I've seen a couple of posts about trying to find radiator or coolant hoses that will work on custom applications. The attached .pdf file gives all of the dimensions,part numbers and pictures of Gates molded hoses.It can give you an idea of what hose might fit your needs and then you can go to the local parts house for a better look.I hope this will help someone. ( It's a large file so be patient while it loads)
https://www.gates.com/content/dam/g...gs/gates-molded-coolant-hose-id-guide_web.pdf Here’s another link to the Gates catalog. The previous link didn’t work too good on my ipad. Another cool thing I found was that on O’Reilly auto parts website, you can enter a Gates P/N and then get a 3D spinning view of the hose. This saved me from asking the store clerk to allow me to wander around in the back room. Not something I really want to do these days anyway.
For clarity / the images start on about page 45 of the Gates link. Read that page to see how Gates has them identified (diameter, length, etc./they get bigger as you go on). I’m sure the 3D view came from a Gates archive, but O’Reilly’s website works great once you have the number you think might work.
