Manufacturer wording: OEM Extended Life ORANGE I Antifreeze/Coolant meets or exceeds performance requirements ASTM D3306, JIS K2234 and is recommended for use and fully compatible with product meeting GM 6277M.
"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.
What the manufacturer says it is for
It is fully compatible with other similarly formulated OAT coolants and is recommended for use in North American cars and light duty vehicles.
Quoted from the manufacturer's page. Coolant.com has not verified fitment for any vehicle, and a listed make or year range is the manufacturer's statement, not ours.
Compatibility notes
- If your owner's manual calls for GM 6277M, Recochem lists that code for this product. Read the exact wording above, and confirm against your manual.
- 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.
- Sold premixed: pour as supplied. Do not add water unless the label says to.
