HalfdollarMayflower Posted October 7, 2009 Report Posted October 7, 2009 Anybody got a non-bypass (straight) thermostat housing? I've done a search, but haven't found anything, nor an aftermarket supplier. Mine is rusted thru in a couple places. I've got one with a slight 'bend', but I really need one that's straight. Thanks, Gary Quote
Andydodge Posted October 7, 2009 Report Posted October 7, 2009 Checkout the thermostat housing for a small block mopar V8, no bypass hole/fitting cast into it, same bolt pattern as the mopar six, I've just got one thats all shiney chrome to use on the Edgy Finned head, and theres enough room for the thermostat to fit hanging down into the head and the housing has a recess to locate the thermostat also........I paid about $20.00 Australian here in Oz but you'd get it in the US for 10 bucks or less.......try your local speed shop.......andyd Quote
Jim Saraceno Posted October 7, 2009 Report Posted October 7, 2009 I bet Vintage Power Wagons has them. Quote
Rollie��� Posted October 7, 2009 Report Posted October 7, 2009 Mine has holes too and I was going to do a fiberglass repair....will have to check to see how the small block Mopar housing fits. Quote
Rollie��� Posted October 7, 2009 Report Posted October 7, 2009 small block Mopar does fit, it's just shorter. I'm going repair mine with fiberglass since I've already bought a new hose and cut and fit it to the original housing. Quote
Andydodge Posted October 7, 2009 Report Posted October 7, 2009 Also as the V8 housing is alloy, the weight reduction will make the car go faster..............lol.........jeese I'm a wanker......lol..........still gota look for the positives....lol.....andyd Quote
PatrickG Posted October 7, 2009 Report Posted October 7, 2009 i was able to buy one NOS from Vintage Power Wagons, might want to check them out. Quote
HalfdollarMayflower Posted October 7, 2009 Author Report Posted October 7, 2009 Thanks for the suggestions guys! Here's what mine looks like...I'm afraid its too far gone. Quote
Norm's Coupe Posted October 8, 2009 Report Posted October 8, 2009 Check out the housings for Ford and Chevy. Seems I remember someone saying a Chevy housing would fit, and they are straight. Just a little shorter I believe. I'm talking about the housings for the Chevy 350 engines. Quote

stylinmike Posted October 8, 2009 Report Posted October 8, 2009 If I have a factory neck that HAS the bypass, can I replace it with one that doesnt. I guess what im saying is, is the bypass neccassary? From what I understand it prevents hot spots in the motor before the thermostat opens. How important is that? Quote
HalfdollarMayflower Posted October 8, 2009 Author Report Posted October 8, 2009 Yes, you can run without the bypass. Bypass was a standard feature on Special Deluxes until 1951 when the internal bypass ports were added to the blocks. Prior to 1951, Deluxe models did not typically use a bypass. A simple bypass on a non-bypass engine is easily engineered by drilling two or three 1/8" holes in the thermostat. This not only 'burps' the cooling system, it also allows a small amount of coolant to flow thru the system, thus eliminating 'hot spots' and reducing the liklihood of pump cavitation. I believe its an old racer's trick on SBC's. Quote
stylinmike Posted October 9, 2009 Report Posted October 9, 2009 Okay, bought a chrome water neck for a chevy V8. Bolt holes and outer shape are the exact same. However, the stock waterneck has a ridge in it for the large thermostat to sit in. This chevy one doesnt have a ridge because all the "v" style blocks from chev have the ridge built into the intake manifold rather than then water neck. So I bought a thermostat with the neck hoping I could make it fit. Unfortunately the thermostat is smaller and just falls into the head on my dodge? Any ideas? Quote
Frank Elder Posted October 10, 2009 Report Posted October 10, 2009 Get some sheet metal and put your waterneck on it, trace it out and then cut the metal to fit like the chevy gasket only make the hole in the middle a little smaller so you can use the sheet metal to hold the thermostat suspended between it and the water neck. You'll have to use sealer between the sheet metal and the housing so it won't leak. Quote
Norm's Coupe Posted October 10, 2009 Report Posted October 10, 2009 Don't know how much you are into metal fabrication, but here's one solution. Make an adapter plate that would go under the new neck. Make that opening so the thermostat fits in it without falling through. Then make the gaskets and install it that way. Quote
Young Ed Posted October 10, 2009 Report Posted October 10, 2009 What about sawing the tube portion off the rusted out neck. Put thermostat gasket old piece gasket new neck. Get bolts a little longer for the extra thickness and you should be good. Quote
Frank Elder Posted October 10, 2009 Report Posted October 10, 2009 You are so right Ed, flip it over and you have a sturdy plate and it might even be close to as tall as the oem one. Quote
Jim Saraceno Posted October 10, 2009 Report Posted October 10, 2009 Wouldn't it be easier to buy a new one from vintage power wagons for $35? Quote
Andydodge Posted October 10, 2009 Report Posted October 10, 2009 Or buy a MOPAR V8 housing that has the indent in it to hold the thermostat..........and get a chrome housing because they make the car go FASTER......andyd Quote
