Re: 1937 water pump removal

Henry, that is a small port hole to allow for some coolant circulation until the thermostat starts to open.

It looks like the conversion to the later sealed bearing pump used in pressurized systems from 1938 forward was done in a good workmanlike manner.

Also, the installation of the alternator was well done with changing the water pump pulley and the vibration damper pulley to accommodate the narrower drive belt used on the alternator.

All-in-all, I think these modifications were done properly.

It is common practice with these Packards to have to jack-up the front of an engine to access the lower water pump cap screws due to an aged and sagging motor mount. This would be a good time to install a new one. Stainless steel cap screws and copper washers with a good thread sealer for those that screw into a water jacket would be a good idea too.

Please keep us appraised of your progress in re-juvinating (sp.?) your grandfather's Packard.

Give Feltz my best.
