Vehicle Service and Care 9-17 { CAUTION An electric engine cooling fan under the hood can start up even when the engine is not running and can cause injury. Keep hands, clothing, and tools away from any underhood electric fan. If the coolant inside the coolant reservoir is boiling, do not do anything else until it cools down. The vehicle should be parked on a level surface. The coolant level should be at or above the KALT/COLD mark on the coolant reservoir. If it is not, you may have a leak at the coolant reservoir pressure cap or in the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system. { CAUTION Heater and 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. If there seems to be no leak, with the engine on, check to see if the electric engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, your vehicle needs service. Notice: Engine damage from running the engine without coolant is not covered by the warranty. Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL® (silicate-free) coolant in the vehicle.
