Hello All,

Finally managed to get the heating system back together in my 1981
vintage 245 wagon.  I had to replace the fan motor, heater core, and
control valve.  After FCP supplied the correct valve kit (i received the
wrong one first), i installed it, replaced the heater, and refilled the
system with glycol.  BIG SURPRISE !!  The valve leaked badly, and i
could not even restart the engine.  To solve the problem i put in a VW
Golf/Rabbit heater valve with a modified actuating arm (much shorter).
The heating system is back together, no leaks (yet), and the heater runs
nice and hot  Now i can reassemble the center console and dash.

Why a VW valve ?  It costs _much_ less than the ScanTech product, and is
probably not as leak prone.  You can see the retrofit photos at
<http://contrex-consulting.ca/245dl_1981_restoration.html>, Section
2.2.3.  By the way, the old style Volvo valve is _not_ repairable.  The
rubber membrane at the top develops pin holes, and it is impossible to
replace it, or seal it.  I tried very hard, but to no avail.

Hi John,

Your report on your handiwork, available at the website you supplied:

http://contrex-consulting.ca/245dl_1981_restoration.html

is absolutely amazing.  I wonder if other NG readers missed it, failing to
go to the website.......... The subject line of your post doesn't do it
justice.
You've done a tremendous amount of work, but what is perhaps more impressive
is the intimate detailed manner in which you recordrd it.  I learned a lot!
May be in the year 2017 our '93 245 will be in need of some these
repairs...............

Well done John!
Andy I.

Andy,

Thanks for your kind comments.  At least a couple of people have looked
at the web pages judging from my access log on the server (OpenBSD 3.6,
free, stable, secure, and available on CD from Calgary, AB).

The issue of a heater valve replacement is, in fact, significant.  A
leaking valve _must_ be replaced, especially when it is located in the
passenger compartment of the vehicle.  You could plug off the heater
hoses, and have no heat at all, or install a tube instead of a valve,
and have full heat all the times.  Neither "solution" is acceptable.
One really needs a proper valve that fits, and does _not_ leak!

I made the notes and photos (now that i have a small digital camera) for
my own use.  It helps to record what i did, so that i remember for the
next time.  The HTML file is easy to write, and makes a good "notebook".
 Plus, if someone else can benefit from my experience, so much the better.

When i refurbished the front struts, and the in-tank fuel pump i did not
yet have the digital camera.  It would have been nice to have photos of
those repairs as well.  I am not finished yet.  Perhaps by spring time
the car will be ready so that i can get the plates plus insurance for
it.  This wagon is for my wife.  By the way, i noticed that you have a
shaw.ca user ID.  You can reach me off-line at
c..o..n..t..r..e..x..AT..s..h..a..w...c..a.  I am in BC, close to Victoria.

I too have benefitted from John's experience and documentation. There
really is a lot of that sort of thing out there- folks who start some
hobby or some process, document it, and post it on the net. I have
done a few myself, although not Volvo related. It is amazing at the
reach such efforts can have. I am in California and I got a letter
from a fellow in England thanking me for one of my how-to sites,
telling me how much effort and trouble it saved him. Moveable type,
television, and the Internet... amazing stuff all.

And, John- I can't primise when, or even "if," as I have other
prijects going, but if I can, when I do my struts I will try to take a
lot of pics and send them off to you. In the meantime, don't turn down
any other offers for the same. BTW- the "other project" at the moment
is the used 30 foot (9.25 meters) motorhome we brought home last
night!!!   :-)

I never thought I would own a vehicle with a bathroom, kitchen, couch,
and queen size bed in it!!!!!   ;-)
