There are two types of condenser leakage for automotive air conditioners:
1) Leakage at the joint, most of which is leaking at the inlet and outlet of the condenser. The refrigerant can be recovered first, then the inlet and outlet pipes are removed, and the O-ring is checked for damage. If there is damage, replace it.
2) The condenser is cracked. It is generally recommended to change the parts directly. The condenser is still troublesome to repair. It requires professional flame brazing, and it is not a master's master who can't repair it. It is very troublesome. It is better to change a new one directly.
