I have an 86 420 sel. The A/C has a low charge. There is a hose that is leaking from the drier to the condenser. There is still R12 in the system. Has anyone converted their AC to a R134? I read that it does not cool as well. Or should I stay with R12? The shop quoted about to $200 to evac and charge plus additional labor to change the hose and the drier and the cost of R12.

The other option is spend money on the DIY kit from ACkit http://www.ackits.com/merchant2/merchant.mvc?Screen=PROD&Store_Code=AMA&Product_Code=DIY-STARTER1 to do the conversion to r134 and learn to do this well. With this forum, I know I can tackle this job. Let me know what you guys think. I plan to keep the car as long as possible. Everything else in the car is working great.

Thanks,

John
