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 or if you need to add coolant to your

radiator, see “Engine Overheating” in the Index.

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:

When adding coolant, it is important that you

use only DEX

-COOL (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

-COOL is not

covered by your new vehicle warranty.
