Coolant: Description and Operation
COOLANT
DESCRIPTION
CAUTION: Use of Propylene Glycol based coolants is not recommended, as they provide less freeze protection and less corrosion protection.
Do not mix coolant types. If coolant other than Mopar Antifreeze/Coolant, 5 Year/100,000 Mile Formula or equivalent is added, the mixed coolant
will have a reduced service schedule.
The use of aluminum cylinder heads, and water pumps requires special corrosion protection. Mopar Antifreeze/Coolant, 5 Year/100,000 Mile Formula
or equivalent ethylene glycol based coolant with corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This
coolant offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water 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. Mixing of coolants other
than specified (non-HOAT), will reduce the 5 year/100,000 mile corrosion protection.
