A vehicle electric machine may include a rotor. The rotor may cooperate with a stator including a core having an end face, and end windings extending from the end face. A cooling tunnel may encase the end windings, sealing against the end face at opposing sides of the end windings, and defining an inlet configured to receive coolant. The cooling tunnel may be arranged to contain the coolant during passage over the end windings and direct the coolant toward an outlet.
