Grand Cherokee 2WD L6-4.0L VIN S (1997)
Coolant: Description and Operation
Selection and Additives
The presence of aluminum components in the cooling system requires strict corrosion protection. Maintain coolant at specified level with a mixture of
ethylene-glycol based antifreeze and water. Chrysler Corporation recommends Mopar Antifreeze or equivalent. If coolant becomes contaminated or
looses color, drain and flush cooling system and fill with correctly mixed solution. A 0.25 percent emulsifiable oil is added to the radiator at the factory
to prevent solder corrosion.
CAUTION: Do not use coolant additives that are claimed to improve engine cooling.
