Hi, I'm at the mercy of the mechanic. I have a leak at the lower fitting of the condenser. First he said he replaced the "o-ring".
I took the car home but noticed the same leaking the next day. Then he replaced the condenser. I can see that the condenser is black, different than before. I took the car home. Next day, the same leak. Please look at the picture and advise me what the mechanic can do. I already paid a lot of money to fix the leak you see in the picture, but no success. I don't want to "play mechanic" because I am not a mechanic. I need to try to work with him because I already paid a lot of money. The leak that you see is refrigerant oil with green dye. It is not antifreeze because that is yellow in my car.
Most likely is a sealing washer application- hopefully, your mechanic knows the difference between a sealing washer and an o-ring.....bit I've seen worse. If the surfaces are flat, definitely a sealing washer- would need to see the innards to determine if o-ring- if o-ring, he probably is using an undersized diameter one- needs to get in his arsenal and pick out the proper sized o-ring.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
I cannot tell much from the picture regarding what type of connector, seal, and/or retaining system is being used here.
Your mechanic probably wanted just the o-ring to be the fix, but it wasn't, and then he decided best to replaced the condenser. Are you sure its leaking? Could some of the refrigerant oil with dye, have been used as o-ring or thread lube? Might be the wrong seal all along; or may be a bad fitting, may need to replace that next.
