Manual Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your retailer's service department and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 402 for the proper fluid to use. 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 297. A 50/50 mixture of clean, drinkable water and DEX-COOL® coolant will: • 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. Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. This system does not have its own reservoir. It receives fluid from the brake master cylinder reservoir. See Brakes on page 308 for more information. 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. 293
