A/C Recharge
I have a 1991 964 and every 2 years or so the R12 freon goes away.
It's way to expensive to recharge anymore and there hasn't been a leak detected in the past. My shop says that to go 134 I should change the drier. 134 seems less effective and corrosive. I was told by a friend about Freeze 12 and Autofrost as alternatives which he has used in his vintage muscle cars without a problem. And it seems to be cheap!! Thought or experiences?? Thx... Mark
