Yeah, I knew about the downside to R134a.� They also say it does not cool as well as other refrigerants, but that was part of my "nothing to lose" rationale.

The hose process is pretty well documented in a couple of Samba threads.� One guy did his whole '87 Westy system (wish it had been mine) by removing all hoses and having new barrier hose with the old connections made up, then reinstalled.� Inspirational, and I think the hose work cost was about $300, plus whatever else he did.� Sure beats the two grand estimates for repair reported by me and some others.

As I understand it, if you convert to R134a refrigerant the system will 
leak because the 134a molecules are smaller and find their way through 
the hoses.It's a slow process and if all the connections are up to date 
with the right kind of seals - an annual refill is about all you will 
need. The only way around that problem is to replaces the hoses - which 
is rather pricey.

> My 86 comes with AC but the belt is not there... I presume since AC is not a necessity here in Vancouver BC that it was left unrepaired. Any idea if the AC in a Vanagon is something prone to break and not worth the expenses? What is the reputation of the AC system in the 1986-1991vanagons?
