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.
What to Use
Use a mixture of one-haii clean, brinkabie water and
one-half DEX-COOL@ coolant which won’t damage
aluminum parts.
If you use this coolant mixture,
you don’t need to add anything else.

your engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your

other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
