Re: Running Warm

[Jim Altemose <jaltemoose@xxxxxxxxx>]

This radiator discussion reminds me of a question.  When I drove my 63
Polara 500 (383 4 barrel) 250 miles to Carlisle, the temp seemed good
on the highway but would over heat and boil over when I stopped and
turned off the engine.  Then I'd wait 1/2 hour for it to cool down and
top off with water and anti-freeze.  One the way back, when I stopped
for gas or 'other', I let the engine idle and that seemed better.

So, my guess is without the water circulating and fan running, the
block quickly heats and boils the water.  But you have to turn the
engine off some time.  Are there any proper procedures or guidelines
to long trips?  I want to be as nice to my engine as I can.

IR temp reader is in my future too.

As always, thanks.

It should move freely, but stop almost instantly, as if the clutch were filled with mashed potatoes. Start the engine. The fan should turn pretty briskly; almost as fast as the crank. Now use a rolled up newspaper to gently try and stop the fan. You should be able to when its cool. Throw away the ruined newspaper. Rev the engine, you should notice that the fan increases speed, but not proportionally to the crank speed. The clutch is full of viscous fluid, so the air friction on the fan starts overcoming the friction of the fluid in the clutch and it stops accelerating with the engine. The fan won't roar. Then let it get hot. You might have to drive it around some stop and go streets to get it to lock up the clutch. Now when you accelerate, you should hear the fan roaring a little louder. If you stop the car, shut off the engine, and try to spin the fan, it shouldn't move."
