Not sure why anyone needs to convert to R134. R12 is getting cheap these days as fewer cars are using it. I have 4 cans on Ebay for $80.

R134 is the only alternative to R12. Anything else will be a gamble and no shop would knowingly touch your system with a recovery machine if they knew you had put some sort of snake oil in it.

Before anyone says Freeze12.... Freeze12 is 80% R134 so it's not a direct drop in as it's 80% R134 so it won't mix with the oil so R134 is the only real alternative.

I have disconnected my A/C after the bearings on the tensioner went out. Getting that part was expensive. Now I am going to put the belt back on and take it to get recharged. So, after over a year, the A/C compressor is about to be connected to a belt again. Should I have the shop connect the belt or will it be fine to put it on myself and drive it in? I just paid $200 for a little pulley so I want to try and save myself some $$$$.

Any thoughts...espeacilly from Mr. Pool....lol...you probably don't remember me, but you serviced my little BMW 325i a long time ago
