{ WARNING: Heater, fuel operated heater (FOH), radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle. Notice: Using coolant other than DEX-COOL may cause premature engine, heater core, radiator and fuel operated heater (FOH) corrosion. In addition, the engine coolant may require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by your warranty. Always use DEX-COOL (silicate-free) coolant in your vehicle. A. Radiator Pressure Cap B. Coolant Recovery Tank C.
