Coolant Selection And Additives

WARNING: This page is about a different variant/trim than selected.

The use of aluminum cylinder blocks, cylinder heads and water pumps requires special corrosion protection. Only Mopar® Antifreeze/Coolant (glycol base coolant with corrosion inhibitors called OAT, for Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% distilled water to obtain to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.

CAUTION:

Do not use coolant additives that are claimed to improve engine cooling.
