17417505109 Viscous Fan Clutch Assembly for BMW 735i
OE number 17417505109 identifies this engine-cooling fan clutch configuration for BMW 735i. Use supplier code BM01012-006 when requesting samples, inspection details or wholesale terms.
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.

How the Viscous Coupling Works
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.
A clutch that remains fully engaged may create excessive noise and drag, while insufficient engagement can reduce radiator airflow at low speed. Verify coolant, radiator and shroud condition as well.
Mechanical Fitment Checklist
Fitment for BMW 735i should combine 17417505109 with physical measurements. Similar-looking clutches may differ in rotation, height, thread pitch or thermal calibration.
- 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.
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.
Quality-Control Options
Buyers may request photographs showing the front, rear, side profile, mounting details and completed export packaging.
Ordering Specification Notes
For controlled sourcing of BMW 735i, place OE 17417505109, SKU BM01012-006, dimensions, rotation information and packaging instructions on one specification sheet. Include close views of the drive connection and fan mounting face so visually similar but incompatible versions can be separated early.
Wholesale and Procurement Information
Importers can quote 17417505109 and BM01012-006 when discussing samples, batch quantities, neutral cartons or customer labeling. Lead time follows the confirmed supply plan.
Frequently Asked Questions
Why is the engine code important for BMW 735i?
The same vehicle family may use different fan drives, hubs or mounting arrangements across engines and production years.
Can silicone-fluid leakage be a warning sign?
Visible leakage can indicate seal deterioration, but bearing play and engagement behavior should also be inspected.
What should be checked after fitting?
Verify secure fasteners, correct fan centering, free rotation, shroud clearance and normal hot-engine cooling behavior.
Does Yongshang Auto support trial orders of 17417505109?
Trial and sample requests can be reviewed against SKU BM01012-006, availability and the requested QC evidence.
How are repeat orders controlled?
Use the approved SKU, OE number, dimensional record and packing agreement to keep later batches consistent.
