When I converted my AC System on my 300D over to 134 two years ago, I changed the Receiver Drier. I am using inexpensive Pep Boys compressors which have to be replaced every two years anyway. I am once agian in the middel of replacing the AC Compressor

(1) Should I change the Receiver Driver again? These compressors only last two years.

(2) The system is open to the Atmosphere as of this moment--I ran out of time tonite changing the compressor. Will this deplete the Dessicant?

(3) What factors affect Receiver Drier Dessicant life?

(4) Whats the lowdown on moisture in the System? I know it exacerbates bearing/compressor wear..

Changing Receiver Drier critical to AC success? 1985 300D
