Steve, I fear there is little Chrysler can do if you do not have an extended warranty, but you can certainly take it to your dealer and try to get "Goodwill Assistance." Don't hold your breath, though. As you most likely know by now, there are a bunch of folks with the same issue that have not received any assistance whatsoever from Chrysler or Stellantis. There are even a couple of members of this forum who have expressed they want to get rid of their Pacificas before what they perceive as a certain head gasket failure.
Just curious, who performed the oil changes on your Pacifica? Do you know what oil was used? Did anyone top off the coolant and, if so, what coolant was used?
