Subject: Re: Heaters(again)
hi there,
I just did this to my bus, a '73 camper. this is what i saw
and talked with others about.
take off the flexible hose that goes from the blower motor in the
engine compartment, to the heater boxes and look for holes there. if
you find some???? could possibley use muffler repair tape to hold it
for a while, but rust is...
under the car the heater boxes on each side go into these plastic
acordian cylinders. these are mufflers that help keep engine noise from
travelling up front. take them off and examine them for holes and
check and make sure the paper inside has not peeled off. if so use
chicken wire to force it back against the insides so it is not
clogged. now look at your heater boxes where the muffler attatched.
you can see the flap (and heater cable) that open up. make sure they
open and close.
these accordians attatch to a "Y" then to the tube that goes to the
front. take off any existing insulation and look for holes and rust.
use sand paper and rustoleum on the rust and jb weld (messy stuff) or
RTV and aluminum cans to patch the holes.
up twords the front there is another "y"-ish section (on my bus at
least). there is another flap and heater cable hear. when open it
allows heat to travel to the back of the bus. make sure it opens and
closes. (it was easy for me, there was a huge section of pipe
missing).
the tube then twists its way to the front, and up inside. (take a look
at what all the pedals do under the bus when you press, the clutch
too).
take the cardboard panels off under the dash on the inside of the
nose. be careful of the wires. here you can see how it selects
between heater foot ducts and defrost. check to make sure the flap
works and no holes.
insulate the pipe under the bus, (bob's foam and wax paper or pipe
insulation from a hardware store). now fix the door and window
seals:)

I think it was an option, mine does not have one. and yes, you can
replace one. the cheapest way is to go to a marine supply store and
buy an inline fan with variable speed. you can get them from jc
whitney, but i understand they cost twice as much.
hope it helps. take care!
