    A/C recharge port

    Hey guys, could someone tell me where the low pressure a/c recharge port is? I dont wanna screw it up and put it in the wrong port. Ive read that they make em now so they wont fit on the high port, and I also read that the pipe for the low pressure port will always be bigger then the pipe for the high pressure port. Anyways, thanks for the help.

    That's it. Start car, put AC on max cold, hook up recharge hose, pull trigger. Check pressure till it gets in the 40-45psi range when the compressor is running. Very easy.

    Did you find the front end parts you needed?

    Thanks for the information man. As far as the front end parts, do you mean the radiator and a/c condenser?

    FYI, on all newer cars, the low pressure fitting and high pressure fitting are two different sizes specifically to save against someone putting them on the wrong fitting. As such, the hose you have that you connect to the can of R-134a (or machine), should only fit on the low pressure side fitting. The high pressure side is a bigger fitting, so the coupler on your hose won't fit over it.
