Both engine rows recommend Mopar Antifreeze/Coolant 10 Year/150,000 Mile Formula that meets MS.90032.
The 3.6L cooling-system capacity is 13.7 quarts. The 5.7L is 18.3 quarts. The table does not split either engine by a tow package.
No bleed sequence is printed in the capacity table, so none is added. This is publication 19DS-126-AC. If a non-OAT coolant is added in an emergency, the manual says an authorized dealer must drain, flush, and refill the system.
