Samuel,
It is clear that this is more an issue of
capacity to cool or a restriction somewhere.
I think removing the thermostat would only affect the
low end and not the high end of the temperature range.
I have had no positive comments on uncle ron's
radiator flush so I am leaning to home remedys.
At this point I am thinking to isolate the radiator
and fill it with the following in three steps,
flushing in between. Alcohol, .2molar citric acid pH
2 amd .2molar E.D.T.A. pH11. I have tested these
chemicals with foil and the foil held up well enough.
If I mess up the radiator I figure I am headed there
anyway. Just need to figure a way to plug the lower
hose port. I will let the list know if this works.
regards gary

After reading Ben T's reply about rear heater
removal and coolant flowwhere he mentioned a physics
principle called Poiseuille's law, I didsome reading.
This law delves into how the size of the pipe
effectsthe volume of liquid flowing in a system. The
radius of the pipe is inthe equation raised to the 4th
power. I did some calculations and avery high
percentage of the coolant flow goes through the big
hoses tothe radiator, a small % to the heater system
hoses.
So, if you are getting engine temp reductions out of
coolant heatdissappated by the front heater core, that
tells you that something isstopping the flow either to
or through the radiator and it isn't doingits job.
Some other posts I read looking at that (by Dennis
Haynes)state that the flow to heater system isn't
controlled by thethermostat. So you problem could
start at the thermostat although Iremeber reading that
they usually break open, not closed.
Just some thoughts on this. So I think your idea that
the radiator isclogged in some way is a good starting
point.
