How buttercup got her groove back

Recommended Posts

For the rear speaker switch, I used Lamar's template to get in the ball-park, but adjusted it slightly...  I measured and eye-ball confirmed to where it is even in height with the wiper control, and the same distance as is spaced between the headlight switch and wiper control.   Basically, balancing the three controls.  That worked visually for me, and is easy to see behind the wheel.  I had to grit my teeth while putting a drill to the dash, but more chrome and luxury is always good!!

Well I pulled the water pump and unfortunately the leak is at the weep hole. I was really hoping I'd just messed up a gasket.  I'll send it to flow killer for a fancy impeller.  In the man time I'm going to flush the fuel tank again. 😳😜

Some people say Flowkooler is a gimmick, but the design is supposed to be high flow, minimal cavitation. If the school labs translate to cooling in a cylinder head, the best cooling is achieved when the flow is most turbulent, AKA going faster. You'll have to let us know how it performs, as I am wanting to do the same thing.

Too bad we can't figure out a way to cool the nailhead like Chevy did with their 5.7 liter LT1.  Reverse flow has the water enter the heads first where the coolant is needed most.  It then flows through the block and back into the radiator.

Maybe there is a impeller that would fit or could be created for the original housing that move the water in opposite direction.

This does not compute. Water will need to slow so it can pick up the heat and carry it off as I understand it.  Is faster flow meaning moving more coolant than the standard impeller?  It appears I start outrun my water pump at speeds if 65-75 mph during very hot summer days.  I get a bit miffed when I see Pontiac of the same years that have a box from the grill to the radiator. The airflow has nowhere to go but through the radiator.  Our Buicks the airflow dances around and goes where it likes.

I don't know about the water pump but as for getting air through the radiator..... the 5 bladed fan sucks things through the grille and up against the radiator it moves so much air

Without getting too much into heat transfer stuff, there is some degree of dwell time but from every lab test I've conducted on campus with cross-flow heat exchangers, faster flow of coolant through the hot stuff always equals better heat transfer. Think of it like this. The coolant contacts the surface of the hot stuff only on the outside of the flow volume. The more turbulent the flow, the more it "mixes" the flow so it constantly takes the fluid in contact with the outside and swaps places with the inside colder stream, until it reaches a saturation temperature if given enough time to dwell.

Think about how much 'cooler' you feel when it's 30° F outside and there's a 25 mph north wind compared to when it's 30° F outside and there's no wind.  

 

I don't know about the 50s era nailheads but on the 63 - 65 Rivieras with which I'm familiar, the A/C cars have an impeller with more blades than the non A/C cars, they have a 5 blade fan rather than a 4 blade fan, they have a shroud on the back of the radiator, and the radiator is sealed to the core support.  All to move the cooling factor (air in this case) faster in order to absorb more heat.

 

If you were to run a serpentine belt on the present setup, you would in essence reverse the flow of the coolant.  But that would also mean that you'd be pumping water into the bottom of the radiator. That ain't gonna work.

Metal does not experience the sensation of hot and cold as we humans do.    Reverse the hoses to the radiator!  Just a bit of replumbing.

I know that, I was just trying to make a point.  Metal doesn't have sweat to be evaporated to cause "wind chill."  Water on the pond in 34 degree weather will not freeze even if the wind chill is -30 degrees F. 😎
