Is A/C Conversion to R134a Possible?
The A/C in my '79 240D has always been anemic and I suspect there is a leak somewhere since it's never really produced frigid air. I'm not expecting polar blasts from this completely stock, OEM air conditioning system powered by a 2400cc diesel engine, but would expect air cooler than the outside air!
That said, I'm seriously considering taking the car to a dedicated A/C Shop in town and having them 'overhaul' the system - check for leaks, make repairs, clean out/flush the system, etc. I expect them to find a leak or two; hopefully nothing too expensive to fix.
Question - With all this work being done, is it possible to convert the existing OEM system to R134a at the same time?
I would seriously consider this as A) R134a is more environmentally friendly than R12 (though still not perfect) and, B) I can legally work on the system (recharge, etc.) in the future as a DIY mechanic. (There are restrictions for discharge of R12, for example.)
Cheers,
Jeff
