[Rovernet] Where's the heat in my 3500S?

[Geoff McCarthy]

My 3500S has plenty of heat, but it is on-off.  The original valve was gone
when I bought the car. I replaced it with a functioning Jag valve, but that
valve does not have the feedback pipe.  I did by an original NOS Ranco valve
for an exorbitant price recently, but removing the heater to install it is
daunting...
I have not activated the A/C on my car, but all the bits are in place. I
plan a partial engine rebuild and will do it then.

Jim,   I've only run across one person with a 3500S who said the heater
worked well (I'm sure others will chime in to help with the problem).   My
heat has always been anemic and after I completely rebuilt the entire drive
train, in the process I had the heater core out for some minor repairs, but
never had it tested/recored (I rue the day).  With everything else cleaned
out and working perfectly, my suggestion is to find out if you heater core
is clogged/corroded/dysfunctional.


If the core is not a possible problem, I would love to hear from others
about any fixes because I can never drive mine in the winter because it is
too damn cold.

AC works fine, but it's the time of year when I need Heat!

        Didn't work last year so I replaced the vacuum valve with a good (?)
used one. At least the Rover owner who sold it to me thought it was good.
Didn't fix the problem. Recently, I took out the heat control switch (behind
the console) to make sure all the lines were connected: They were, though
some fit a  little loose. The letters on the vacuum hoses match up to the
diagram in the shop manual, as well.

        Any ideas what I should do next? Is there any way to run a test on
the vacuum valve to see if it's working?

        All suggestions welcome, since winter's knockin' on my Virginia
door!
