The wording above shows which.

Compatibility notes
- If your owner's manual calls for ESE-M97B44-A, PEAK lists that code for this product. Read the exact wording above, and confirm against your manual.
- Chemistry is listed as IAT. 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 Green. 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.
