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

hindi1973 · 05-13-2011, 06:19 PM

well i figured to update to u like i promised i know it has been long but i didnt have time , we took the car to a mechanic and checked everything , all looks good and everything , we bleeded the cooling system and made sure their was no air , also we found out the ac pressure is low around 250 so we made it 550 exacty like the green sticker when u pop the hood , anyway i ordered an upgraded radiator , i want fans but i didnt know where to get one , and gtm site doesnt give u a price when u click on the item there , so i got a CSF radiator with shrouds for our heat which is reachin 115-120f , the only issue which is pissing me off and i have no clue why this is happening , so when i drive and their is no traffic , the ac is flowing fine and flowing cold air , as soon as i get in traffic and it heats up a bit , the ac flows HOT AIR as if i switched the ac off , i tried everything and it seems everytime it heats up it goes on limp mode and switches off the ac automaticly, and when i drive off after i sweat my as* off it gets cold again , i check the oil temp and coolent temp everything seems normal around 220 oil temp and the coolent temp is either on the half mark or one dot pass it which is fine ,

am started to get pissed off ,am tryin to convince my self that when i change the radiator and the coolent system gets better the car will not go to this limp mode , fingers crossed , all help is appreciated !
