Cuda...maybe

Those I6 motors have lots of problems it seems. There was a Grand Wagoneer getting a motor replacement in the bay next to my 170 when it got new spark plugs. Whole body was off the Wagoneer for the swap and parts scattered everywhere. No clue how they'll get it back together properly.

The culprit is the ball thermostat design. There was a part revision for 2025.

We got a 2025 Wagoneer Overland, and the 3.0L Standard Output is lively with the 4x4.
There are a couple of bolt-on tuners in the aftermarket; however, I don't think it's worth adding heat to a turbocharged engine.

3.0L High Output version (the same engine in the upcoming 2026 Charger 6-pack) runs 26 psi vs. Standard Output 3.0L runs 22 psi.

Most issues have been with the 3.0L High Output, and some have been with the Standard Output.
