I was told by a friend that he thinks I have to upgrade my water pump to one that has more flow if I install a 4 core radiator. Is this true?

Your friend is a Ford guy aint he... No diff in water pumps.

I have never heard of needing a water pump upgrade for a 4 core radiator, but if you do change your water pump out at some time I recommend OEM GM or AC Delco only.

I put an aluminum hi flow hi pressure pump and all it did was hold the the thermostat closed. Changed back to a parts store pump and all was fixed...

I run stock water pumps on all my 4 core radiators (chevys and pontiacs currently) without issue.

Stock pump and radiator in the Ford, so I can't comment on that Esbstuff
