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.

What the manufacturer says it is for

GM® vehicles 1995 & newer (GM®-approved), most Ford® vehicles 2011-2018 and most Chrysler® vehicles 2013 & newer.

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

  • Sold premixed: pour as supplied. Do not add water unless the label says to.
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.
