Hi everyone,
I've been reading the archives for the past 2 days on the pros and cons of converting to 134A (or not). I've gleaned lots of info, but I still need details of installing new compressor and oil (mine has locked up-confirmed by a Mercedes mechanic), flushing the system, pulling a vacuum, charging an empty system. Do you know of a web site or book that could give a play by play of A/C reconstruction for the do it your selfer with lots of details? I was encouraged by the fact that both the local Autozone and Advance Parts Stores can supply all the parts, but I tend to need more details before I start pulling parts off.
Thanks--

Maybe one should be made
I do have access to a "Cooltech 700" in Richland. To easy dial in the specifications for 134 and oil. It will pump down, do a leak test then put the exact amounts in the system.

You must remember that most of the reading that you find will not be up to date.

To get you up to date consider the fact that R12 prices are coming down due to decreasing demand while 134 prices are going rapidly up. It just makes absolutely no sense whatsoever to convert a system from 12 to 134 with todays prices. You will spend more on adapter fittings and ester oil to make the conversion than you will spend on the difference between 12 and 134.

In my book, even if R12 were still five times the price I would NOT convert. Think about it, you will have so much in the compressor and time in the flushing than you will ever put in R12. Staying with R12, percentage wise will make almost no difference in your repair cost. THEN you will lose 15% of your cooling capacity.

It just makes no sense. Stay with R12.

Good luck,

Larry, you forgot to factor in the time and expense the average DIYer needs to spend procuring a license to buy r12, then the trouble to get the r12.

For most of us, it's very convenient to get r134 from the local auto supply house.
