A. Engine Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Cooling Fans (Out of View)
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.
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
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 50 000 km (30,000 mi) 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.
