Fan hits upper radiator hoses.

[Dave Castle]

Put a 59A in a 40 pickup, stock fan hits upper radiator hoses, fan will not adjust any lower, solution besides electric fan ?

[JSeery]

How much additional clearance do you need?

[Dave Castle]

2" would be close

Put a 40 crank hub/pulley and 40 fan on the engine and it will be fine.

Crank mounted fan clearance from the hoses will be fine, but cooling might not, because the crank turns slower than the bracket mounted fan which has a smaller pulley than the crank pulley, and the crank mounted fan is not centered on the radiator. The tips of the fan blades at the bottom are actually lower than the radiator core, and the distance between the fan and the core is greater than it should be for efficient cooling.

On my '41 I added a Speedway 2" shroud and fabricated a spacer to move the fan closer to the radiator. Solved the problem for 70 degree weather, but I have not had any hot weather since those changes to see if it really cures the overheating at idle. My flathead is 284 cubic inches and has high compression heads; a stock engine will not generate as much heat.

I would rather suffer an occasional overheat than go to an electric fan on what is supposed to be a classic hot rod, but that is just me.

So you're saying a fan 4" or so less in diameter than you have now would be OK? What the diameter now? Jack E/NJ

[Dave Castle]

16"

Use the 40 ford crank pulley and fan.

If the upper radiator nipples are high enough, then longer radiator hoses should work by arcing them clear of the blades. Jack E/NJ

Can you raise the radiator and lower the engine and use a smaller dia fan?

I have a 221 in a 38, run skip's water pump, no pressure cap, hood sides off, and no fan. If it heats up,shift to 2nd and run 25 mph and it cools down. I do not get caught in traffic jams. Run 15 mph or more and do not need a fan - just makes a lot of noise.

[JSeery]

Bill, reminds me of all the guff I was getting when I was discussing the fan issue on a 33. Several "old time" hot rodders were wanting to know why I would want to put a fan on it! There position seemed to be if you needed a fan you weren't driving fast enough.

JSeery: Fords do better moving than sitting. Fan just soaks up power. I had a 38 in the early 50's and did not run a fan so to use a smaller pulley on generator to charge battery - had sealed beam headlights. Chevys could attest to the performance of that 38!

Could you make a shaft for the fan with an offset? It might look something like a hand crank. Maybe a heavy piece of bar stock with the two shafts bored through it, high and low about 3" apart. It's too crappy out tonight to get up off the couch and go down to the shop and see if it looks feasible.

That was a very common practice in this part of the country in the 40s and 50s. On my 33 project I fab'ed an adapter to use a later pickup fan bracket.

GB: Imade this gizmo out of steel including the aluminum pulley set up. Also installed Griffin radiator and shroud plus 16 in flex fan. Been working fine since 1999. Perhaps something similar would work. If Dave can make a generator bracket out of steel, he could make it in such a way that the generator stays in its stock location but the lower part could be extended to be able to mount the fan carrier bracket lower down, thereby providing more room on top for the fan. Bob Drake also sells a new fan carrier pulley set up that , I bet, would also work as it's wide belt. The price is very reasonable considering what it cost me for the aluminum slug and the 2 industrial ball bearings inside the pulley. I turned down a steel bolt for the shaft. The bearing press on the shaft and fit inside the pulley. Give it a try.

Looks great! That would solve the problem nicely.

[Dave Castle]

Unlike a 8ba, the fan can not go down very much further on a 59A as it will hit the top of the distributor.

[19Fordy]

Oh no! I wonder just how much further down it could go? Even an inch would be a good start, plus a smaller fan. #4 post in this thread shows a 59A. I bet with a little engineering it would work.

try a shorter fan belt.
