overheating

**galantofva** · 11-14-2007, 02:11 AM

im having an overheating problem. if i sit idle for aroun 5 to ten mins my temp gauge starts to slowly climb. but once i start moving or if i give it gas it starts to slowly come back down. i think its a bad thermostat. Any ideas?

Have you checked your coolant level???

**polishmafia** · 11-14-2007, 07:47 AM

check the coolant and flush it if it needs it, replace thermostat, blow out your radiator, replace the water pump.

if that doesnt work, then youre just as screwed as me. my car does the same thing and i still havent figured it out.

My 99 does it all the time and after replacing the water pump, thermostat, coolant and all of the above. I just gave up. It does not hurt anything so screw it.

when i first got the car it was doin it and it ended up being that there was no coolant in the car, so i refilled it and it stopped. now its doin it agian but there is plenty of coolant in the system. I think its just my thermostat.

Could be the thermostat. Could be the radiator cap. Could be the headgasket. Do whats easiest/cheapest first, start with the radiator cap.

You think my radiator cap isnt keeping pressure?

**galantofva** · 11-14-2007, 12:09 PM

and i dont think that its my head gasket cuz its not smoking. But my valve stem seals are bad if that would have anything to do with it.

Id rather try an $8 part/2 min install first then a $50+ part/1hr+ install.

**galantofva** · 11-14-2007, 12:37 PM

true. So radiator cap first? and my thermostat is only gonna cost me $13.54

did u put coolant in the clear thing or in the radiator?

Im not sure but would a water temp sensor might be one of the problems too :?:

I have a 02 galant with the I4 in it I just got it back from the shop cause I rear ended somebody I have 61k miles on it everything in the front end got replaced like radiator, fans almost everything in the front I drove it for like a week then one day I was driving the temp gauge just started rising I could hear the fans working when im driving it but the temp gauge just keeps rising so I turn it off and it just smelled like coolant and tried to see if my fans are working but for some odd reason when I just have the key on the "on" position and turn on the AC the fans dont come on at all so I let it cool down and I turn it back on and drive about 45 seconds of driving it starts getting hot again can anyone give me any ideas what can be wrong? my coolant reservoir is on full I havent done my timing belt change or any other belts for that matter my water pump seems to be fine I dont have any leaks and if my water pump would have been locked would the belt make noise from the water pump pulley not spinning at all?

might be a bad thermostat.

yeah in fact it was a bad thermostat so I bought one at autozone which I later found out was a mistake because after slapping it on it was fine but it started leaking for the thermostat housing so I tried putting on liquid gasket stuff and that didnt work so finally I just bought another thermostat this time from kragen and I noticed a difference from the o ring in the thermostat the one from kragen had a lil rib in the middle and the one from autozone was pretty much square cut and I bought sheets of gasket material and just made my own out of that now it seems to be fine no leaks and no overheating!
