Sure, the condenser is a likely possibility considering it was involved in a collision but don't forget that it's an older vehicle and multiple leaks is a very real possibility.
I would get it tested before replacing the condenser. Why spend money on something that may not completely fix the problem?
Take a few feet of small hose (gas line, vacuum line) and put one end to your ear and use the other end to listen for the leak. If it's that big a leak, it should be easy to find, no need for the dye.
It's probably the condenser. You might be able to see a wet spot where the leak is, because the oil in the system leaked out with the freon.
The condenser is likely to be in fault.You can test it Via Applying dye. What i will suggest you to show to some expert rather wasting time and money on it.
I noticed the other day I did not have A/C. I decided a couple days later to put freon in to see if it would get cold or leak out. I put about 3 cans in & it was cold. I turn off the car and hear a hissing noise coming from the whereabout of the top left handed side of my radiator. I did research and may believe it to be my condenser. About 5 months ago I did get in a accident causing me to rear end someone else. So it would be logical if it is the condenser the cheaper route. All my freon is out now. I still cant pin point the exact location of the leak but if I moved the radiator the noise would get soft or higher. What do you think? I have a 98 Toyota Corolla by the way.
