2015 2500 coolant flush

[MyTruck]

Just finished a coolant flush on my 2150 2500. It wasn't that bad. The radiator drain was on the left side. Use a 10mm allen wrench. For filling, I disconnected the hose on the top radiator on the right side. This hose is from the coolant reservoir. Used distilled water and prestone flush fluid. Drove for about 1 hour with the heater on and drained it. Refilled with distilled water 2 more times to get rid of it. I used Prestone OAT for the final fill 50/50 with distlled water.

Very thorough, as long as you don't have any airlocks in the system you should be good to go.

Carlo, did you ever have an issues from using this method? Was the Prestone okay?

I've had no issues.

I would mark somewhere under the hood, that you did use
Prestone OAT
That way, anyone working on the coolant system knows what is in it & therefore should not pour the wrong stuff in there

I researched this a lot more. Only difference with Prestone oat is the 2EHA. It won’t interact negatively with Mopar OAT. It might with old school green if someone put that in there but I would think that would be assumed anyway.
