Re: [FWDLK] '59 runs a little hot...Higher flow water pump?

That makes sense actually.

In traffic you move slower and generally your engine is at a lower RPM.  So
the fan pulls less air through the radiator.   So it runs hotter.  Put an
electric fan on, it runs the same all the time regardless of RPM.  So you'd
get more airflow in traffic and run cooler.

My rat car the fan actually isn't working in.  It's been cold and I didnt
feel like changing it.  The car runs cooler when I go fast with it b/c the
air is blowing into the radiator.  If it gets too hot, I turn the heater fan
on full blast.  Sitting at idle made the hot light come on one day when it
was below zero out.  Which kind of proves that airflow is what makes the
difference in coolant temp.

Putting more coolant through the radiator might actually hurt more than
help - it would give the coolant less of a chance to exchange the heat and
be cooler when it enters the block.

I don't know what to tell you, Lou. My 60 is the same way--if I sit in
traffic too long it gets hot. My 57 Studebaker used to do the same thing
until I put an electric fan in. Now it always stays right between 160-180.
Maybe you could do that.

  Last year, I had my radiator recored (3 or 4 row...can remember which),
and upgraded to a 6 blade fan, but the temp gauge starts to creep up pretty
high and pretty quickly on a hot day in slow traffic.  I hesitate to go from
a 180 to a 160 degree thermostat.  The shop used a laser pointing temp gauge
which shows that the thermostat housing area is indeed staying right around
180 degrees, but when you point the thing a little farther back, and on the
intake, and areas near the temp sender, sure enough the temp is in the
200's.  Dunno what it should be in those areas, but it just  makes
uncomfortable thinking that it could be running hot.

  Timing is OK, new cap, etc.   I see that Summit Racing sells  "FlowKooler
Mechanical Water Pumps."  Anyone have any experience with these?  Wondering
if they work and are really any good.  Here is the narrative from

http://store.summitracing.com/product.asp?d=5&s=614&p=293&searchtype=ecat

  Get 30 percent extra coolant flow.
  FlowKooler water pumps solve low-speed heating problems by doubling the
water flow rate at low RPM and idle. At 3,500 RPM the flow rate returns to
normal to prevent too much water flow at high speed and they last longer
than a stock replacement. These pumps use a specially designed steel plate
on the impeller that traps water, eliminates cavitation, increases flow, and
reduces engine temperatures.
