You can actually feel the IC Pump if you turn your front wheels all the way to one direction and open the little "door" on the inside of the passengers front wheel well. You can peek inside with a flashlight and see the IC Pump. You can touch it and see if you feel the pump running. It will have a slight vibration from water passing through it.

The issue sounds like typical heat soak. The heat slows them down so much that I refuse to go to the track until the temps go back down!!

Good Luck~
