077121302D Viscous Fan Clutch Assembly for AUDI A6
The 077121302D fan clutch is presented as an aftermarket replacement reference for AUDI A6. Quoting AD01012-006 helps connect the product images, application notes and packing requirements.
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.

Role in the Engine Cooling System
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.
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
Fitment for AUDI A6 should combine 077121302D 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.
Wholesale Inspection Scope
Buyers may request photographs showing the front, rear, side profile, mounting details and completed export packaging.
Ordering Specification Notes
Procurement documentation for AUDI A6 can combine 077121302D, AD01012-006, cross-references, critical dimensions and inspection criteria. This makes sample comparison more practical and supports repeat-order consistency even when several fan-clutch versions share a similar housing.
Wholesale and Procurement Information
Importers can quote 077121302D and AD01012-006 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 AUDI A6?
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 077121302D?
Trial and sample requests can be reviewed against SKU AD01012-006, 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.
