Exclamation Heater blowing cold air

Before people say search i have but i have some different symptoms that havent shown in the search.

First off I have an 02 WRX fully stage II with an STI radiator.

My car started over heating last night.

It will over heat when i sit at idle at the stop light or traffic. While my car is sitting at idle regardless if it is over heating the heater does not blow hot air.

When i get moving back down the road the car cools down back to normal tempurature. And the air from the heater gets hotter until it reaches normal temp.

The fans do turn on too.

About three weeks ago i replaced my stock radiator for the STI radiator and replaced hoses to.

Right now the two radiator caps on the system are different pressures. With the highest pressure cap on the coollant resivior on the intake manifold with the lower cap on the radiator.

I do have 2 SPT 1.3 bar radiator caps on order which should be here any day.

I am going to get a new thermostat on monday and reflush the system. Hoping that works. If any one knows what the problem is please chime in. As this is my DD and need it back and running asap.

I had what seems to be the same problem; just a real tricky air bubble in the coolant system. I replaced the thermostat twice before I tried this and it fixed it.

Idle the car for a while (I did it for maybe 15-20 minutes) with the radiator cap off. It should splash out a bit so have a rag there to catch it. You can also try to squeeze the main radiator hose to 'burp' it. The air bubble should be released then so it should pull from the reservoir when you replace the cap so make sure you have adequate coolant in your reservoir. If it doesnt seem to pull from the reservoir, (mine had trouble doing it) then add it into the radiator after you shut the car off.

This solved the annoying problem for me, hope it works for you.

Do you think it would take 3 weeks before an air bubble would cause over heating issues?
