over heating issue (40th 370z GTM TT KIT)

BalanBro

Are you sure the A/C system is not overfilled? Check to see if the compressor clutch is disengaged when it runs hot like that. If the compressor is not running when warm air is being blown, it could be that the pressure after the compressor is too high, causing the pressure switch to disengage the clutch.

While driving, it's possible that the additional airflow is cooling the compressed R134a in the condenser much faster, thereby keeping the pressure low and preventing the pressure switch from tripping.

This is just a theory, but it's worth checking out. If you can easily recreate this while idling, you can have a shop hook up a manifold gauge set to monitor the pressure while the blown air becomes hot.

well actually i wouldnt mind checkin out but as i said it doesnt happen while the car is stopping in a shop or something it happens when ur directly under the sun in traffic , so if i try to check it in the shop it wont blow hot air , so am gana take it step by step and first of all change the thermostate back to stock ! and see wht happens til the radiator and stillen front fascia arrive .

Mr.Squeeze

The A/C problem you are having is because the intercooler is blocking the air flow its huge. I use to have the same problem on my 350z,it would clear up once you start moving and get air flow to the front of the car.
