Keep the cooling fan spinning in step with coolant temperature using the Four Seasons Engine Cooling Fan Clutch 46005, a standard-rotation, thermal, standard-duty unit. It is designed to fit the 1996-2001 Audi A4 and A4 Quattro (V6-2.8L), 1998-2001 Audi A6 (V6-2.8L), 1998-2001 (V6-2.8L) and 2000-2004 (V6-2.7L) Audi A6 Quattro, 2000-2002 Audi S4 (V6-2.7L), and 1998-2005 Volkswagen Passat (V6-2.8L).
A fan clutch is a thermally controlled coupling between the belt-driven hub and the cooling fan. As underhood temperature rises, the thermal element engages the clutch to drive the fan for more airflow; as things cool, the clutch slips to reduce fan drag and noise.
Signs the original clutch may need replacing include overheating at idle or in slow traffic, a continuous loud fan roar, or a fan that freewheels. Diagnose the cause before replacing. Manufacturer part number 46005.
