If the Engine Overheats The pointer of the vehicle's temperature gauge should stay in the midrange. If it climbs to the red mark, you should determine the reason (hot day, driving up a steep hill, etc.). If your vehicle overheats, you should take immediate action. The only indication may be the temperature gauge climbing to or above the red mark. Or you may see steam or spray coming from under the hood. 3. If you do not see steam or spray, leave the engine running, and watch the temperature gauge. If the high heat is due to overloading, the engine should start to cool down almost immediately. If it does, wait until the temperature gauge comes down to the midpoint, then continue driving. 4. If the temperature gauge stays at the red mark, turn off the engine. 5. Look for any obvious coolant leaks, such as a split radiator hose. Everything is still extremely hot, so use caution. If you find a leak, it must be repaired before you continue driving (see Emergency Towing on page 262 ). Steam and spray from an overheated engine can seriously scald you. Do not open the hood if steam is coming out. 1. Safely pull to the side of the road. Put the transmission in neutral (M/T) or Park (A/T), and set the parking brake. Turn off all accessories, and turn on the hazard warning indicators. 2. If you see steam and/or spray coming from under the hood, turn off the engine. Wait until you see no more signs of steam or spray, then open the hood. Taking Care of the Unexpected Driving with the temperature gauge pointer at the red mark can cause serious damage to the engine. CONTINUED 251
