car overheating

[BuckChoklit]

I have the same problem especially in really hot weather after I have been driving the car around for a while. It doesnt overheat while I'm crusing but at idle or in traffic the gauge rises. I did everything thermostat, bled the coolant even put a block off piece of aluminium so that the air is forced through the fan and into the rad, but still when its hot it still has the problem. It could be a warped head, but like you its not all the time. I checked to see if it was the head gasket but I dont think it is. I think my problem is that I just need a bigger fan or a bigger rad, so maybe your rad isent working properly or it could be your fan

You either need a bigger radiator, or your radiator is getting HEAT SOAKED from your turbo. Try watter wetter. You've got nothing to lose.

If it JUST started overheating after you replaced all this stuff, then it's most likely something you've done. There's a saying called K.I.S.S. It stands for Keep It Simple Stupid. You probably need to burp your system. What I do is get the car hot, then CAREFULLY let the pressure out of the system by opening the cap a slight amount with layers of towels between your hand and the cap. After you've let out all the pressure, let the car run with the cap off and add coolant as needed.

BTW, when you filled you car back up, did you use 50/50 antifreeze or did you mix the antifreeze/water yourself?

when it first over heated i changed the thermostat and replaced the upper hose...then it over heated again and it was because the lower hose popped out so i replaced it and it was fine...then it over heated again andi checked it and everything was fine so i just replaced the radiator cap because the one it had one looked cheap and so farr, it hasnt overheated...the thing is that i filled it up with water when it overheated on me the second time just so i could get home and im worried about changing it for coolant because it might heat up on me again...im sad to say this but my new car has got me scared

oh, the ac is cold...not super cold but cold...im thinking it needs freon
