Oh my gosh, $400.00 for a thermostat, that is crazy!! Sorry to say I too am having the same problem too, but with NO luck on a resolution as well. I am in on any sort of support group if we can get enough people and take the matter to GM. Good luck and if you ever figure it out let me know. I know when my happens again, I am driving my van right to the dealer and say "FIX IT". I can't complain to much Ol Besty has been good to me and has never quite on me. When I notice she starts getting hot I turn my heat on in the van, I know it sounds crazy and when it's 100 degrees outside it's a killer, but it works she cools right down. So, that's what leads me to believe it is a thermostat issue and/or the water pump. Again, good luck and have a great day!

$ 400.00 is about average for a mechanic to do the job...its almost all labor to get to it as you have to take the intake plumbing out and remove the exhaust crossover pipe just to get to it...just like most repair jobs on the Venture, parts aren't very expensive but the labor is a killer due to the way that they shoe-horned the motor in there...

Great advice, makes sense if the gel is thickening up it would be to thick to pass, thanks I'll try that.

I suppose I agree with your comment 442dude. Just seems like a lot when I don't even know if it will resolve the issue.. we'll see what happens.. I'll be sure to post back with any up coming details.. have a great day...

Maybe I missed something but it seems that your problem is that once the engine is warm it is hard to restart and not the engine overheating (temp needle all the way to the right)? I apologize if I missed this...
 
If its hard to start when hot chances are the crankshaft position sensor is going bad...yours wouldn't be the 1st or the last, its been a common problem with GM V6 engines. If its the case, a new thermostat won't make any difference.

ive heard tell of there being a clog in the coolant line in the throttle body causing the throttle position sensor to get fubar'd.....I wonder

Interesting....Hmmmmmmmm...
 
Is there a coolant line to the throttle position sensor? I'm not looking under the hood right now but I don't think so...Perhaps you mean idle air control (IAC)...I've heard of them failing from time to time...but I don't remember a coolant line there either...only one I can think of being near some coolant is the MAP sensor...maybe I'm wrong?

I have a 2000. I have completed the T-stat change. Do not remove the exhaust manifold. Use a 1/4" ratchet with extension and swival socket from behind the exhaust manifold to remove the lower bolt. You will need to remove the air cleaner, hoses, and throttle body. I have done it twice. The first time I used a aftermarket T-stat, then about a year later I was completeing a intake air gasket change and needed to remove the T-stat. It was a good thing the aftermarket was toast. The new one I purchased from Chevy, we will see how it does.

accgmec,
Glad i'm not going crazy. Reading about everyone else having trouble changing a thermostate or paying $400 had me wondering if i was crazy.
 
I too changed my own thermostate easily on my own in my driveway with very little effort.

You're not going crazy, its not a hard job...just time consuming, that's where the high price to a mechanic comes from - time....
