OK so I am driving my 07 gt when it starts (auto) shifting a little funny I glance down and the temp gauge is in the red. I am at a light and I shut the engine off but turn the heat on and let the fan run. No codes, light turns green and i PULL INTO A LOT AND OPEN HOOD AND STEAM IS SPITTING OUT THE CAP. YOU CAN HEAR AND FEEL THE HEAT, i LET IT COOL BY LETTING THE HEATER RUN AND ITHINK THE FAN I DID NOT CHECK BUT THE ENGINE COOLS TO MID WAY. i TAKE OFF AGAIN AND HEAD TO MY GIRLFRIENDS HOUSE AND THE TEMP JUMPS UP AGAIN I BABY IT TO HER HOUSE ANOTHER 6 MILES AND LET HER COOL DOWN OVER NIGHT. nEXT DAY nO PROBLEMS AT ALL.. i WOULD SAY IT WAS A FLUKE BUT IT HAS HAPPENED TWICE IN THE LAST SIX MONTHS. tEMP OUTSIDE WAS NEVER MORE THEN 70 DEGREES AND I HAVE NOT DRIVEN IT MORE THEN 25 MILES.

MY GUESS IS A STICKING THERMSTAT? NOT SURE IF MY FANS ARE COMING ON! DID NOT THINK TO CHECK, I DID PROVE THEY WOULD RUN THOUGH AND NEVER GOT A CODE FROM THESE , PLENTY OF COOLENT AND WATER WETTER.
iT HAPPENENED BEFORE AND AFTER MY CAMS,TORQUE CONVERTOR AND HEADERS.

WHEN I GET BACK IN TOWN I AM CHANGING THE TS FOR STARTERS CAR HAS 25000 MILES AND I AM IN VA.

 

i would try the thermostat too ybnormal, hopefully
that does the trick.

 

I'd bet Hammer's new motor that it's your t'stat stickin.

 

don't gamble my shiny engine away! you just reminded me
it's time for the nightly cleaning.

 

Do not let it overheat again. Those heads are aluminum and they warp very easily.

 

Are standing in garage cleaning your . . . while you stare at it?

 

lol! and whether it's a fast or slow cleaning
is not important...

 

Did a tstat swap fix your issue? It's been pretty hot in Denver and this has been happening the last couple of weeks. I know this is a problem with some of the 06's at least because me and my buddy bought ours within a week and they both have done it.

 

It's my engine. Whoever I choose to run it against is my choice. If I want to clean it or let it be dirty, no one's business.

I say keep it clean, clean it often.

Somebody gotta smoke?
