How to Add Coolant to the Coolant Recovery Tank If you haven't found a problem yet, but the coolant level isn't at FULL COLD, add a 50/50 mixture of clean water (preferably distilled) and DEX-COOL@ (silicate-free) antifreeze at the coolant recovery tank. (See "Engine Coolant'' in the Indexfor more information.) With plain water or the wrong mix, your engine could gettoo 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 mix of clean waterand DEX-COOL@coolant. A CAUTION: Adding only plain water your cooling system to can be dangerous. Plain water, some other or liquid like alcohol, boil beforethe proper can coolant mix will. Your vehicle's coolant warning system is set for the proper coolant mix. CAUTION: (Continued) I NOTICE: ~ In cold weather, water freeze and crack the can engine, radiator, heater core and other parts. Use the recommended coolantand the proper coolant mix. 5-18
