Mow 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 FULL HOT mark, add a 5 W O 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 coolantmix.) NOTICE: In cold weather, water can freeze andcrack the engine, radiator, heatercore and other parts. Use the recommended coolant. When the coolant in the coolant recoverytank is at or above the FULL HOT mark, start your vehicle. If the overheatwarning 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. 5-20
