I checked the FSM and among other things it says: “The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene glycol based coolant with hybrid organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended... Mopar® Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze…
I think the key here is they specifically state to use MS-9769 anti-freeze.
Prestone Extended Life 5/150 states it meets: “property and performance specification requirements of Daimler Chrysler MS-7170, MS-9769”.
