Specs and approvals listed by the manufacturer

  • Meets MS-12106 per Antifreeze is glycol plus inhibitors. Choose it by your vehicle's specification. (Chrysler / FCA / Stellantis)

Manufacturer wording: Mopar 2026 Vehicle Lubricant & Chemical Catalog: 50/50 prediluted OAT coolant to MS-12106 (68163849AB); concentrate to MS-90032 (68163848AB); "interchangeable".

"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.

Compatibility notes

  • If your owner's manual calls for MS-12106, Mopar 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.
  • Sold premixed: pour as supplied. Do not add water unless the label says to.

Note: Mopar owner's manuals (e.g. 2022 Ram 2500/3500) say OAT coolant should conform to MS.90032 and must not be mixed with HOAT or "globally compatible" coolant.

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.
