Thank you but I’m not trying to install a flex fan. I am taking one out and putting in a stock fan that cars with factory A/C used. The problem is that the hub on the pump aligns both pulleys but it does not protrude through them to align the fan. Aligning only by the four screws seems a disaster in the making.

As for the flex fan that was removed, it has an adapter/spacer that did align it with a nub that went into the hole in the pulleys and one on the other end that went into the fan itself.

No such plug existed since radios were not typically removed. The radio delete plate was for vehicles not ordered with a radio which meant that they never had an antenna installed.

I got the proper fan back in but I am very leery or it not having any alignment from the hub on the pump and every core I have, most of which came from power steering cars, is the same. Can this be normal?

With a manual transmission it’s easy but with an Ultramatic, the cooler IS the lower hose and it’s mounted to the engine with a short straight hose to the water pump and no room for movement, and a 90 degree hose at the bottom to the radiator which also has little room to move. The shop manual simply says to remove the lower radiator hose and I can find nothing specific to the cooler! Anyway, I finally managed to get it out with some prying.

What’s odd is that when I used to work on Packards regularly I had no manuals and never needed them but now it seems that everything I do requires looking it up! I guess that’s the price for waiting so long to work on these cars.

As for corrosion, there is not much but the cooling system does need a good flushing. I’m not planning on driving this car anywhere so just getting it moving under its own power is a good thing!

What is the trick for removing the transmission cooler? It seems that the studs to which it mounts are too long to allow it to slide off in order to pull the upper hose free.

I am also getting rid of the noisy flex fan and instead am installing a 20” factory A/C fan. I had to fight to get the lower radiator hose disconnected and don’t recall it being so difficult when I did it before!

The radiator was also attached directly to the frame without the benefit of the rubber pads that I recall it should have.

Now that it’s apart and the flex fan removed, I can’t see what it is that is supposed to align the stock fan! It it possible that the screws alone were to do that? Thinking that maybe it was the wrong pump, I looked at others from identically equipped Packards and they are the same with the flange and pilot long enough to only go through the two pulleys. Any thoughts on this?

Any clues of how to get the lower hose reconnected?

I haven’t had a chance to revisit the odd electrical issue because it isn’t a priority as I have been trying to stop the coolant leak at the thermostat housing. There is corrosion in the aluminum head which was fixed once years ago but it’s back now! I tried to use multiple gaskets in addition to the form-a-gasket sealer which I thought would fill the irregularities but does not.

What I tried today was to put some sealer into the deepest pits, leveled it, then let it sit. Then I applied a coat to the bottom of the gasket, which this time is the heavy cork type, and applied it, putting the housing on without tightening,

While waiting for some who actually knows to answer, check around the door jambs as the screw heads look like the types found there.

Same here in California. As a VIN verifier, I would use the engine number (or tamper proof number) as a last resort.

Napa should have them and they were even able to supply one for my 1951 Henney-Packard! (It uses three but I had two in stock already,) Best to take it in for a matchup.
