Role in the Engine Cooling System

Cooling performance depends on both airflow and mechanical integrity. The clutch bearing, input connection, fan bolt pattern and thermal valve must suit the original system.

Cooling complaints should not be assigned to the clutch alone. Restricted radiator fins, a damaged shroud, thermostat faults, belt problems and low coolant can produce similar symptoms.

Application Verification Guide

For MERCEDES-BENZ S-Class, compare 1162001122, engine option, water-pump connection and shroud clearance. The fan must remain centered with adequate space throughout rotation.

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.

Wholesale Inspection Scope

Sampling inspection helps confirm visible configuration and dimensional consistency before a batch is released for dispatch.

Frequently Asked Questions

Is 1162001122 suitable for every MERCEDES-BENZ S-Class version?

Not automatically. Engine, production period and water-pump or fan configuration can change the required clutch.

Which measurements are most important?

Check total height, drive-side connection, pilot diameter, fan bolt circle, fan-side offset and rotation direction.

Should the fan blade be inspected too?

Yes. Cracks, deformation, loose holes or imbalance can overload the new clutch and create a safety hazard.

Are pre-shipment photos available for BZ01012-025?

They can be discussed for sample or bulk orders, including mounting faces, profile, labels and packing.

Can private-label cartons be supplied?

Neutral or customer-specific packaging can be evaluated according to quantity, artwork and schedule.
