1162000622 Viscous Fan Clutch Assembly for MERCEDES-BENZ S-Class W126

1162000622 Viscous Fan Clutch Assembly for MERCEDES-BENZ S-Class W126

OE number 1162000622 identifies this engine-cooling fan clutch configuration for MERCEDES-BENZ S-Class W126. Use supplier code BZ01012-023 when requesting samples, inspection details or wholesale terms.

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.

How the Viscous Coupling Works

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.

A workshop comparison of cold and hot engagement can support diagnosis, but the test procedure and acceptable behavior depend on the vehicle manufacturer.

Mechanical Fitment Checklist

Use 1162000622 together with MERCEDES-BENZ S-Class W126 model, engine and production data. Measure the overall height and check fan-side and drive-side mounting details before approval.

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 W126 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.

Quality-Control Options

Pre-shipment review may document both mounting faces, fan-side pattern, hub depth, surface condition and protective packing.

Ordering Specification Notes

When requesting 1162000622 for MERCEDES-BENZ S-Class W126, attach SKU BZ01012-023, quantity and a dimensional drawing or annotated photos of the original unit. This evidence helps verify the mechanical interfaces and gives the supplier a clearer basis for packing and inspection planning.

Wholesale and Procurement Information

Quotation requests should identify 1162000622, BZ01012-023, volume and delivery country. Private-label options depend on quantity, artwork and production schedule.

Frequently Asked Questions

What is the safest way to confirm MERCEDES-BENZ S-Class W126 compatibility?

Combine OE 1162000622, engine or VIN catalogue data and direct comparison with the removed fan clutch.

Can fan imbalance damage the new clutch?

Yes. A cracked or distorted blade can create vibration and bearing load, so the fan assembly must be inspected.

Is the clutch normally rigid when cold?

Behavior varies by design and recent operation. Use the manufacturer’s diagnostic procedure rather than a single hand-spin judgment.

May I approve a sample before volume supply?

Sample review can be arranged subject to availability. Reference BZ01012-023 and define the inspection checklist.

Does the supplier accept custom labels?

Barcode, carton and customer-label options can be evaluated after quantity and artwork details are supplied.
