine parts, canbe very hot. Don't touch them. If you do, you can be burned. Don't run theengine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leakfixed before you drive thevehicle. If you haven't found a problem yet, but the coolant level isn't at the ADD mark. add a 50/50 mixture of clecrn \,L*crtet(preferably distilled) and DEX-COOL@engine coolant at the coolant recovery tank. (See "Engine Coolant" i n the Index for more information.) I A CAUTION: I 1 NOTICE: Engine damage from running your engine without coolant isn't covered by your warranty. If there seems to be no leak, start the engine again. Seeif the engine cooling fan speed increases when idle speed is doubled by pushing the accelerator pedal down. If it doesn't. your vehicle needs service. Turnoff the engine. Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mixture will. Your vehicle's coolant warning systemis set for the proper coolant mixture. With plain wateror the wrong mixture, your engine couldget too hot but you wouldn't get the overheat warning.Your engine could catch fire andyou or otherscould be burned. Use a 50/50 mixture of clean water and DEX-COOL@coolant. 5-16
