yellowblue CAUTION: Heater and radiator hoses, and other engine parts, can be very hot. Don't touch them. If you do, you can be burned. Don't run the engine 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 leak fixed before you drive the vehicle. How to Add Coolant to the Coolant Recovery Tank If you haven't found a problem yet, but the coolant level isn't at the FULL mark, add a 50/50 mixture of clean, drinkable water and a proper coolant at the coolant recovery tank. (See "Engine Coolant" in the Index for more information about the proper coolant mixture.) CAUTION: 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 system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn't get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and a proper coolant. NOTICE: Engine damage from running your engine without coolant isn't covered by your warranty. If there seems to be no leak, with the engine on, check to see if the electric engine cooling fans are running. If the engine is overheating, both fans should be running. If they aren't, your vehicle needs service. 5-12
