Bought a new fan clutch, Made In China (Real vote of confidence THERE!) and some epoxy.
Could NOT find anything that would either fit the broken piece I had, or would fit the radiator. All the fittings they had were plastic, not Teflon.
For laughs, I went to the Abuchon Hardware store, looking for copper tubing, whatever. They had a fitting like what Ray suggested, for joining two pieces of tubing together.
It fit into the broken piece quite snugly!!!
I installed the fan clutch, and the fan, and then went to the task of repairing the raditor.
The broken end was wider than the end on the radiator, so I ground down the brass fitting with enery cloth, and very gently hogged out the openeing in the radiator with a drill bit. I was able to install the brass fitting up to the second 'knuckle', so I tuged it out and coated it with epoxy. Then I put a bead of epoxy around the union, and placed the loose hose on it. Too big! But, I still had the broken piece, so I put some more epoxy on the free end of the brass fitting, and the broken piece snapped on like it was made to do just that!
The hose installed back on just like it should. Everything looks good. I have some snapshots; I have to get them out of my phone. Not the *best* job I have ever done, but it looks like it will work!
The only thing was the epoxy said it was only good to 200 degrees F. Hopefully, it will hold...
Geeze for once I lucked out!!!
