1162000122 Viscous Fan Clutch Assembly for MERCEDES-BENZ S-Class W116

1162000122 Viscous Fan Clutch Assembly for MERCEDES-BENZ S-Class W116

For MERCEDES-BENZ S-Class W116 cooling-system service, this viscous coupling is catalogued under 1162000122 . Item BZ01012-024 separates the pictured hub from alternatives with different threads, offsets or engagement characteristics.

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.

Product Technical Specifications

Cooling-Airflow Control

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.

Fitment Evidence to Compare

Confirm 1162000122 against the original MERCEDES-BENZ S-Class W116 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 MERCEDES-BENZ S-Class W116 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.

Pre-Shipment Review

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 1162000122 and BZ01012-024 as the start of the MERCEDES-BENZ S-Class W116 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

For wholesale pricing, provide 1162000122, SKU BZ01012-024, quantity, destination and packaging preference. Separate every OE line in mixed cooling-system enquiries.

Frequently Asked Questions

How can I verify 1162000122 for MERCEDES-BENZ S-Class W116?

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 1162000122 as a sample?

Sample enquiries are welcome. Send SKU BZ01012-024, destination and the comparison points that must be confirmed.

What is needed for wholesale pricing?

Provide quantity, destination, packing preference and any labeling or inspection requirement together with 1162000122.
