When to Check and What to Use The reservoir is located at the back of the engine compartment, on the driver's side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. Engine Coolant Your vehicle was factory-filled with a coolant developed to last for five years or 150,000 miles (240 000 km), whichever occurs first. When coolant is added or changed, use DEX-COOL® coolant. The following explains your cooling system and how to add coolant when it is low.

Give boiling protection up to 265°F (129°C). Protect against rust and corrosion. Help keep the proper engine temperature. Let the warning lights and gages work as they should. How to Check and Add Fluid Check to make sure that the fluid level is at or above the MIN mark. If the level is below the MIN mark, see the instructions on the reservoir cap. Notice: Using coolant other than DEX-COOL® may cause premature engine, heater core or radiator 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. 5-23
