i have a 1997 GS and i am over heating and its acting weird one time it will be fine then it will jump all the way to red then jump back to mid heat then cool i have a very good idea what it is but can people give me ideas on what they think it might be?

 

anyone?

 

well whats your very good idea?

by the sounds of it i figure it could be your fan not turning on, explaining why it possibly goes down when your driving and it air cools.

but when does it go down? and when does it go up? if you left the car at idle, does it do it then? do the fans ever turn on if you let it idle?

 

the fan is working....i first thought it might have been my head gasket but its not smoking and or having antifreeze coming out of the exhaust

 

anyone????????

 

How fast does it actually go from red, and then back to normal?
If it's quick, it almost sounds like a problem with the gauge.

 

It might be your thermostat. I had a similar problem but mines was jumping up like crazy. I changed my thermostat and the problem was fixed. YOu can give that a try.

 

flush your radiator and get all the air bubbles out of the system and change your thermostat

thanks everyone

 

your radiator is leaking badly if the coolant is all over your hood. i went thru the same thing recently. check your fluid level and if its dry, replace the rad, rad cap, hoses and thermostat all at once. its pretty simple and not too expensive. i got an OEM replacement from http://www.radiatorexpress.com for like 95 shipped.

Yeah but you said it wasnt using any coolant... anyway thermostat and do a coolant flush and you should be good. Theres other things that you could have tested prior to shotgunning it with parts but if it fixes it then sweet.

 

if the thermostat and flush dont work i would also check your water pump

 

check it engine coolent temp sensor, it might be a bad sending unit

 

my fluid was pretty low so i flushed it

 

A reason why it could jump is exhaust gases are passing by and causing it to heat up, this would mean you have a crack somewhere, hope its not that, because that is what happened to me.... i had to get a new engine...
