I just tried an after market pump on my 3 main 1600
(R-01782). Indeed the bolt pattern was a smaller
diameter than my pully, and the threads are metric I
believe. So, I'm looking again. The housing was
identical. The last time I changed pumps, I had to
drill out a hole in my 4 bladed fan to accomodate the
longer shaft than NOS pump.
Will the H-20 pump work for me?
