Setup, Compatibility & Care
Before starting the installation, ensure the vehicle engine is completely cool. The primary compatibility requirement is matching the part to OE number 1 412 398. When installing, verify that the viscous clutch mount is clean of debris or old grease. Tighten mounting bolts to the vehicle manufacturer’s specific torque settings to prevent vibration. For care, visually inspect the blade wings for cracks or signs of fatigue during every routine oil change. Keep the area around the clutch free from heavy buildup of road grime or oil, which can impede the thermal sensor on the viscous coupling and lead to premature fan engagement or failure.
