rebuilding a/c after accident

Year: 1991
Make: Toyota
Model: 4Runner
Engine Size: 3.0
Refrigerant Type: R12
Country of Origin: United States

...I was is front-end front bumper basically took out my condensor/fan/receiver.

I was able to pull off the condensor/fan/receiver still connected to each together from a donor vehicle. On the recommendation of the yard, I will be getting a new receiver.

Here are my concerns:

- Is there a way to decontaminate the used condensor
- I'm pretty sure the 'freon' is out (cut line to btw condensor and receiver), but how do I make SURE
- Once there anyway I can check for leaks? is there a DIY dye I can add?
- Once there are no leaks, I plan on converting it from freon. Can I do this myself now since the freon is out?
- Do I need to purge the R12 oil and can I do this myself and on the vehicle (compressor)?

note prior to the accident there A/C was working fine.

My recommendation is going to be to purchase a new drier and condenser. You do not know the condition of the used one you are buying and if there is debris in the condenser it will destroy your system and you will have to buy all new parts. The fan you could take off of the donor vehicle but when it comes to parts like that I would not chance putting on used. If you are set on using that condenser you are going to want to flush it to make sure off the old oil is out of it. How long has the system on your vehicle been open? I would recommend flushing the line's and evaporator as well and starting with a fresh oil charge and clean components. If you want to convert to 134a you can but it will hinder the cooling slightly. I would recommend getting it all cleaned out and put back together and pulling it into a good vacuum for at least 30 minutes and then getting it charged with the exact amount of R12.
