What kind of coolant does a Chevy 2500 diesel take?

The Chevy 2500 diesel truck takes a specific type of coolant to keep its engine running smoothly and efficiently. The recommended coolant for a Chevy 2500 diesel is a heavy-duty, extended-life coolant that meets the GM Dexcool specification.


Coolant Requirements for Chevy 2500 Diesel Trucks


Chevy 2500 diesel trucks are designed to use a specific type of coolant that provides enhanced protection against corrosion, cavitation, and other issues that can arise in high-performance diesel engines. The recommended coolant is a Dexcool-compatible, extended-life coolant that has a service life of up to 5 years or 150,000 miles.



  • Dexcool is a patented, long-life coolant developed by General Motors (GM) for use in their vehicles.

  • Dexcool coolant is formulated to be more resistant to breakdown and provide better protection against corrosion compared to traditional green or yellow coolants.

  • Using the wrong type of coolant in a Chevy 2500 diesel can lead to issues like water pump failure, radiator clogging, and engine damage.


It's important to always check your owner's manual and use the coolant specified by Chevrolet for your 2500 diesel truck.


Coolant Maintenance for Chevy 2500 Diesel


Proper coolant maintenance is crucial for the longevity and performance of a Chevy 2500 diesel engine. Here are some key tips:



  • Change the coolant at the recommended service intervals, typically every 5 years or 150,000 miles.

  • Always use a 50/50 mix of Dexcool-compatible coolant and distilled water.

  • Avoid mixing different types of coolant, as this can lead to compatibility issues.

  • Regularly check the coolant level and top it up if necessary.

  • Have the coolant system flushed and refilled if the truck has been sitting for an extended period.


By following the manufacturer's recommendations and using the right coolant, you can help ensure your Chevy 2500 diesel runs reliably for years to come.
