Hi!  I'm hoping someone out there can shed some light on my problem:

My '85 Vanagon overheated the other day, and became a sauna of steam smelling
strongly of coolant.   The steam came from the secondary heater vent under
the rear seat.  I'm guessing it's the heater core.  I can't emphasize how
much steam there was...it poured out of the open windows for at least 10
minutes after shutdown.

Anyway - it is in the shop now.   Not my regular shop, but these guys have
worked on the van before.   They called today and told me that it was going
to take longer than expected because (and here is my concern) they need to
take out the seats and pull back the carpeting to get to where the steam is
coming in.

I realize that the Vanagon is engineered like nothing else, but...I'm very
nervous about this.  It just seems to me there's got to be a better way.  Has
anyone else experienced this?  If so, I'd appreciate any light you can shed!

Thanks so much!
Lauren
