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.

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....

Hi 442dude. Sorry I some how missed your last repy.
You're correct in the overheating statement. It does not go to RED, however it is going to the last white line which it never has done owning this vehicle. I was lucky to ever see it go to 1/2. I started taking notice to the temperature gauge once the issue started returning after the gas gauge was fixed and it continued to occur. Yes, I originally had the temp just go over 1/2 and the van performed its no start thing, until it cooled down for 10 minutes. This last occurance has taken triple the time to recover.. (eeks..) I will look to discuss with my dealer the area you describe as being a potential culprit. I thank you many times for your input!..
I'll write back with details as they occur. I wonder if this also would be an area for the orignal person I responded to in regards to this issue. Maybe kill two birds here!
Cheers.!

#47 of 178 2003 venture overheating by startingover

Jun 05, 2008 (11:10 am)

I bought my daughter a 2003 chevy venture with less than 50k miles. Ran fine first 5 months, now it is overheating (past half way). I took to a local repair shop I use, they felt it was the computer, fan does not come on soon enough, causing it to overheat, and I had to take to a dealer. Took to a dealer, they said the radiator was full of crud, had to be replaced and the water pump was leaking, price $1500.00. I had both replaced by my local guy who gave me the water pump and said nothing was wrong with it, still feels it is the computer not turning fan on in time, cost $779.00. Dealer says either the fan comes on or it doesn't. Now I have to take it back to the dealer to have it diagnosed again! The dealer said maybe the cause did not show up because of the water pump and radiator. Please, I acknowledge I know litte about cars and I am a woman so they think they can scam me, but that does not make sense. Any sugestions at this time? Can she continue to run the van past half without causing major problems?? Thank for any suggestions.
