Have been daily driving my 2020 JT since I got it in 11/2019. 51K miles. Did one of those dip test on the coolant and it showed high PH. Plan to do a flush and Refill with new factory coolant ( OAT ). Have heard that the 3.6 is difficult to " burp the air pockets out ". Saw a suggestion to take out the temp sensor located in the thermostat housing. Is this the best way? Any other suggestions? I also have 2 Pacificas that will also be done soon. Any help would be great. Thanks.

Just went out and looked. If I have this in the coolant tank how does the new coolant get into the system? The only opening in the system is the lid to the over flow tank.

Nice but I do not have a cap on my radiator. If I use the Harbour Freight thing how do I add the coolant?

I guess I fill the tank. Crank the truck. Add additional coolant.to the tank. Open and close the air bleed on the thermostat. Going to go look for the air bleed.
