why is my car running hot???
why is my car running hot??? my car gets hot while driving and pushes all the coolent out of the overflow tank, i just put a hypertech 160 in and had it reprogramed! wtf! it dont get in to the red but it gets right below it, when it should be running cooler, cause of the hyper tech and programing!
programmed incorrect or T-stat just not working...
Take the T-stat out and boil it on your stove and make sure it opens... It should open well before the water actually starts to boil.
Are your fans coming on?

Do a pressure check on your radiator cap.

This could be as well...
Quick question did you bleed the system after you installed??? If you didnt' you probably have some air bubbles that are going crazy...

if you get the stat out you will see a plate with a little hole in it and a spring etc. actually it's alot easier to explain if you just look at the stat whil e on block. but the plate with the little hole in it is what opens... it opens by retracting... if it doesn't retract it doesn't open and then you get hot...
If you put it in a pot of hot water it will or well should open...
If your system wasn't bleed this makes alot sense. There are 2 bleed off vavles that release air in the system. Not all cars require being bleed after such an operation but these do...

I know all about hot LT1's I spent a day trouble shooting mine... if your car was running fine before the new stat and the program then obviously there is a cause and effect to your problem...
First test the stat.... if water isnt' getting buy that just makes sense.. then reinstall.....now you have to figure if it was just not installed correclty..... really the only thing that could have gone wrong is the cap on the radiator... or didn't bleed the system of air.. I'm not sure how either one of those would cause coolant to spew out of your overflow... but I guess to make sense you would have to understand all of the science behind whats going on and I dont'... I'd try all of the above and see what happens... If none of this works you have an issue somewhere.

Same kinda stuff used to happen to me. My first problem was I didnt bleed the system fully and the second was I overfilled the system thinking more would be better. Once I got all the bubbles out of the system it ran fine. When it got hot ~220 or so the coolant just became too pressurized and basically boiled out of my overflow. Hope this helps...
ok today i checked my cap the seal looked all there and in good shape. also when i am ideling it does fine fans come on and everything but one i start driving it gets way above half way. and it seems like the faster i go the hotter it starts getting! oh ya i also bleed my l;ines too, but still getting hot, WTF!!!!!!!
