ok ill try that i have to get her car sad.gif where can i buy a thermostat? pep boys or anywhere?

 

Yup, Autozone and such. Just about anywhere. Or, Kragen out where you are at.

LOL

Just give them a call to see if they have it in stock first. Usually, they come with a gasket BTW. But find out.

Add me to your AIM if you have any other questions.

 

no offense to everybody else.. but I do not think it is the thermostat.. when they go, they usually just go and the car will overheat no matter if it is moving or standing still.. more so when it is moving as the engine is doing more work without cooling... This sounds like either air in the system or non functional cooling fans..

I am more leaning towards air in the system. When the engine is working, it can still push enough water through itself and the radiator to keep cool.. but when at idle, the waterpump does not have enough power (from the low revs) to force water through the engine past the air pocket that would form either at the top of the head or at the top of the radiator.. If there is air in there, time to start looking for a leak... probably your water pump.

Then you should tell that to my sister's '93 Honda Accord that was doing the EXACT same thing and now that we put in a new thermostat it has stopped. I'm sticking to my previous thought of it being the thermostat based on my experience with her car recently and my experience with my old 1990 Eclipse from just 1 1/2 years ago(samething happened).

 

see, I am just going by my expierences as well.. Either way, hopefully he can figure out what is wrong and fix it.

 

Uhm, Mad? I've never said this to you before, but that's silly.

Air?

No.

Anyways, before replacing a water pump, I think I'd rather try a $15 or $20 thermostat first. If it doesn't fix it, return it.

 

how is it silly, Redz? If there is air at the top of the tank or in the head, that means that the overall coolant level is low in the car. At an idle, when the water pump is not turning that fast, it does not have enough push to force the coolant up into the engine and then to the radiator... When the car is being driven, it is turning a LOT faster and can build up the pressure to force the water up into the head and back to the radiator..

Honestly, I have not taken that hard a look at the way Hyundai has routed the coolant lines on the Tib, but if it is like most every other car I have worked on, then the outlet from the head to the radiator is one of the highest points on the engine..a prime place to get a stubborn pocket of air that refuses to bleed out.

I could be wrong, but you have to admit.. checking to see if the radiator is warm, if the fans are working, or if there is air in the radiator is a very cheap and easy to do check.
