Hi All,
	Has anyone upgraded to the six vane water pumps offered by, among others, Flying Dutchman Water Pumps?  If so, is your experience that the upgrade decreases over heating?
	Thanks.

Bob,

I did on my 63 TR4 a number of years ago when the original seized. To be 
honest, I have not seen any difference in operating temp. I have the 
original pump on my 72 and it runs on the cool side compared to my 3 and 4.
