help Car temp increases when idle

ok a little background on my car...
-------------
-changed water pump and timing belt 12,000 miles ago
-car has 209,708miles on it
-car has rough idle due to egr port/valve
-------------

My radiator busted while driving (quite rough) on the freeway so i changed out the radiator and all seemed well but recently my temperature gauge has been acting strange.

The temp gauge increases rapidly when idling and returns to normal when my revs increase. Granted my idle rpm's are lower than recommended (this worsened after the radiator change)

Im thinking that it's either my thermostat or water pump, at first i thought that it was jus air bubbles but that was 2 weeks ago.

Re: help Car temp increases when idle

I have a similar problem. My car overheats when I idle with the A/C on. It takes a while too, like 5-10min but the temps will get 3/4 the way to the top and as soon as I start driving the temp drops immediately. I didn't try just rev'in the engine as I didnt feel comfortable rev'in a hot engine (and I was in a drive through so the other people in line would be like wtf?)

My radiator is fine, recently flushed, new water pump, water levels are fine and turning the a/c pretty much fixes the problem but I live in the dirty souf so no a/c SUCKS! I wouldnt have brought it up on my own but since you have something similar maybe someone could give us both input.

Re: help Car temp increases when idle

I had the exact same problem recently. I changed out the thermostat and everything is fine now.

Re: help Car temp increases when idle

I know this probably isnt ur problem but make sure u aren't running low on antifreeze. I went on a lil trip yesterday and my car was having the same problem. I thought I was just low on antifreeze so i filled it up. It was fine for a while but then the temp gauge started rising pretty quick. Found out I have a leak in one of my hoses. Going back 2day 2 find out where the leak is coming from

Re: help Car temp increases when idle

How many bars does it go up to? 2 is normal, anything over is trouble.

Re: help Car temp increases when idle

yea I hear ya....I have a prob w/ cooling and have read the threads but none pinpoint my challenge. It is similar to yours.....have changed water pump, timing belt, thermostat,just had head job (1mo), temp sending and still keeps overheating!! I think it has something to do w/ head gasket (maybe crappy parts) cause I had an accord w/ similar prob and turned out to be head gasket between 2 cylinders.

Re: help Car temp increases when idle

my bars keep going up i took it to the dealer ship and they said that my head gasket was busted, which caused radiator fluid to leak into my combustion chamber.

So basically my car was trying to burn coolant!! so ive taken off my head and can see the coolant in the chamber.

F*cking bullSh*it i tell you what

Re: help Car temp increases when idle

I believe the problem should be from thermostat
