No water pump issues at all. Changed water pump at ~100k as preventative maintenance - things wear out, and it's FAR cheaper to change it when I have the time to do it myself without taking time off of work. And you're right - replacing the pump was pretty easy (and getting the air out of the coolant once that was replaced wasn't bad at all).

It's just that the geek in me likes the idea of putting an all electric pump on the '07 Prius (with the same engine as the new Prius with an electric pump.)

The Scotsman in me recoils at spending $535 to do so though!

A true Scot would recoil at spending $1, but I'm with you on the geek part.

I have worked out a temperature PWM speed control circuit with time delay shut off to prevent temperature spikes on engine shut down, and quicker warm ups. Just need a pump, so I may try an in line 12v as an experiment.

I think the thermostat should stay in so that the cabin heater would get all the hot water circulation as long as the temperature of the water was not to high to require radiator cooling.
