Look ma! No radiator!

I’ve put the new one in, but have not run it.
After draining the old gas out of the tank and replacing with new, I discovered that what I thought was bad gas sound was actually the supercharger coupling. I replaced the coupling years ago, but it doesn’t have many miles on it, so I am a little bit perturbed that it is worn out already. That’s another $50 and a couple hours of time down the drain. I’ll tackle that job today, then I won’t have to listen to it knock while I flush the radiator. Then this car, in theory, should be mobile again.
It certainly needs a bath after sitting for so long.
In other bad news, my truck developed a dragging sound in the brakes, and I finally located it. It was a rear caliper that was failing to release, which destroyed a pad and rotor that are not even a year old yet. I had that brake apart a few months ago, and didn’t notice any unusual wear. Apparently when a caliper sticks, the pad and rotor tear up fast, and without enough warning until it is too late.
So that’s more money out the door.
I haven’t faced this problem before. It looks like the slide pins could be sticking. On this caliper, the pins stay with the bracket when the caliper comes off. I don’t know how the pins come out, but it looks like I’m getting to learn. Greasing the pins is a much easier and cheaper fix than replacing, or rebuilding the caliper; another thing I haven’t done yet. Hopefully that’s all the problem will be, but I’ll still have to get new rotors and pads.
