I see that there have already been several topics about coolant for this vehicle but they're a few years old now. My 02 Dakota has a 3.9L engine and the owner's manual calls for a 5-Year HOAT, (Mopar PN 5011764AB). It appears that the previous owner did the last flush & fill in 2011 so it's obviously way overdue. I plan to do a citric acid flush before refilling with new coolant.
I have not been able to find any mention previously of Mopar PN 5011764AB so I don't know if it's been superseded by the latest Mopar-spec coolant. Since modern universal coolants all seem to be rated for at least 5 years, would it be safe to use a universal coolant? Prestone AF2100 is rated for 10 years while MotoMaster Long-Life Global Concentrated Anti-Freeze/Coolant is rated for 5 years.
