Abstract
A water pump disconnect clutch including: a first race having first and second portions with first and second diameters, respectively; a second race having at least one ramp; at least one rolling element disposed radially between the first and second races; and an engagement means for axially displacing the at least one rolling element. In response to an increase in temperature for the pump above a specified level, the engagement means is for axially displacing the at least one rolling element from a first position, in which the first and second races are rotationally independent, to a second position to rotationally lock the first and second races. In response to a decrease in temperature for the pump below the specified level, the engagement means is for axially displacing the at least one rolling element from the second position to the first position.
