Specs and approvals listed by the manufacturer
- Meets JIS K2234 per Recochem (Japan (JIS))
- Meets ASTM D3306 per Recochem (industry test standard)
Manufacturer wording: OEM Extended Life RED Antifreeze/Coolant meets or exceeds performance requirements ASTM D3306 and JIS K2234.
"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 recommended for use in Toyota/Scion/Lexus and other automotive and light duty vehicles requiring a OAT engine coolant.
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 JIS K2234, 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 Red. 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.
