water pumps

[Kim K Kaiser]

my pump has gone out again in 63, 390. I dont know why, either too tight a belt or something else, been 2 or three since rebuild and 13k miles.. it was a gates unit.  it seems for a while the cordone unit was the only one out there with the enclosed impeller but apparently, they are no longer available anywhere, even there company site doesn't list them.  While searching, I found that rock auto now has a supplier with the enclosed impeller,  https://www.usmotorworks.com/catalog/ through rock auto.. may give it a try,, anyway, its just for info as the enclosed impeller has been hard to come by, not sure it makes a difference, but I think its what was on the original motors..

The enclosed impeller is what was on the original water pumps.  What are you putting in your radiator?  The coolant acts as a lubricant for the water pump.

I used on of the 50/50 antifreeze  products out there,
