Where is the low pressure end of the A/C system on a 2002 Intrepid?

Question

I am trying to add refrigerant to my system and cannot find where to attach the R134 hose. Anyone done this before?

Answer 1

Without getting technical. Follow the larger pipe/hose. This is your low pressure side. Start at the compressor because unless I am mistaken it is on the fire wall partially hidden by the engine. You will find a what looks like a round cylinder somewhere on the line. The low pressure connector should be somewhere close to the cylinder. The quick connect will most likely have a plastic cap covering it.
If you still can't find it you might have to go to a parts house and get a Haynes repair manual for your car.

Answer 2

OK look at the condenser that sits in front of the radiator and looks just like a radiator, this is the high side and will have a metal line that runs to the evapator under your dash, It is high pressure running into the evapator and low pressure running out to the compressor, there will be service ports on both these lines. you may need to have the compressor engaged to add r134a in the low side or you will only be able to add enough until the can and system equalize. you may have to jump yhe low pressure switch

Answer 3

just remember low side sucks the big 1 follow the largest a/c line and look for the schrader valve or charging port
