When to Check and What to Use How to Check and Add Fluid The proper fluid should be added if the level does not reach the bottom of the diaphragm when it's in place in the reservoir. See the instructions on the reservoir cap. 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 5 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 5-26. Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See Part B: Owner Checks and Services on page 6-26 and Part D: Recommended Fluidsand Lubricants on page 6-33. 5-23
