can someone tell me where the low side service port is, so i can recharge my a/c. thanks
How about a 2002 Envoy XL. Same place as posted before?year make model:undecided
Find the compressor. You should be able to and if you can't find the compressor.. turn on truck, a/c off, have someone go inside and turn the a/c on and look to see which pully makes the noise of the clutch engaging.Found another black cap on the silver round cylinder on back left engine compartment (accumulator)?
Then the one (black cap) that is in the line on front left of rad area (line is only about index finger thick).
Well I would hope he's getting the mini 134a tank and guage combo from advanced or auto zone.You do have the guage set so that you do not overcharge the system and you do know what you are doing? 134A boils around 45 below 0 (depending on the pressure) and can give nasty frostbite burns.
