tsol

Hey guys I need some up diagnosing my car.

I have a '05 wrx that warms up fine. But once I get up to 70-80k my coolant gauge slowly drops.
I pulled a code with my A/P p0281 if I recall correctly which said coolant t-stat running low temp.
So changing out my t stat is what I would do first. Any suggestions on what t stat to get?? related issues?? Let me know what you guys think.

Thanks in advance

Street car? Factory thermostat.

pressure leak? hopefully not into your oil..how is the power?

or just a bad gauge but check and confirm the coolant level throughout the day and week...hope you figure it out.

i had the same issue a few months back. temp was fine then looked down and it said I was running cold after hard driving( never got a code). I had no leaks at all. turned out the thermostat had failed in the open position. I replaced it and the issue was corrected.
