Which port do I hook up ac freon to charge my ac
The one on the accumulator. The accumulator is the large shiny silver can looking thing on the passenger's side of the engine compartment. You'll see the service port on it. If it has 2 service ports it's an aftermarket one. No problem, just hook up to the one that your R134a hose will snap onto. HTH. -Jim
its also the hose that goes into the passanger comp.....
its not #2 but top left of center..for a quick look...
