Trying to find a 1.75" radiator hose elbow (both 90 and 45 degrees) to connect my sbc water pump outlet to my aftermarket radiator. I thought that these would be simple to find, but after searching i've had no such luck... The plan is to use two elbows with some straight copper pipe in between the elbows. Any suggestions?
Go to autozone and ask to comb their inventory. You may not get it the first time but you should find one that works. If the hose needs to be 13" or more you could use a flex hose.
That was my other idea... 1.5" copper pipe sweated together with some straight couplers as connectors to the water pump and radiator inlet...
Copper is used quite a bit. Napa has those elbows that you are looking for in the radiator hose book. If they can find the one page, there's radiator hose bushings and formed hoses. Napa part 1037 1-3/4 x 45* Napa part 1038 1-34 x 90*
I always build a wire model out of a coat hanger take it and a tape measure to the parts store and ask to look at the hoses. You may have to buy a couple hoses to get all the bends you need but it has always worked for me.
The Gates "Powergrip" radiator hose heat shrink works great for splicing a couple elbows together using a copper insert.
check the plumbing dept at the hardware store as 1.5" piping is flared out to 1.75" like you need. can't the local muffler shop flare some pipe?
If you go to the gates website you can download a pdf with hose numbers, dimensions and pics and it's 117 pages.....but you have to register for it. Gates 20357 Gates 21909 Gates 22896
I agree with 55dude. I have the local muffler shop bend pipe for me quite frequently for coolant system purposes >>>>.
I rarely shop for a difficult hose shape. I like using exhaust U-Bends to build a complete unit and just short strait coupeling on each end. You can use S.S. bends or steel and coat them. Black powder coat looks nice and most don't even notice what's going on. The Wizzard
Orilley's sells a radiator hose repair kit with 1.25" and 1.50" and 1.75" barbed couplings. I needed to get a 1.75" hose to do a double bend. I cut the two necessary sections from a long hose that had many bends, inserted the barbed coupling, rotated both hose ends to make the required bend angles. Hasn't leaked a drop in 4 months.
or cut a 1 3/4 piece of exhaust tube at 45 degrees and reverse, then weld together and get some industrial straight hose and assemble
I see exhaust pipe rusting inside over time. Once you take the time and get the right hose all you need it the application for next time. I would say either rubber or stainless.
This hose is great cuz it has a small bend at one end. I find if it doesn't fit one way , spin it around and it usually does the other way.
This thing is Awesome!. Just used one to make a custom set up. Cut the 45* from the 90* and put it back together. Just like doing custom exhaust work.
Sorry about resurrecting an old thread like this, but I'm looking for hoses for my '40 Chev project and not having any luck yet. I found this thread using the search function, registered at the Gates site, and downloaded some catalogs. All the pictures in those catalogs are very small, low resolutions pics that show no detail when zoomed in. Where did you find these pics and part numbers? Armed with dimensions and pics of this quality, finding something that'll work should be easy. Any help would be much appreciated. Thanks.
I just bought six stainless 1.75 90 and 45 fittings for the same thing on Ebay. They were only 6 or 7 dollars each
After cutting up $50 worth of rubber hoses and still not getting there I made mine with stainless 90 and 45 mandrel bends, took six pieces welded together but was the only way I could get there without moving the altrenator. The engine is a Dodge 270 hemi with a Chevy water pump.
