I am trying to recharge the refrigerant for the A/C but I have been unable to find what the pressures are supposed to be. What are the exact pressures supposed to be in order for it to work properly?
My car has an automatic transmission.
Hello. A/C pressure readings vary with the temperature. The A/C system should be charged by weight and not by pressure to fill it correctly. There should be a sticker located under the hood (either on the underside of the hood, radiator support or strut tower) that indicates the capacity of your A/C system - usually in ounces. You could also try finding the capacity in your owner’s manual. If you need help having this taken care of, a qualified pro from YourMechanic can come to your cat’s location to perform an AC recharge.
