115278316197831619 Viscous Fan Clutch Assembly for BMW 5 Series E34
The product shown belongs to the 115278316197831619 thermal fan clutch family for BMW 5 Series E34. Internal item BM01012-002 should accompany every technical or commercial enquiry.
A viscous fan clutch transfers engine rotation to the cooling fan through temperature-responsive silicone fluid. It can increase fan drive as under-hood temperature rises and reduce drag when full airflow is unnecessary.

Role in the Engine Cooling System
The coupling regulates fan speed according to thermal demand rather than locking the fan permanently to engine speed. Correct engagement supports radiator airflow while limiting avoidable noise and power consumption.
Inspect for cracked blades, loose fasteners, shaft play and contact marks before replacing the hub. A damaged fan can overload a new clutch and create a safety risk.
Application Verification Guide
Confirm 115278316197831619 against the original BMW 5 Series E34 clutch, then compare the input thread or flange, fan bolt pattern, hub depth, pilot diameter and rotation direction.
- Confirm the OE number and usable cross-references.
- Match vehicle model, engine, chassis and production period.
- Check drive-side thread or flange and rotation direction.
- Measure hub height, pilot diameter and fan bolt circle.
- Verify blade alignment and clearance inside the shroud.
Classic Vehicle Fitment Notes
Older BMW 5 Series E34 vehicles may have replacement water pumps, converted fans or non-original hardware. Compare the installed thread, flange, bolt pattern and hub offset directly instead of assuming the current cooling-fan drive still matches the factory configuration.
Installation and Cooling-System Checks
Installation should be completed by a qualified technician. Follow the specified thread direction and torque procedure, inspect the fan and water-pump bearing, replace damaged hardware, and confirm that the blade rotates freely without contacting the radiator or shroud. Test the vehicle under the appropriate warm operating conditions after assembly.
Wholesale Inspection Scope
Available checks can cover bearing movement, visible sealing condition, mounting geometry, thread protection, labeling and export-carton integrity.
Ordering Specification Notes
To reduce selection risk, treat 115278316197831619 and BM01012-002 as the start of the BMW 5 Series E34 specification. Add thread or flange details, pilot diameter, bolt pattern, hub offset and shroud clearance. The resulting checklist supports quotation, approval, receiving and installation review.
Wholesale and Procurement Information

Frequently Asked Questions
How can I verify 115278316197831619 for BMW 5 Series E34?
Compare the OE label, engine application, mounting thread or flange, fan pattern, hub depth and original-unit photographs.
What does a viscous fan clutch do?
It varies torque to the cooling fan according to thermal demand, helping provide airflow without permanently locking the fan to engine speed.
Can an incorrect clutch cause fan contact?
Yes. Wrong offset, mounting or bolt pattern can move the fan outside its intended clearance, so dimensions must be checked before installation.
Can I order 115278316197831619 as a sample?
Sample enquiries are welcome. Send SKU BM01012-002, destination and the comparison points that must be confirmed.
What is needed for wholesale pricing?
