Four Seasons Engine Cooling Fan Clutch P/N:36782
Restore proper engine-cooling airflow with the Four Seasons Engine Cooling Fan Clutch 46001, a thermal, standard-rotation, standard-duty unit engineered for a wide range of BMW V8 and V12 models — including the 1988-1994 750IL [V12-5.0L], 1994-1995 530I [V8-3.0L], and 1997-2003 540I [V8-4.4L]. As a thermal fan clutch, it uses a temperature-sensitive element to engage its viscous coupling and drive the cooling fan as underhood heat rises, then lets the fan freewheel when cooling demand is low so the engine isn't dragged by the fan unnecessarily.
Manufacturer part number 46001.
Fitment: 750IL 1988-1994 [V12-5.0L] & 1995-2001 [V12-5.4L]; 850I 1991-1992 [V12-5.0L]; 740I 1993-1995 [V8-4.0L] & 1997-2001 [V8-4.4L]; 740IL 1993-1995 [V8-4.0L] & 1996-2001 [V8-4.4L]; 850CI 1993-1994 [V12-5.0L] & 1995-1997 [V12-5.4L]; 530I 1994-1995 [V8-3.0L]; 540I 1994-1995 [V8-4.0L] & 1997-2003 [V8-4.4L]; 840CI 1994-1995 [V8-4.0L] & 1996-1997 [V8-4.4L]; 850CSI 1994-1995 [V12-5.6L]. See the Buyer's Guide tab for the full list.
What does this fan clutch do?
It's a thermal viscous coupling that engages the engine cooling fan as underhood temperature rises and lets the fan freewheel when cooling demand is low, controlling cooling airflow.
Is this an electronic fan clutch?
No. It is a non-electronic thermal clutch with standard rotation and a standard-duty design; engagement is controlled mechanically by temperature.
Is mounting hardware included?
No, mounting hardware is not included. It uses a HEX mount with three M6 x 1.0 bolt holes; consult the vehicle service information for the correct fasteners and whether they may be reused.
What are signs this fan clutch may need replacing?
A continuously roaring fan, a fan that freewheels with little resistance, or the engine running hot can point to a worn clutch. Diagnose the cause before replacing.
Does it meet OEM specifications?
Yes. This new unit is rated to meet or exceed OEM specifications and is performance rated for OE-level fit and appearance, with a precision-machined aluminum body.
