General Information

PURPOSE
The cooling system is designed around the coolant. The coolant must accept heat from engine metal, in the cylinder head area near the exhaust valves. Then carry this heat to the radiator where the tube/fin assemblies of these components can give it up to the air.

CORROSION PROTECTION
The use of aluminum cylinder heads, intake manifolds, and water pumps requires special corrosion protection. Mopar (R) antifreeze or the equivalent is recommended for best engine cooling without corrosion, when mixed only to a freeze point of -37°C (-35°F) to -59°C (-50°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed solution.

CAUTION: Do not use well water, or suspected water supply in cooling system. A 50/50 ethylene glycol and distilled water mix is recommended.
