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

the
use of coolant other than DEX-ClOOL@ is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL@' coolant which
won't damage aluminum parts. If you use this mixture,
