Yet another overheating question (this is a long one)

Did you do the combustion gas test of the coolant (engine running) yet? That will confirm HG leak. Overheating can be something else (heater core among others), but the combustion gas test is cheap confirmation before you take everything apart.

Yup. That's exactly what I came across.

I actually have not done that yet. I had thought about the heater core, as well, but I just have a really hard time pulling the trigger on a diagnostic test to tell me I have to pay more money. I'd also have to find someone in this direct area that's able to do it; I don't want to drive it to Florence. That would be a bit too rough on it right now.

 

 

And even if it's not the HG right now, that's going to be my next step. Here in a couple weeks, I'm going to have a LOT of time on my hands. I figure if I can find a garage to work in, I can do it myself.

I would rule out HG leak with combustion gas tester first. If passes, change temp sensor like suggested earlier. If fails, HG time.

 

No sense spending lots of $$ and time to do a job that won't fix your problem.
