Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 8. By this time, the coolant level inside the radiator filler port may be lower. If the level is lower, add more of the proper DEX-COOL® coolant mixture through the fill port until the level reaches the base of the fill port. 9. Then replace the pressure cap. At any time during this procedure, if coolant begins to flow out of the fill port, reinstall the pressure cap. Be sure the pressure cap is hand-tight and fully seated. 10. When the engine has cooled, check the coolant in the coolant recovery tank. The level in the coolant recovery tank should be at the COLD FILL line when the engine is cold. Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer's instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. Adding Washer Fluid Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 298 for reservoir location. 316
