Been following this thread.  When I lived in Los Angeles I had a pusher fan
as I commuted into downtown. I had a switch control. I removed it when I
moved to Oregon.  I recently installed a more powerful one for my Conclave
trip with thermostat and switch control.  It helped.  I just installed an
air shovel and it has improved airflow a lot. Car stayed cool on a 250
drive and stop and go freeway traffic.

Kees -

Living in hot and tropical climates like I have, I can confirm that using
cooler thermostats helps a great deal to reduce heat spikes in traffic, as
there is significantly less heat energy stored in the coolant at 165F vs
180F.  That combined with a well sorted system will be sufficient to give
you a few more minutes at idle than if you were running a 180 or 190F
thermostat on a very hot day.

You are correct it technically will not prevent overheating, but it will
postpone it long enough until you get driving again.

Best,

Alan

What is the down side of running a 165 degree thermostat?  Is your engine
not running at optimum efficiency?  I have been led to believe that an
engine's optimum running temperature is somewhere around 185 - 190 degrees.

Honestly I have never found a downside to it.  Actually my experience is at
190 some stuff gets loose on the car, so at 165 stuff seems to run better.
180 works okay but I prefer to have a wide mouth thermostat like the
Waller, then that's okay too.

"Overheating" is an imprecise term and so long as the rad does not boil
over and/or the carbs go into vapor lock the fact that the indicated temp
is at or slightly above 212 is not a conversation stopper.
For those really challenging situations where traffic is stop and go, etc.
I turn on the auxiliary fan ASAP and place some duct tape over the temp
gauge so I will not constantly look at it.  If things get drastic the car
will tell you....
