That is pretty cool.
Not really a fan of aftermarket electronic wizardry controlling my cooling that much, but the part about cycling after shut down is a great idea.
Wonder how much it costs?

i have to say that fitting it into a C3 may be tight but the concept is interesting. with some type of controller a different pump could be used. these new brushless fans would minimize the power loss of the alternator.

Correct me if I've misunderstood something. While the engine is warming up (with the original thermostat removed, correct?) the controller will modulate the pump (on for a while, off for a while). Seems to me that there will be warm (not yet hot) water being pumped out of the engine and cold radiator water being pumped into the engine during the pump on times. Given that most engine wear is during the warm-up period, this ripple effect of letting the coolant warm up, and then pumping cold radiator water into the engine seems silly. In effect (again, if I'm understanding things correctly) the engine warm up time is for the whole coolant volume (engine and radiator), not just the engine coolant volume.
While the engine is hot (or cooling down) I'm comfortable with the pump being controlled by the electronics.

if the pump didn't "modulate" the coolant in the engine would heat up and the radiator would stay cool. i think its design is to get the entire system up to temp as quickly an evenly as possible. not a perfect design , but it is pretty good.

Seems like an interesting starting point, have wondered why something similar was not done as a factory system to control heat soak in hot climates. Why not cycle the fluid and not just pull air over the radiator.
However, for a V8 Chevy motor couldn't the same thing be done with a normal electric H2O pump? I understand you would lose the pulley, bracket mounts, etc, but supporting the pump would be much better..
Also, controller wiring looks cheap for an under hood part.

This system needs a couple water control solenoids to prevent water flow into the radiator until the engine warms up, while also allowing a recirculation of the coolant inside the engine water jacket.

it may be a perceived problem , but may not be in actual use. we are dealing with an unknown warm up time. being no initial flow it is possible warm up times are identical , faster , or slower.

These guys have a nice "first cut" setup going. It just needs to be refined to do the whole job properly.

Interesting idea. The software in the controller can be made to completely stop water flow or really speed it up.
In our cars the biggest hurtle seems to be mounting the pump in the lower hose, not much space down there.
