need help :( OVERHEATING C6 Vette....PROBLEM SOLVING HELP PLEASE!
HEY YOU, YES YOU, I NEED YOUR HELP!
my 05 c6 coupe has been overheating recently.
symptoms:
overheats when:
stopped,
slow driving,
traffic,
pretty much whenever its not accelerating at a certain speed.
SO... im thinking its obviously something to do with the fans...
bc it drives fine and stays under 200degrees when actually driving
between 40-70mph. and then itll rise in temperature when stopped or slow speed coming to a stop.
Originally, I thought it was the thermostat, bc i saw coolant under the car leaking,but it was from the car releasing the hot coolant from the pressure which it's supposed to do, so the coolant isNt leaking from any holes or anything Im aware of...well I had the thermostat replaced at the beginning of my problems solving, but I figured that wasnt the case about 30 minutes later when the temperature was rising again.
I dont let it go over a certain point about 210 degrees and like i said,it drives just fine and under 200 degrees when i plan out trips and such with no stop, just highway
does anyone have any suggestions...maybe a fan fuse? the fan motor? fan module? any advice or things I should try to pin point it?
HOPEFULLY IT'S NOT THE MOST EXPENSIVE PROBLEM
i wana get back to NORMAL driving SOON
PLEASE HELP AND RESPOND BACK.....PLEASE.

I'm getting my car back from the shop for the exact same problem. The car would overheat in traffic but was fine on the freeway.
The problem with my car was the fan controller. The part itself is a 4"x4" little box, costs about $200, and is pretty easy to install. If your set up is really messed up, you'll have to replace your fan too, which is another $300 on top of that. Should be a quick fix though.
Good luck!

Hi welcome to the forum, 
How many summers have you driven the Vette in HOT! Texas ?
I live in Sacramento CA and think my water and oil temps get in the 220-230 range in traffic. I'ts been awhile since I've watched. Your weather is certainly hotter.
One possible problem may be a plastic bag sucked up in the radiator, pretty easy to check. Have you tried a search for overheating ? Searching can give you tons of answers pretty quickly. But you'll also find many here who want to help. BTW are you talking water or oil temps ?
Good luck

What does overheating mean?
210 degrees, 230? 250?
Just because a car runs hotter in stop and go traffic and slow driving doesnt mean there's a problem. For example prestone wont boil until 265 degrees.

FIRST thing I would check is make sure radiator does not have leaves, plastic bag or something in front to keep air from going through. Look under front end of car and look at the front of the radiator. Look at the very top. These cars are bad about sucking things up there. I also live in Texas and in the summer, the car may run a little hotter than normal, especially in stop and go traffic. Make sure you have anti-freeze in the water, about a 50/50 mix.

however, in hot weather with the a/c on, if you're saying it never cools below say, 210, then you need to have someone look at your fans. they should be coming full on and take the temp down. sitting in traffic tho will raise the temps, as will stop and go, esp. when the a/c is off and the fans aren't running yet.

Have you checked to see if the electric fans on the radiator turn on? Once the engine is up to temp, the fans will cycle on and off as needed once the coolant temp is above a preset temp. You can also see if the fans come on by turning the A/C on (put climate control to 60 degrees and hit auto).
I would first check with the A/C and see if the fans power up. If they do, I would then let the engine get up to normal temp and see if the fans cycle at idle. If they come on with the A/C but not at idle with high engine temps, you will know the problem is not with the fan itself.
Like the others have said, you do want to make sure first that the engine is really running too hot. What temp are we talking about when you think the engine is "overheating"?

it IS OVERHEATING....i only let it get to 210-215 right now when im driving it.
If i get stuck in traffic...it raise from 200-240 in 3 minutes...it IS overheating,
I just drive smart til I can get it fixed and plan out my trips and only use highways
during down time when there isnt traffic or anything.
If i let it go, it would redline for sure and I'd be stupid to do that, but you know
what I'm saying.
I only say 210 bc I know it will raise if I let it and I dont want to burn up
my engine or cause even more problems.
anyone in Austin,TX, pretty smart about this problem solving???
or knows anyone/auto shop that wont see me as a blonde female walking in and think they
can upcharge me on everything???
-I'm pretty smart about understanding how things work, but as far as the putting to the labor part, I wouldnt know where to and what to replace and how to.....I could take it apart...but it would never be put together again..especially the right way lol.

I would have the anti-freeze protection level checked. It's easy enough to on your own. Go get a anti-freeze tester from your local auto parts store. Dip the tube in the reservoir and get the reading. I forget the # degree. Change the anti-freeze with a 50/50 mixture, if needed.

I know Austin, but I don't know of a great Austin Corvette shop. Suggestion: post a request for good shops in/around town in the regional section of CF. Here: http://forums.corvetteforum.com/southwest-44/
Note: Haven't looked at any of these threads but here's what I found with "austin repair shops" in the advanced search function, and using only C6 region, "southwest."
http://forums.corvetteforum.com/sear...rchid=12703493
I do like the ideas tho of checking the fluid(possibly changing it but it shouldn't need it), looking for obstructions in/around the radiator, and seeing if the fans are coming on at idle, with/without a/c, etc.

high temp
i had the same problem here in fl. everyday was 90 or higher. got tired of fan comeing on all the time. changed to a 160 degee thermostat and that cured my problem. also in hot weather all the time, i reduced my antifreeze from 50/50 to 70 water and 30 percent antifreeze. also put in some waterwetter. car never gets over 200 degrees sitting at a light . runs at 178 degrees on the highway.
