On a supercharged 6.2L, this pump is what keeps intake charge temperatures under control. It circulates coolant through the intercooler in the blower and out to the front heat exchanger, and when it slows down or quits, the car pulls timing and power falls off long before anything overheats in the traditional sense. Mopar controls it over the LIN bus from the powertrain module, with off, on, and run-after-shutdown modes.
