Radiator re-weld

So the fill cap on the Discovery’s really need a special wrench, which is ok because normally you don’t have to empty it that often. My truck never had a flush, since I bought it, and it had questionable service from some of the owners, it was about time. I used an adjustable wrench, the plastic radiator cap basically disintegrates. This was not a great idea.

Being that it’s 22 years old, it splits in the most annoying method possible, laterally. So I message it out with a screwdriver, a hammer and a chisel, straight into the radiator, not too bad, in that I can drain the radiator to get that out.

Atlantic British sells a brass replacement part (ERR4686B, $3.95) so after filling back in the brass with some filler rod, filing the neck down flat, and retapping the hole using a 21 x1.75mm tap and a 12 point 9/16 socket, the replacement fits in.

I did 3d print the special socket to screw the cap in this time, and installed the plug. The print is available on thingverse

In this whole process, the bottom hose broke, which is an odd design, which looks like the picture below, which was liberated from some auto parts seller who intern liberated it from the manufacturer.

I should redo it out of regular hose, but it’s only 22 bucks. It would be nice to add some features, like a coolant heater, and a drain plug. It could be made of a 45 degree copper fitting with two adapters soldered on, which would allow for a drain plug. Things left:

  • GPS, cameras, etc.
  • Other random stuff as it decides 22 years is enough.
