Overheating!

Hello all. First post in this or any Forum, but have read many of your threads and saved countless hours by searching here.

Anyway, having an overheating problem. I just finished replacing intake manifold gasket. The jeep did not overheat prior to this. In fact it ran on the cool side. My question is... is there something I could have done while replacing the intake gasket that is causing it to overheat? Maybe just coincidence?

I am replacing the thermostat tomorrow AM but don't want to start throwing parts at it I don't need. Thanks in advance for the support.

One step that many overlook (myself included) is burping the cooling system as per the TSM. It may seem like such an inconsequential thing, but absolutely imperative. Of course there are many symptoms and cures for overheating and in my case, I've run the course.

I will make sure I do that when I replace thermo tomorrow. I may need to clean my radiator as well. Just seamed strange I didn't have this problem before I changed the manifold gasket. I didn't see any ports I could have blocked.

I will make sure to 'burp' it tomorrow when I do the thermo. Just seemed strange that this problem started only after intake gasket replacement. I didn't see any ports that could have been blocked. I may need to clean my radiator as well.

poke a small hole in the t-stat with an ice pick, it wont effect performance and will allow it to bleed itself.

What temp gauge are you using, and have you confirmed it's accurate?

Stock temp. gauge that I believe is at least somewhat accurate, never went above half way before I changed intake manifold gasket. I have an infared thermometer I can borrow from work later to check. What temp would be overheating? I know my thermostat is 195.

A possible reason this problem didn't rear it's ugly head is that in the manifold replacement you may have dislodged some crud that is now blocking a cooling passage or perhaps gumming up the thermostat. If you have a TSM, just follow the procedures and you'll get on top of it. I've been criticized for the great lengths I went to to get my 360 under control.
