I tried it in my 1997 Jetta since it had a small leak
in the evaporator and it worked for about a month. I
added a second can, didn't work at all. I bought a new
evaporator, now I'm waiting for a long weekend to pull
the dash and replace it.

Replacing the o-rings in a Vanagon isn't that hard,
the only ones that are a pain are the ones on the
expansion valve and evaporator which require
disassembly of the rear housing.

If your hoses are leaking, I would recommend replacing
them with the barrier type hoses, especially if you
are converting to R-134A.

If you haven't ever dropped the rear housing for
cleaning and resealing, you probably should. It will
make a big different in the amount of air pushed
through the system.

Good luck,
