If you have a vehicle that has always run the "green stuff," then Havoline Conventional Anti-Freeze/Coolant is the right choice.
It is a low-silicate, all-purpose formula designed for use in both automotive engines and heavy-duty diesel engines, especially those containing aluminum alloys. Havoline Conventional Anti-Freeze/Coolant provides maximum protection in cold temperatures and reduces boil-overs in hot temperatures through its heat transfer properties. Also available as a prediluted 50/50 product for those who wish to have coolant already mixed with deionized water.
For heavy duty use, an initial charge of supplemental coolant additive will be required for liner protection. Please check with your engine OEM's maintenance recommendations.
