RAM 2500 Truck 2WD V8-5.7L VIN D (2004)
Coolant: Fluid Type Specifications
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar Antifreeze/Coolant, 5 Year/100,000
Mile Formula (MS-9769), or the equivalent ethylene glycol base coolant with hybrid organic 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.
IMPORTANT: The green coolant MUST NOT BE MIXED with the orange or magenta coolants. When replacing coolant the complete system flush
must be performed before using the replacement coolant.
