Technician A says the viscous clutch is filled with silicone fluid. Technician B says the viscous clutch solenoid is controlled by inputs from the wheel speed sensors. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because a viscous clutch indeed uses silicone fluid to transfer torque based on the difference in rotational speed between two shafts. Technician B is incorrect because a viscous clutch does not use a solenoid for its operation; it operates based on the shear strength of the silicone fluid and does not require electronic control from wheel speed sensors.
