Last night the wife and I went out to dinner. It was a pleasant, cool evening. When I parked the car, I noticed the electric water pump was not running.

When we got home from dinner and I parked the car, the water pump did run.

I've noticed the engine runs considerably cooler since I removed the A/C condenser. Prior to pulling the A/C, the electric water pump ALWAYS ran after I shut off the engine.

My question is, is the electric water pump supposed to always run, or does it only run when some heat threshold is reached?
