Engine Coolant

The cooling system in your vehicle is filled with DEX-COOLRengine 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-COOLRextended 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 ªEngine Overheatingº in

the Index.

A 50/50 mixture of clean, drinkable water and DEX-COOLRcoolant will:

DGive freezing protection down to -34_F (-37_C).

DGive boiling protection up to 265_F (129_C).

DProtect against rust and corrosion.

DHelp keep the proper engine temperature.

DLet the warning lights and gages work as they should.

NOTICE:

When adding coolant, it is important that you use only DEX-COOLR(silicate-free) coolant.

If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner --at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOLRis not covered by your new vehicle warranty.
