Ensure radiator drain cock is closed and block drain hole plug is tight. Add the DEX-COOL® to the radiator, then add clean drinkable water to the cooling system. If you use the old coolant, make sure the solution is clean and clear, and that the solution is a 50/50 mixture of glycol and water. Place a large top funnel in the radiator filler neck or surge tank. Slowly pour in the coolant. Because the thermostat is closed, filling the cooling system may be slow. Remove the cap from the surge tank. Remove the bleed screw (slotted) from the top of the thermostat housing. Pour coolant into the surge tank, and watch for coolant flowing from the bleed screw. When a constant flow of coolant is reached, close the bleed screw at the top of the thermostat housing. Continue to fill the surge tank to the proper level. Install the cap on the surge tank. After filling the cooling system to the full mark on the surge tank, start the engine and let the cooling system warm up. When the thermostat opens, the coolant level may drop. If the level drops, add coolant as necessary. Install the radiator or surge tank cap. Inspect the coolant level in the surge tank. Add coolant as necessary. Tighten fasteners properly.
