Volvo 240 Air Conditioner Retrofit

Hi,

My air conditioner on my 87 Volvo 240 has stopped it's ability to keep
the car cool, so I have just had it retrofitted with the R134A. I was
warned that this does tend to leak gas. How long should this last
before needing the gas refilled? I drive about 250kms per week mostly
with the air conditioner on low.

Regards,

Han.

 

Don't know what to tell you about the leak warning. We had to replace our
760 compressor and had Volvo do the 134a retrofit nearly ten years ago, and
it hasn't had to be recharged since. But since yours stopped cooling, and
you didn't indicate a repair with the conversion, you must have a little
leak (too small to prevent the conversion.)

Time will tell how significant your leak is, and if it gets worse. Next
summer, if it doesn't cool well, time for service again. Should last all
season, anyway. (And that should be pretty much independent of how much you
use it, like a tire leak behaves.)

It should last years if not decades. Did you have all the O-rings and
rubber hoses replaced? If your system was dead before you had it
converted it's because it leaked somewhere.
