Thermostat removal? (2006 Torrent)

[bubbagumpshrimp]

PO128 + Running Warm---> Hot = Bad Thermostat? I figure that's a bit of a Captain Obvious question, as the PO128 code specifies "Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature), but I figured that I'd ask. That and this is definitely the cheapest fix as far as running hot goes (well...that and checking the coolant level), so I'll start here.

I see that it's just two bolts to remove to get to the thermostat. Is there any catch here (i.e. bolts prone to breaking)? Thank you.

read the solution section and soak the bolts in a lubricant/rust buster before trying to loosen them.

Sounds like 2 problems, one is the old condition of running too cold (P0128) and the new one, overheating. Gotta find out where the coolant went. Hopefully you don't have a lower intake leak......if so, replace the t-stat while the intake is off. I've replaced a bunch of t-stats on these GM 60* engines, and have not had any issue with the bolts seizing/breaking. Only the head on the lower one stripping from not getting a wrench on it correctly, from someone else then they give it to me to fix lol.
