55056840AC Viscous Fan Clutch Assembly for FORD
Primary reference 55056840AC is the starting point for matching this FORD fan clutch assembly. Buyers should include FD01012-021 in dimensional, sample and volume enquiries.
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.

Thermal Fan-Drive Function
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.
Compatibility Review Before Ordering
Use 55056840AC together with FORD 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.
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.
Inspection and Export Preparation
Pre-shipment review may document both mounting faces, fan-side pattern, hub depth, surface condition and protective packing.

Frequently Asked Questions
What is the safest way to confirm FORD compatibility?
Combine OE 55056840AC, 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 FD01012-021 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.
