80LS1T Posted July 11, 2005 Share Posted July 11, 2005 The fitting on my LT1 thermostat housing is 1 1/4" and the fitting on my Griffin radiator is about 1 3/4"(I think its actually a little smaller but 1 3/4" will work). So I need a reducer to put in between the two different size hoses plus I need to be able to install a small outlet for the vent hose coming off the back of the heads! So I have to be able to either weld that piece in, braze it in, or drill a hole and tap it for a fitting. So does anybody know where I can get something like this? I am going to look in the plumbing section at Menards tomorrow to see what I can come up with but I am a little doubtful that I will find what I need.

Here comes trouble Posted July 11, 2005 Share Posted July 11, 2005 I had this package of rubber bushings to reduce radiator hose size of which I cannot find now. This would make a clean unobservable fit...Jegs has some filler and drain adapters from 1 1/4 to 1 1/2.. yout best bet maybe an exhaust pipe reducer that comes in about every size and cheap asw dirt if you cannot find the rubber reducer bushings..I wish I could find the package of bushings so I had a manufacturers name.

80LS1T Posted July 11, 2005 Author Share Posted July 11, 2005 Tim you are the man! That is exactly what I need and its pretty cheap, only $14! I tried to find it on Summits site but I guess I didnt punch in the right search words. Guy Quote Link to comment Share on other sites More sharing options...
BQR280Z Posted July 11, 2005 Share Posted July 11, 2005 Guy, If that does not do it for you, let me know. I have a lathe and mill so we can make up what ever you need. Bill Quote Link to comment Share on other sites More sharing options...
Guest Phil1934 Posted July 11, 2005 Share Posted July 11, 2005 Back of radiator catalogs have adapter sleeves for the smaller outlet of the two and then you run the larger size hose. Remember when auto parts had catalogs and would sell you a distributor cap without asking PB and PS or not? A/C or not? 2 dr or 4 dr?

ZROSSA Posted July 11, 2005 Share Posted July 11, 2005 I had to do a whole bunch of these for my suki 4x4. I just used some copper tube that i cut a pie shaped bit out of and then brazed then back together. Ugly but works fine. Douglas Quote Link to comment Share on other sites More sharing options...
