Re: [FWDLK] '59 runs a little hot...Higher flow water pump?

[Mike Apfelbeck <moparmike@xxxxxxxxxxxxxx>]

You shouldn't need to resort to an aftermarket part if your original pump
is in decent shape.
Make sure the hoses are in good condition and not collapsing, choking off
the flow.You should be running a fan shroud to ensure adequate air flow
thru the core, and the hood should should be sealed to the top of the
core support to keep the heated air from recirculating through the
radiator again. I wouldn't worry too much at 200 degrees as long as the
water stays in there, new cars run at least that hot.
