Yes yes yes very good. You could post that picture any time, jEFF.

Well the truck's engine didn't cook itself. Nor did it overheat on the trip home. But this is very easily explained, maybe I’ll use pictures to demonstrate. Yes, I think I will.....


Ok this picture is from when I had it apart before, with the leaking and such when I first got it.



A little theory of operation first:
As the picture illustrates (looking at the pump from the engine side), the shaft and the impeller come through, driven by the fan belt, and spin. Water comes in from the bottom of the radiator, after being cooled, around the shaft, gets pumped out through those channels and back in to the engine to get heated. All this happens AFTER the water in the engine reaches a certain temperature, and the thermostat opens to allow water in to the radiator to be heated. Before that, the pump merely circulates the water through the engine and cabin heater. Prior to full-temp, water enters the pump through the bypass (top of picture) which draws heated water from behind the thermostat, as well as from the heater return hose, and pushes it back in, to keep water moving across the metal and evenly reach operating temperature. The feed for the cabin heater comes directly from the engine, and is not visible here.

What most likely happened (haven’t opened it yet, but I can make a very well educated guess) is the shaft and the impeller, being connected not with a welded joint, but are only press-fitted together. Well it is not unknown for them to become no longer connected once they reach high speed and temp, so this is what most likely happened, during my trip down the mountain highway. So by the time I hit 224th, it was not drawing any water from the radiator, causing it to overheat. But the slow, easy trip home, down 224th, 46th and other such back roads, was not stressful enough to cause the impeller to stop...?impelling?-if that’s the word.

But I didn’t pull it apart tonight (slightly warm after the drive). The plan for the trip home was, drive it until it gets warm enough to worry me, pull over and tow it the rest of the trip with the red & white Ford (the old one I used to drive) but it never got above normal temp.


Anyway-

We got a KVM switch today (Keyboard Video Mouse)

It allows you to connect up to 32 computers to 4 workstations-each of the workstations being a monitor, keyboard and mouse.. Quite the thing, it has a bunch of video and mouse inputs, and comes with a variety of really long (up to 35 feet) video, mouse and keyboard cables. You just pick which computer you want to work on, and BOOM you have it’s display. And it only cost ${censored}.

I’ll take some pictures to illustrate.


(by the way-geocities sucks big fat hairy scrotum. The file "pumpgraphic.jpg" was not accessable, was not being shared out by their server, so I spent quite some time tryimg in vain to get it to work.)
