Anyone using an electric water pump?

Slowing down the air flow through the radiator quickly saturates the contacting layer of air to no effect on the surrounding layer, which is why no one recommends it.

Yes, I understand. The post you quoted was actually meant to be sarcasm. What most fail to understand is that the same applies to both air and water flow with regard to flow rate.

Late to the party here...but...I have found a huge benefit in my elec water pump (Meziere) is that when I shut down I can turn the key on and have water pump & fan run for a couple of minutes with the engine turned off in order to mitigate heat soak. This is a huge up side if you do any restaurant hopping and only shut down for an hour or two at a time. I've had heat soak issues in the past and this has cured that problem 100%.
