thermostat housing

I have what I believe is a chrome thermostat housing (looks like this, but PO put it on so I have no idea if it's really cheap chrome or stainless steal: http://cgi.ebay.com/ebaymotors/ws/eB...#ht_2816wt_820.)

It's leaking ever so slightly. My questions are:

1) is it possible that this is a cheap POS part and the bolts are tight to the point that they make the center section not seal properly?
2) if I do need to replace this housing, is there any reason to spend $50+s&h for the one from Ricks (or other parts house), or can I get away with picking one up from a local parts store?

Re: thermostat housing

local parts store is fine...in all likelihood, you can pull the one that you have off, put a new gasket, with some gasket sealer, and you'll stop your leak...

Unless, of course, you are looking for originality.

Re: thermostat housing

Generally, O-ring housings get overtorqued, warped into a bowed shape and leak.
The one shown is chromed alum housing.

As Keith suggested, buy one from a parts house.
If you want, buy the reusable thick FelPro gasket.
Snug the bolts, you're not torquing a cylinder head.

Check the construction inside, make sure the bolt bosses have no holes and the holes are close to center about the bosses to prevent the coolant seeping out the threads. Another member here had one leaked from day one and after several attempts to stop the leakage, he bought another one and compared the two. The leaky one had half the bolt showing inside.

Re: thermostat housing

If want one to last a couple decades.. get an orginal GM one
I wen thru a few chrome crap metal gasket types lasted stuff all
I now use the O ring type..they dont corrode thru the top
As mentioned above dont over torque...I also use a little locktite orange gasketmaker on the inside side of the O ring.

Unless getting Genuine GM, treat them as a 'disposable' item every few yrs ..like tie rod ends.

Re: thermostat housing

Chrome plated pot metal (POS). Will warp with just heat! -No need to over-torque. (A few inch-pounds is plenty, anyway)

Wet & dry sand paper on a sheet of glass or something flat, kerosene and elbow-grease will flatten it nicely until it warps some more.

The O-ring is a good idea, but the Made in China quality is very typical.

As suggested, get a used GM housing and a re-useable FelPro O-ring gasket.
Much better.

Nov 68 Van Nuys. 327 floor-shift-auto, Frost Green and not much else when new.

Someone actually suggested that to me before I read this. I certainly like the idea of saving a few bucks, but I don't like the idea of it just getting warped again. Think I'll hunt for an orig GM.

Incidentally, I'm getting rid of the chrome-plated radiator hose, too. Just a little too much bling bling, for my tastes anyway .

Thanks, all, for the feedback.

Chrome for show, black for track m8
you would be very surpised how much heat a polished or chrome hoses, sumps, tappet covers, diff covers, trans sumps etc hold heat in....and how much they disperse with a coat of matt black...and how many track engines have been destoryed by oil running hot and latent heat ..

I haven't played in a long time, but that reminds me of the old saying in golf: "Drive for show, putt for dough."

I'm really not a fan of any inappropriate chrome, so the info about heat build up is very good to know. PO put a lot of it in places that I wouldn't (therm housing, rad hose, diff cover, fuel lines, alternator, A/C compressor). But, you know, it's there and paid for, whereas non-chrome will have to be bought. Maybe I need to post some classified ads and look for some trades.

Stupid question, but does swivel not deteriorate the integrity of the housing at some point? Seems like if it's on a swivel there would be more parts to wear out/warp/whatever.

Re: thermostat housing

M8 this country is so screwed up
Golf is a working mans game...it is the most participant played game in the country by a long shot....working man Im talking a part picker in a warehouse, the guy leaning on the shovel at the road side.
Boating...we have more boats..not dyngys, from 12" to bloody huge than anywhere in the world...every 2nd backyard has a boat, usually round a 18 to 22' runabout.
Hunting is a working mans sport...as is hot rodding and motorsports.

But shipping the Maro will not be cheap.
Rubbish..drive to LA about $NZ4500 landed here..thats just just over 3K US
And if over 20yrs dont have to convert to right hand drive
Full comnprehensive insurance here about $NZ625 for 50K
Annual regist if a 1st gen $NZ about 125
Petrol last time I checked, mexeco is cheapest, then the US with Aussie and NZ not far behind (taking into a/c exchange rate and taxes.)
health and education is free..but a doctor will cost u...cant rem $5 or $10 for an adult??
Now think of another excuse lol
And "Maro" here is a GM Aussie MONARO lol
And not to be aquesed of hyjacking the thread lol
