  • Meets ASTM D4985 per Prestone (industry test standard)

Manufacturer wording: Prime Orange antifreeze+coolant is designed to work with these specific vehicles: All GM ® vehicles 1995 & newer/GM approved (GMC, Chevrolet, Buick, Cadillac, Pontiac, Saturn, Oldsmobile, Hummer), most Ford ® vehicles 2011 – 2018 (Ford, Lincoln, Mercury) and most Chrysler ® vehicles 2013 & newer (Ram, Dodge, Jeep, Chrysler).

"Meets X per manufacturer" is our shorthand for any of the manufacturer's own phrases: meets, meets or exceeds, approved, or recommended for applications requiring. It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval. The wording above shows which.

Compatibility notes

  • Chemistry is listed as OAT. Mixing different chemistries can shorten coolant life. See OAT vs HOAT vs IAT and use the mixing checker before topping up.
  • Colour is listed as Orange. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
