RE: Heater Core and overheat

[Willard Edison <waedison1@xxxxxxxxxxx>]

Paul and I had different solutions for overheating back in the sixties.  If
I was day-racing, (Nevada heat, 5,000 foot elevation) and was showing signs
of overheating, I'd turn the heat control to high and the heater fan to
high, which putlled a lot of heat out of the system. After all, the heater
core is just a mini-radiator. On a few occasons, I pulled the thermostat
altogther, which upped the coolant flow and did not have any adverse
consequences. Sometimes uncomfortable,,,,but it worked.

I'll offer an opinion here.  It would seem that while taking the heater core
out of the loop will lessen the total amount of coolant in the system, it
doesn't seem like it would make that much difference in the scheme of things
if everything else is in good condition.  Especially since w're not seeing
summer time like temps yet.  Not sure what part of the globe you call home.
But around here it has only reached @ 80 degrees so far.  
Back in the day (forgive the old timer moment here)I had a '61 Plymouth in
which was installed a shut off valve to the heater core.  In the summer time
I would close this valve to keep the hot coolant from flowing through the
core.  The idea being it would help to keep the interior temps down in a
non-a/c car.  It never affected the engine operating temps.  
I think all of the suggestions given here are good ones.  Basically they all
lead to making sure all of the components are operating at peak efficiency.
With all this in mind I have my own over heating issue as noted in an
earleir post.  So I should probably follow some of the advice offered here
as well.  The first thing should probably be to have the radiator flow
tested.
