where do i need to put the feoron to reboost my AC, my radiator had to be replace and when they took the ac condenser off all feoron came out and, now even though I try to reboost it with the feoron my ac is still ot working. Was working before I hit a dog, my radiator had to be replaced and ac consender fixed, it was tested and working. Maybe i didnt do it right.
Thank You for writing into AskPatty. To address your concern your R-134A should be added to your low side pressure line, typically this is marked by a blue cap with a "L" on it. There are many auto parts stores that carry a prepackaged kit with a hose and a pressure gauge included, be sure to follow the directions on the car. It is a simple process that can be performed by most car owners. If you need further assistance I would contact your repair shop that replaced your radiator, they may be able to inject a dye if a leak is present.
It would be best to have a technician add freon/refrigerant to your system. If the system was opened up, because you replaced the condenser, then they need to run a vacuum on the system before you add freon.
It's possible that there is a leak somewhere else as well. When they replaced the condenser they should have re-charged the system then. If they did and the a/c isn't working, you should take it back to the shop that did the work.
