Vehicle Care 10-11 Cooling System The cooling system allows the engine to maintain the correct working temperature. When it is safe to lift the hood: { WARNING 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. 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. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL (silicate-free) coolant in the vehicle. { WARNING 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. Engine Coolant The cooling system in the vehicle is filled with DEX-COOL® engine coolant mixture. See Recommended Fluids and Lubricants on page 11‑12 and Maintenance Schedule on page 11‑3 for more information. The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating on page 10‑14. A.
