Jim,

It's hard to see in your picture, but there should be little two "nubs" on inside of the thermo housing where are used to keep the retainer pressed against the thermostate.

This is a picture of my thermostat housing. This is a reproduction housing made of solid brass, but here you can see the "nubs" I am talking about. The original should have something similar, but just pressed in indends in the original stamped metal housing. Hopefully they didnt rust off, or get pressed back out.

My original housing was paper thin from rust, so I had to replace it. Not sure if I still have the original laying around or not. But I will check.

BigKev: My themrostat housing:

(a) has NO nubs

(b) is entirely different in shape than yours, AND the base on mine is formed stamped metal,no cast like on yours.

How can this be????

My Packard is a 1952 200 Deluxe with 288 cubic inch 135 hp engine.

Jim,

My housing is a reproduction one that is made of solid brass so it wont rust like the stamped sheet metal ones. It is made by one of the local PI chapters. But that aside, the nubs are the same. I went out to the garage and found my original one. You can still see the nubs on it. They are inline with the housing mounting ears. Any 288/327 from 1951-1954 will use this same housing. My 327 actually has a 288 head on it for a bump in compression.

My nubs must have worn or rusted off over the years, I guess.

1. Where do I get a new reproduction or NOS thermostat housing?

2. I assume I will again need a new gasket, even if I do the replacement of the housing within a few days of installing today's new gasket?

3. I suppose that now there is a good possiblity that the darn thermostat will again fall out of position in the meantime. Any chance that the retainer ring could actually fall into the engine, or is that impossible? Should I disassemble again, remove the thermostat and retainer entirely, and run no thermostat until the new housing and gasket can be obtained? Its 95 to 100 degrees here right now virtually every day, so the thermostst should be wide open anyway vritually all the time except on startups.

I would remove the retainer and thermo and put it aside until you can get a replacement housing. You dont want the retainer getting lost down in the head somewhere. Kanter, Max Merrit, should have originals. Last time I looked in Kanters catalog, they also had bronze (I was mistaken about it being brass) reproduction housings. I think there's is $120, expensive but they will probably last longer than either of us. I think I paid $89 for mine from the local PI chapter. I belive it was the San Diego region, but it may have been the Southern Calif region. I cant remember which one it was.

Now, if the rest of the housing is in good shape, and the metal is not too thin, then perhaps you can wire brush the metal inside where the nubs are supposed to be until it's shinney and clean, and lay a couple small beads with a MIG welder to recreate the nubs. Just enough on each side to give the retainer somewhere to rest. You can see about what they need to look like from first set of pics. You got nothing to loose. If it doesnt work out, then you will need another housing anyway.

As far as the gasket goes, as long as you didnt glue it on, you should be able to reuse it. Remove the housing bolts and tap the housing sideways to break it loose, rather than pulling up on it. I just give those kind of paper gasket a super thin (paper thin) coating of gasket sealer. So you should be able to reuse it as long as you didnt use a gasket glue, or and didnt go crazy with the silicon or sealer.

Howard, thanks for that. Cheaper than I remember, and that is exactly where I bought it from. At the Packard swapmeet all those chapter booths start to look alike!

Thank you both, BUT that $60 price was last refreshed, accoridng to the little note on website maintenance, in 2002! I suspect it costs more right now.

I have sent an email to the folks there, as there are no provisions for telephone contact at all. I've asked them how I can buy both the cast housing and the matching retainer (advertised on the same page, as I strongly suspect that retainer is DIFFERENT than the normal Packard one, as the part number is unique.
