There’s been a lot of buzz about the increased cooling properties (over the earlier models) of the ’91-’92 240’s with factory equipped R12. Hearing this I am eager to get my Brick’s system working once again. I drive a 1992 245 that has an R12 A/C system on its last legs. The compressor is leaking, and the seals have all but failed and leaks abound. That said the other components of the system are intact and functioning as they should.

My questions are as follows:

1) Which conversion kit do I purchase, where do I buy it, and which components does this kit contain to convert to R134a?
2) Is there a book or manual (such as the Bentley) that will explain in great detail how this specific AC system works?
3) Is there a book on A/C conversions or function, in general, worth reading?

I plan to take my time and do this repair as much as I can out of my own driveway, following instructions to the “T”. I want to do the job right and once, so I am not averse to spending money to buy the best parts for the job.

Thanks in advance.
