[Chevelle-list] Is there really a "high flow water pump?"

[Dean Vandergriff]

I'm coming into this one a little late, but are you boiling over or just
seeing elevated temps on the gauge?   If you're not boiling over I
wouldn't worry too much.    My 454 with flex fan, & no shroud ran
consistently at 180 idling would jump up to 200 pretty quickly, but it
never boiled over.    If you check your gauge 15 minutes after you shut
the car off you'll likely be scared by the temp that you see & that
happens every time you shut it off.    But again, if it's not puking
coolant all over the ground don't sweat it too much.

 

Just my .02, or is that .06 worth at today's rates  :-)

A 160 thermostat won't fix anything.  It's overheating because the temp
of the coolant is higher than that of the thermostat at all times
menaing it's staying open and coolant is not staying in the radiator to
cool down.  There is a such thing as running too cold.  Flex fans are
junk...period.  They flow LESS air then the RPMs are in the mid range.
You should be running a 180-185 thermostat in a 402 along with a 19" 7
blade clutch fan and the correct fan shroud.  GM engineered this for a
reason...it works.  I have a stock cooling system on my 70 SS 454 and
never have overheating problems with it.  Another thing that comes into
play in this situation that alot of people don't realize is the size of
the water pump pulley.  Does it have the correct one on it?  Another
water pump won't fix anything if the pulley is the problem.

	Dropping the temp of your thermostat will not affect an
overheating problem.

		Test show that if you have the proper capacity radiator
that copper vs aluminum is a break even.

		Go to a 160 thermostat, flush the block, make sure your
hoses are not collapsing inside (do not take out that bottom spring).
Test the pressure of your radiator cap that's important for your over
flow system.  If you have a clutch fan replace with an aluminum flex
fan. Make sure your fan blades come to the back lip of your shroud.

		Hello all...I have a 71 SS 402 and I am still fighting
the summer time over-heat monster. I plan to order an aluminum radiator
soon but I remember someone telling me that the so-called "high flow"
water pumps are no better than a standard water pump. My overheating
seems to really occur at idle (stop light, traffic, etc.). So here is
the question: Has anyone really found a high-flow water pump for my car
and if so, where can i get it and how much? Also, do you think the
aluminum radiator will help?
		 
		Thanks,
		tbDallas
