9-22 Vehicle Service and Care 4. Then fill the coolant recovery tank to the FULL mark. 5. Put the cap back on the coolant recovery tank, but leave the pressure cap off. 6. Start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. 7. By this time, the coolant level inside the radiator filler neck may be lower. If the level is lower, add more of the proper coolant mixture through the filler neck until the level reaches the base of the filler neck. 8. Then replace the pressure cap. At any time during this procedure if coolant begins to flow out of the filler neck, reinstall the pressure cap. Be sure the ears on the pressure cap are in line with the vent tube. Pressure Cap Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. See Engine Compartment Overview on page 9-6 for more information on location. If no problem is apparent, but the coolant level is not at or above the FULL mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL® coolant at the coolant recovery tank. See Engine Coolant on page 9-18 for more information about the proper coolant mixture. If the coolant inside the coolant recovery tank is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. Engine Overheating A coolant temperature gage is located on the vehicle's instrument panel. See Engine Coolant Temperature Gage on page 4-19. Check to see if the electric engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, the vehicle needs service.
