Yes, it came from the factory with R12. R12 was used up until late 1995. I suggest you convert it over to R134.

It came from the factory with R12. Due to the cost of R12 I suggest you have it converted to run on R134. Have the leak fixed and convert it to R134 and save yourself some big money. R12 is no longer in production, and is very, very, expensive.
If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
