Whats up everyone, I have searched the message boards and can't find this on, but anyways, I have an 89 iroc with the 5.7 tpi engine. I just recharged my AC and the car is now overheating whenever the ac is on. Car has a brand new radiator, 2 brand new fans that run all the time, new 160 degree thermostat, hypertech chip, and the air dam and deflector are there and in good condition. When I don't run the AC the car never pops above 160, whether in traffic or on the highway when I turn on the AC it slowly starts to rise until it reaches upwards of 260 degrees. Any help you can give will be much appreciated. Ok and just in case you were wondering I am running the correct mixture of coolant.

 

does the second fan run when you turn the ac on? does it ever run? i'd check that out first.

 

ctually both fans run all the time from the time you turn the key on to the time you turn it off.

 

Just to let you all know I am a licensed AC person, So There isn't too much freon in the ac system, I vacuumed down the system and then charged it.
