is unavailable, use a coolant concentrate or prediluted coolant intended for use with
heavy duty diesel engines and with a minimum of the following chemical and physical properties:
• Provides cylinde r cavitation protection a cco rding to fleet study run at or above 60% load capacity.
• Protects the cooling system metals (cast iron, aluminum alloys, and copper alloys such as brass) from corrosion.
The additive package must be part of one of the following coolant mixtures:
• Ethylene glycol or propylene glycol base prediluted (40–60%) heavy duty coolant.
• Ethylene glycol or propylene glycol base heavy duty coolant concentrate in a 40–60% mixture of concentrate with
quality water.
Water quality is important to the pe rformance of the cooling system. Distille d, deionize d, or demineralized water is
recommended for mixing with ethylene glycol and propylene glycol base engine coolant concentrate.
IMPORTAN T:
Do NOT use cooling system sealing additives or antifreeze that contains sealing additives.
