Here's the breakdown:
* Cummins recommends using a high-quality, extended-life, "HOAT" (Hybrid Organic Acid Technology) coolant. This type of coolant typically has a service life of 5 years or 150,000 miles.
* The specific coolant recommended by Cummins is often branded as "Cummins Coolant" or "Cummins Fleetguard Coolant."
* Avoid using traditional "green" or "yellow" antifreeze, as these are not compatible with HOAT coolants and can lead to corrosion and engine damage.
* Always refer to the owner's manual of your specific vehicle for the exact coolant specifications. It will list the recommended coolant type, color, and any other relevant information.
Important Note:
* The Cummins 6.7 engine used in stationary applications (like generators) may have different coolant requirements. Consult the engine's specific documentation for the correct coolant for your application.
To summarize, it's crucial to use the correct coolant for your Cummins 6.7 engine. Always consult your owner's manual or Cummins documentation for the specific recommendations.
