4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower than the Maximum mark, add more of the proper mixture to the coolant surge tank until the level reaches the mark. 5. Replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. 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. Then check to see if the engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, do not continue to run the engine and have the vehicle serviced. Notice: Engine damage from running the engine without coolant is not covered by the warranty. Notice: If the engine catches fire because of being driven with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty. If Steam Is Coming From The Engine Compartment { WARNING: Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. (Continued) Engine Overheating The vehicle has an indicator to warn of the engine overheating. There is a coolant temperature gauge on the instrument panel cluster. See Engine Coolant Temperature Gauge on page 4‑30. You may decide not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program on page 8‑7. If you do decide to lift the hood, make sure the vehicle is parked on a level surface. 6-30
