cold!

This is more of a questioning statement looking for affirmation, not trying talk sh!t, blindzebra.

What about any confirmation on this? we know we have no power guys. I just wasn't buying the "rush of cold air around the sensor" statement from blindzebra, and again just asking not trashing! .

yea i dont think its the rush of cold air either. I think its got more to do with engine rpms and the coolant flow. I know when i stop at red lights my temp goes up a little right away. When i floor it in cold or go to a lower gear it drops a lot now. So im guessing this truck just doesnt do well job of controling its flow. Im sure sombodys gonna go crazy trying to defend the perfection of the hummer. But im not ranking on my own truck. Im just saying what it does. Its kinda wierd. I've never had any other trucks do this.

I agree, and I am noticing a minor temp changes now that I know to look for it, but as long as it doesn't overheat Im not complaining. Our trucks are slow, but who cares, look what we can do! You dont need HP to have a good wheeler. 4.03 to 1 TC and 4.56's!!! enough said.

actually my truck overheated a few times in the summer. Dealer replaced the thermostat and something else. Some houseing thing or something. It was overheating when i was driving on the beach.

Engine temp sensor is located at the rear of the cylinder head on the right side. It is not on the intake.

So no one has an answer. Hummer has informed me that no one has called on it but me. I need info from the southern owners (where it is 60 to 80 outside.) so that I can find out if it's just a cold weather thing.

This has come up a couple other times in threads. More flow doesn't necessarily mean drop in temperature. If the water is hot throughout the engine, it's just gonna flow more of the same temp water. I'd guess, because I'm too lazy to go check right now (and forget by the time I get off work every day) that the temp sensor is on the intake of the engine after the rad. Then, when the flow picks up, it's picking up the flow post radiator. If the temp sensor was in the out from the engine, it wouldn't change so much because the engine would keep the temp higher than flowing through the rad. Unless it was a really high-volume pump and pumped all the cool water from the rad through the engine to the sensor so quick it still looked like it was dropping fast, but from what I can remember (it is after all Friday and I'm at work, so my brain isn't working today), the temp drop is almost instantaneous, so that wouldn't make sense, would it??? I think I've confused myself now...

Don't worry Evldave, here what I do get a bearing on the issue at hand, check the temp gauge, good to go. Check the heater, yep got heat form the heater(FU@K its cold up here -40), see any steam from the front of the car, no stream. Fu@k it, the car works lets go play!!!!!!
