Abstract
Disclosed herein is a fail-safe coolant control valve. The fail-safe coolant control valve includes a valve housing, a valve member, an actuator, and a fail-safe unit. The valve housing is provided on an outer surface thereof with at least two ports. The valve housing has therein an internal space communicating with the ports. The valve member is rotatably installed in the internal space of the valve housing and rotates via an actuator. The fail-safe unit rotates the valve member depending on a temperature of a coolant in the valve housing when a failure occurs.
