Here's the aftermath on the yellow C3. The wire on the middle lobe broke.

Then lobe took a good hit, too.

Nobody wants to think that these things don't work, so here's my optimistic speculation: perhaps the wire was lodged against some sharp rock and he had already ripped one piece so there must have been a big force.
Last Friday I changed the alternator on my car. Bolstered by my success on the thermostat and the alternator, it seemed like a good idea to tackle the water pump. It's been on my list for a while to change the water pump, because it seemed like the seal was failing on it and this can eventually lead to big trouble. I changed the water pump on my old Ford Lincoln with some help from my mom's ex way back when, no problem. Well it's a bigger job on the Honda, because it runs off the timing belt and requires the removal of one nemesis crankshaft pulley bolt.
Here's the rig that finally worked when impact wrenches and lesser improvisations were failing. A big chain wrench from Snap On is wrapped around the pulley with an old belt protecting the pulley. The chain wrench lodged against the car's frame stops the crank shaft from spinning.

Pay no heed to that rusty rotor.
I broke one 17 mm socket then bought a set of impact sockets. I couldn't break that nut free with a 24" breaker bar.
But the seven-foot pipe is mighty! There was a loud "PING" and finally that bolt was turning.

That's a look of fatigue and relief (worked midnight to 8 am last night).
I should have this rig reassembled and ready to go to the desert again in no time....
