Mopar 50/50 Premixed Coolant Antifreeze 1 Gallon — 10 Year/150,000 Mile Long-Life, Embittered

Mopar 68163849AB is a factory-formulated, 50/50 premixed antifreeze/coolant in a 1‑gallon bottle designed to protect compatible Chrysler, Dodge, Jeep, Ram and Alfa Romeo engines for up to 10 years or 150,000 miles.

This ready-to-use coolant arrives pre-diluted to a 50/50 ratio of coolant and deionized water, eliminating the guesswork of mixing and giving corrosion protection, freeze and boil protection, and system compatibility for vehicles that require Mopar MS.90032/MS.12106 specification fluid. The formula is embittered to discourage accidental ingestion and meets ASTM D3306 Type 3 performance requirements. It’s a direct-fit replacement part number 68163849AB and supersedes earlier Mopar part numbers where listed.

Which vehicles is this Mopar coolant compatible with?

This coolant is intended for many FCA group vehicles that specify Mopar MS.90032 or MS.12106 fluids. It covers a wide model range across Alfa Romeo, Chrysler, Dodge, Fiat, Jeep and Ram lines, including late-model sedans, SUVs, and light trucks.

• Alfa Romeo Giulia/Stelvio (2017–2020)
• Chrysler, Dodge, Jeep and Ram models from approximately 2013–2021 that list MS.90032
• Fiat 500 and other FCA-branded vehicles cited in Mopar parts documentation
• Check vehicle owner’s manual or dealer parts guide for exact compatibility

How does the 50/50 premixed formula make installation easier?

Because the coolant is supplied at a 50/50 ratio, there’s no need to add distilled water or measure concentrate at installation time. That reduces contamination risk and simplifies top-ups and full cooling‑system fills during maintenance or replacement.

• Ready to pour—no mixing required
• Reduces chance of over‑ or under‑concentration
• Minimizes mineral contamination from tap water
• Convenient for emergency top-offs and DIY service

What performance specs and protections does this coolant offer?

The Mopar premix is formulated for long service life and system protection. It provides freeze protection to approximately -34 °F (-37 °C) and boiling protection up to about 265 °F (129 °C) in a closed cooling system, while offering corrosion resistance for common engine metals when used as specified.

• 10 year / 150,000 mile recommended service interval when used per manufacturer guidance
• Freeze protection to -34 °F (-37 °C) and boil protection to 265 °F (129 °C)
