When to Check and What to Use The hydraulic clutch fluid reservoir cap has this symbol on it. See Engine Compartment Overview on page 5-12 for reservoir location. Engine Coolant The cooling system in your vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in your vehicle for five years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOL® extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see Engine Overheating on page 5-32.

See Owner Checks and Services on page 6-8 and Recommended Fluids and Lubricants on page 6-12. How to Check and Add Fluid Make sure the fluid level is at the MIN (Minimum) line on the side of the reservoir. If it is not, remove the cap and add the proper fluid until the level reaches the MIN line. Give freezing protection down to −34°F (−37°C). 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. 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 the first maintenance service after each 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. 5-29
