Engine running hot help

If you are going to the trouble of taking the old one out, if it were me I would buy a brand new one and put it in. Thermostats are cheap, thankfully

When you get one, I think there are a few temperature ranges....I have a 350 in mine, there were 2 temp ranges available for mine in stock at the local O'Rileys, I got the one that wouldn't open up until the higher temp was reached ( 190?? can't remember). I don't think there is any problem getting either temp, I got the higher temp one so the cab would warm up more quickly.
