Worked on my upper radiator hose. I've been trying to find an off-the-shelf hose. I've tried a number of hoses, but have been unable to find anything that fits with my LS radiator. I ended up buying a 1-1/2" 45-degree hose piece and a 1-1/2" to 1-1/4" 45-degree piece. I put the one piece on the radiator and the other on the engine. With tape around each section, I marked the mating points. I then cut a 6" long piece of 1-1/2" diameter stainless steel tubing and put these together. I then used a Gates Power Grip, shrink clamp to hold the pieces together. Worked out pretty good.
Both hose sections were installed and the mating points were match-marked with tape and marker
I installed a 6" piece of 1-1/2" stainless steel tubing inside the hoses, keeping the match marks in line.
I used a Gates Power Grip shrink clamp to hold the two sections together. The shrink clamp part number is 32948. It fits 1-3/4" to 2" diameter.
Make sure that if you don't want to see the markings on the clamp that you clean them off before you heat shrink the clamp on. If you try to clean it afterwards, the lettering won't come off.
Final result fit perfectly!
