Q: What is the difference between a 'friction disc' type and a 'silicone fluid' type fan clutch?
A: This is a key technical distinction:
Silicone Fluid Type (Most Common): Uses viscous shear of silicone fluid to transmit power. Operation is smooth, progressive, and quiet. It allows for variable fan speed based on temperature. This is the modern standard for most vehicles.
Friction Disc Type (Older): Uses a thermostatic coil to press friction discs together, much like a simple clutch. Engagement is often more abrupt and noisy. This is an older design rarely used in modern vehicles.
All our products are the advanced silicone fluid type for smooth and reliable operation.

Q: The old fan clutch is really stuck on. How do I remove it without damaging the water pump?
A: This is a common challenge. Do not hammer on the blades or pry on the radiator.
1.Use the Right Tools: A fan clutch wrench set is essential. It includes a thin wrench for the large clutch nut and a larger one to hold the pulley.
2.Shock It Loose: A few sharp, firm taps with a hammer on the end of the wrench handle (once it's on the nut) can break the corrosion bond. A pneumatic impact wrench (on low setting) is very effective for this.
3.Penetrating Oil: Apply a quality penetrating oil to the threads and let it soak in for 15-30 minutes before attempting to loosen.
The goal is to shock the nut loose without applying sideways force that could bend the water pump shaft.

Q: How long does it take for a fan clutch to start working normally after a cold start in winter?
A: After a cold start in winter, a fan clutch typically begins to work normally 5 to 10 minutes after the engine starts, which is when the engine coolant temperature rises to around 80℃. This delay is intentional, as the clutch stays in a disengaged state initially to help the engine warm up quickly—cold winter temperatures slow down engine warm-up, so the clutch avoids unnecessary fan rotation that would draw away heat. If the ambient temperature is extremely low (below -15℃), the warm-up time may extend to 12 to 15 minutes. During this period, the fan only rotates slightly due to drag torque, not enough to affect warm-up. For silicone oil fan clutches, the low temperature increases oil viscosity, which also slows the valve’s response time, contributing to the delayed engagement. For electronic fan clutches, the ECU detects the low coolant temperature and keeps the coil current low, preventing early fan activation. Once the coolant reaches 80℃, the clutch gradually engages, adjusting fan speed based on temperature to maintain optimal engine operation. If the clutch engages earlier than 5 minutes (causing slow warm-up) or later than 15 minutes (risking overheating), it may indicate a faulty sensor (electronic type) or stuck valve (silicone oil type).
