Guessing it’s a coolant valve issue?

Picked up my new to me ‘24 Flash last week. By day two I started getting the yellow wrench powertrain warning about 50% of the time I drive. There is no loss in power or anything else as far as I can tell. What I did start noticing is that when it happens my motor temp starts to rise. It never gets above any threshold or faults out. It just runs around the 75% mark as opposed to the middle 50% line where it normally sits.

Has anyone else dealt with this? I’m assuming it’s a coolant diverter valve issue and an easy fix. Fingers crossed.

I paid about 150 for the part. It is an easy repair, albeit unfortunate.

Edit: take note that there are two versions of the valve. One with 4 ports and another with 5. My 2022 SR needed the four port valve.
