Heavy-Duty Diesel Coolant

This concentrated red antifreeze is formulated for heavy-duty diesel trucks and is supplied in a one-gallon container. It lowers the overall temperature of the engine cooling system when mixed with water. The product is new and carries a California Proposition 65 warning for reproductive harm.

Mixing Requirement

As a concentrate, this coolant must be diluted with water before use to achieve the correct freeze and boil protection. The final protection level depends entirely on the mixture ratio chosen by the installer. No pre-mixed protection figures are provided for the undiluted product.

Red Colour Identification

The red dye helps identify the fluid type during system checks and leak detection. Buyers needing a different colour standard or a ready-to-use pre-mixed formula should select an alternative product.

Questions about this item

Should I choose the concentrated gallon or a pre-mixed option for my heavy-duty diesel truck?

This concentrated gallon lets you mix the exact ratio your heavy-duty diesel engine needs, typically fifty-fifty with distilled water for full protection.

What does the red colour tell me once the coolant is circulating in the engine?

The red dye identifies the extended-life formulation so you can spot leaks quickly and confirm the correct chemistry is in the system.

Does this coolant meet a specific industry standard that caps its service interval?

It is formulated for heavy-duty diesel applications where extended-life specifications allow longer drain intervals than conventional coolants.
