Changed out the thermostat and all seems to be working fine now. I got a Duralast part tho.. not AC Delco... hope that doesn’t cause any issues down the line. :/

Duralast part failed

Welp... my Duralast thermostat didn’t last even 20 miles before it crapped out. I didn’t not listen on purpose, I bought the part before reading the response. Looks like I’ll have to replace it again! Oh fun. Thanks for the advice!

I’m not an employee of AC Delco, I just advise on facts, I have tried Stant, MotoRad and Duralast, all failed and that was within a short period of time , I sprung for tge AC Delco and , problem solved for over 7 years now , no code.
I see members post about their issues with thermostat and their testimony as to the AC Delco thermostat fixed they issue.
