Specs and approvals listed by the manufacturer

No OEM approval or spec codes are published on the source we checked. That does not mean the product fails any spec. It means the manufacturer did not list one there. Check the product label or ask the manufacturer.

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 Blue. Colour is a dye, not a spec, so two coolants of the same colour can be different chemistries. See coolant colours explained.
Sold as a concentrate: dilute with distilled or deionised water as the label directs. See premix vs concentrate and the freeze and boil calculator.

Note: Sold in Australia and New Zealand. The catalogue says the full OEM approval list is in separate ACDelco flyers.

Always check your owner's manual first. Use the coolant spec printed in your owner's manual or service information. A listing here is the manufacturer's own claim (meets, exceeds, approved or recommended, worded as they put it). It is not our approval and not a fitment guarantee for your vehicle. If in doubt, ask your dealer or a qualified mechanic.
