I initially installed this part. Made some spiffy brackets, baked on some translucent powder coating. It looked good. But, the nose wouldn’t fit around it, and I needed something else.
I have a couple of plastic overflow bottles with connectors at each end. One of them even had a sight tube on the side. But they were so big around that it really didn’t fit well anywhere. I cruised through a number of catalogs, and couldn’t really find anything I liked. Canton makes some pretty cool aluminum tanks that would look pretty nice. But they’re kind of expensive.
I decided to build something smaller and cheaper. Turned out to be a lot lighter, too. The coolant overflow is nothing fancy. Just a container that can handle some heat. Even a beer can and some duct tape would work.
I made the container out of 2″ PVC plastic. Glued one cap on the bottom, and pressed the other cap on the top. I drilled a hole in the cap and another in the bottom, and inserted a tubing connector I had lying around to the bottom hole. But you could just as easily put the overflow tube through a hole in the cap, and run it down to the bottom. Lots of options, there. This just turned out to be easiest to do with what I already had.
I used some left over sheet metal ducting to make a couple of brackets; and riveted them to the frame.
Done deal. Cheap, easy, effective, and very light weight.
