9042000922 Viscous Fan Clutch Assembly for MERCEDES-BENZ
Designed for comparison with the original MERCEDES-BENZ cooling-fan drive, this assembly is indexed by 9042000922. Catalogue code BZ01012-031 keeps its mounting and hub details traceable.
Thermal fan clutches are designed to engage progressively as cooling demand increases. Their response works together with the radiator, shroud, coolant circuit and belt-driven accessory system.

How the Viscous Coupling Works
The fan clutch allows controlled slip when extra airflow is not needed, then transmits more torque as temperature rises. This reduces the drawbacks of a permanently rigid fan drive.
Constant fan roar, weak airflow at idle, overheating in traffic, hub wobble or silicone-fluid leakage can indicate fan-clutch wear, although the complete cooling system should be diagnosed.
Mechanical Fitment Checklist
Send 9042000922, MERCEDES-BENZ engine details and original-part photographs when interchangeability is uncertain. Front, rear and side views are especially useful.
- 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
For repeat orders, sample records can compare hub dimensions, hole positions, surface finish and carton labeling with the approved reference.

Can I select 9042000922 from the product photo alone?
No. Similar housings can have different threads, offsets, rotation or fan patterns, so physical and catalogue checks are required.
What other faults can resemble a weak fan clutch?
Radiator blockage, low coolant, thermostat faults, belt slip, damaged shrouds and water-pump problems can create similar symptoms.
May old mounting hardware be reused?
Only if the service information permits it and every fastener is undamaged. Follow the specified direction and torque.
Can export packing be adjusted for BZ01012-031?
Carton protection, neutral labels and customer branding can be reviewed according to volume and destination.
