I I NOTICE: Engine damage from running your engine without coolant isn't covered by your warranty. I If there seems to be no leak, check to see if the electric engine fans are running. If the engine is overheating, the fans should be running. If they aren't, your vehicle needs service. How to Add Coolant to the Coolant Recovery Tank If you haven't found a problem yet, but the coolant level isn't at or above the "COLD" mark, add a 50/50 mixture of clean water (preferably distilled) and a proper antifreeze at the coolant recovery tank. (See "Engine Coolant'' in the Index for more information about the proper coolant mix.) NOTICE: In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. Use the recommended coolant. When the coolant in the coolant recovery tank is at or above the "COLD' mark, start your vehicle. If the overheat warning continues, there's one more thing you can try. You can add the proper coolant mix directly to the radiator, but be sure the cooling system is cool before you do it. 143...
