The sealant is a low-cost, quick-fix solution for sealing tiny leaks in the air conditioning system. R-134a Super Seal may be found at practically any car parts store. Turn off the engine and crank up the AC and fan to maximum settings. Connect a hose to the Super Seal can through the hose coupler and the low-pressure port. After the liquid has been transferred, replenish the system with R-134a refrigerant. Run the air conditioner for at least 15 minutes to allow the Super Seal to distribute throughout the system.

2. Work On The Evaporator

Work On The Evaporator

There is no Super Seal that can repair an evaporator leak. You must either repair it or replace it entirely. To repair pinhole-sized ruptures, cut and crimp the tube. A little soldering can help in this situation. When the puncture(s) is/are larger, the only solution is to replace the evaporator. To instal the evaporator, you must first remove the dashboard. You should also vacuum the system before charging it.

Conclusion

Repairing a leaking car air conditioning system is a do-it-yourself project. Many leaks can be repaired using a can of refrigerant stop leak and a hose to introduce it into the system. For significant leaks, the faulty component must be replaced and the refrigerant reintroduced. If you have a difficult-to-find leak, a dye can be injected into the A/C system to help locate it. There are also refrigerant leak detectors that can detect a leak and beep loudly when it gets close to a leaking area. A low-cost leak detector is an ideal alternative because it is quick and simple to use.
