Over Heating

I have a 1988 GMC K2500 4x4, 5.7 engine, the temp gage goes as high as it can then goes back to normal. It does this all the time. I am thinking the thermostat is the problem but not sure. Any advise would be greatly appriciated. Thanks

Yes, even if you think it might be..... why not go ahead and try a new one? They are cheap. You risk warping the heads or block, and cooking the oil if you keep running it in its condition.

I'm not one for throwing parts at a problem, but if you don't know how old the t-stat is, I'd agree with just replacing it
They are cheap

Is there any pattern the the OH?
Like only at idle or only on the highway? something like that?
