I just took my car to get looked at, and had the thremo replaced.
Ran smooth for an hour. Now it's getting closer to 260 degrees
every 4-5 minutes, then goes down to 220-235 range, then
back up 4-5 minutes later. And it's leaking coolant now.
I'm not sure how to broach the subject to my mechanic.
I have a lot of respect for him and his hard work. But man,
the problem just got worse. I'm taking it back in to show my
man the new development. I just took it in because I thought
they'd catch something in there while working on it.
