Model A water pump vs model B?
 

Hey guys! OK I'm trying to figure if the model B three bolt water pump along with a model C head in a model A block provides better cooling than the model A water pump! Thought's about the size of the impellers and others things! Any appreciation will be welcome!

Re: Model A water pump vs model B?
 

Definitely an enhancement. I have one and really like the added circulation.
I have to use a thermostat or it will push coolant out the overflow. My old pump wouldn't do that.
Best make sure your radiator flows well.
Good luck.

The radiator is #1 in determining cooling. You can pump all the water you want into the radiator but if it is not working properly makes no difference. If you have a cooling problem changing the pump will help little to none.

I fitted a B model head and water pump years ago made no difference to temp
mind it ran fine with thermostat before and after

Ok guys! Many thanks for the replies!
I think I can use a model A head and water pump! My C head have cracks and the stud holes were enlarged to 14.5 mm and in some the corrosion make a hole in there! And the pump is a 33-34 model! Not a model B 1932....

The 32 waterpump is functionaly the same as the A pump in where the pulleys line up, the later pumps are shorter
also when putting the A head on the B block there are 2 coolant holes in the block that the A head doesn't have that the head/gasket may not cover and should be plugged in the block when using the A head on the B block

Thanks! Kurt! I have a model A block with the C head! All the engine in parts! So recently I realize the pump is one in shorter.... Actually the C head have the two holes pluged with bronze... Maybe for use a model A gasket!
