A suggestion: before taking the hoses apart under the dash. Disconnect
the lines inside the engine compartment. Then with a cheap siphon
apparatus; you can pull most of the liquid from the fan unit and hoses.
(It worked in my dreams - mine was bone dry because the valve was turned
off and everything had leaked out before I got it.)

Subject: TR3 heater fan
Item Subject: cc:Mail Text
I recently resuscitated the heater in my TR3a, which I
think is the
same as the TR3b. It needed the bushings lubricated, and
the only way
to get at them, unfortunately, is difficult. The heater
comes out as
an assembly, and you'll have to drain your antifreeze
first; even then
you'll likely spill some in the passenger compartment.
Watch for a stud at the very top - in the engine
compartment its nut
secures a clip that holds down the brake line. It's right
in the
centre in front of the vent. That nut has to come off
before the
assembly will drop.
I hooked up a battery charger directly to the fan motor and
it didn't
turn, so then added some penetrating oil and turned the fan
by hand.
(By now you'll have taken off the three clips that hold the
fan
assembly into the core.) Once it got moving a bit I
"flushed" the
penetrating oil out with 3 in 1 oil, at the recommendation
of a fellow
lister who suggested that the penetrating oil would not be
a good
long-term lubricant. I left it running for about 45 minutes
to be sure
all was well, and over this time the motor speed gradually
increased.
This is a great time to flush out the core. Mine had so
much sludge I
flushed it for 20 minutes before the water came out clear!
Also, those
original ribbed hoses were rotten as can be.
Hope this is clear, and helps. Feel free to contact me if
you'd like
further clarification.

Jim Wallace

Subject: heater
I am trying to determine why my heater on my TR3b doesn"t
work. The
fan motor does not work and I wonder if anyone can lead me
in the
right direction before I disassemble the whole system.
The cooling
system is connected correctly, but upon turning the dash
heat knob
clockwise, no action occurs.
I suspect a wiring or frozen fan motor. Any suggestions?
