Refill your liquid source for the pump, and voila. Check (before replacing plastic cover and wheel) by starting car, letting it run for a minute or so, and then turning off. Go over to the right front wheel. You should hear the pump running for 5-20 seconds after turning the car off. Check for leaks.

This is part of the how-to from a C32 guy installing an IC pump. My question pertains to the part where he says to listen to the pump to see if it is running. I never hear my pump running when I shut off the engine. I secure it, then run over to the pump location, but hear nothing. I'm wondering about this, because I'm questioning whether or not some slight accleration issues is due to a faulty IC pump or one that is about to go out completely. Anyone ever hear their pump running at shut off. NOTE: this is not the hair dryer noise you hear at start up. You have to put your ear next to the pump to hear it.
