Restore the operation of your vehicle's air-conditioning compressor without replacing the complete compressor with this replacement A/C compressor pulley and clutch assembly.

Designed for compatible Volkswagen Group air-conditioning compressors associated with OE reference 5Q0816803H, this assembly features a 6-groove (6PK) pulley with an approximately 110 mm belt-running diameter.

This component is ideal where the compressor itself remains serviceable but the pulley, bearing, drive hub or clutch assembly has become worn, noisy or damaged.

The 5Q0816803H compressor family is used across a wide range of Volkswagen, Audi, Skoda and SEAT vehicles. Because different compressor manufacturers and revisions may be fitted to the same vehicle model, the existing compressor and pulley specifications must always be checked before ordering.

Key Features

6PK Pulley Design

Features a 6-groove pulley designed to correctly engage with compatible 6-rib auxiliary/serpentine drive belts.

Approx. 110 mm Pulley Diameter

Designed around an approximately 110 mm belt-running diameter for the applicable compressor configuration.

Cost-Effective Compressor Repair

Allows the damaged or worn pulley assembly to be replaced without automatically replacing the complete A/C compressor where the compressor itself remains serviceable.

Direct Replacement Design

Manufactured as a replacement for the corresponding factory-style pulley assembly, providing the correct configuration when matched to the appropriate compressor.

Suitable for Professional A/C Repairs

Ideal for automotive air-conditioning specialists, workshops and technicians repairing compressor drive-related faults.

When Might the Pulley Need Replacing?

A worn or damaged A/C compressor pulley assembly may cause symptoms such as:

• Grinding or rumbling noises from the compressor area
• Pulley bearing noise
• Excessive pulley movement or play
• Damaged pulley grooves
• Uneven auxiliary belt wear
• Belt vibration
• Compressor drive problems
• Seized or damaged pulley bearing
• Visible damage to the pulley or drive hub

Correct diagnosis should always be carried out before replacing individual compressor components.

IMPORTANT FITMENT INFORMATION

Please confirm compatibility before purchasing.

Vehicles within the same make, model and year may have been supplied with different A/C compressor manufacturers or compressor revisions.

The OE number 5Q0816803H refers to the complete compressor, and the same general vehicle application does not automatically guarantee that every compressor uses the identical replacement pulley.

Before ordering, we strongly recommend comparing:

• Existing compressor part number
• Compressor manufacturer/type
• 6-groove / 6PK pulley configuration
• Approximately 110 mm pulley diameter
• Centre shaft/hub design
• Pulley depth and offset
• Overall physical design

For the most accurate identification, provide the VIN/chassis number and a clear photograph of the compressor identification label and existing pulley.

Installation Information

Professional installation is strongly recommended.

A/C compressor pulley replacement may require specialised tools and correct removal/installation procedures. Incorrect installation can damage the compressor shaft, pulley bearing, drive hub or auxiliary belt system.

The cause of the original pulley failure should also be diagnosed before installation of the replacement component.

Please Note

• Pulley/clutch assembly only
• Complete A/C compressor is NOT included
• Vehicle compatibility is supplied as a guide
• Match the existing compressor and pulley before ordering
• Different compressor manufacturers/revisions may be fitted to the same vehicle
• Professional installation is recommended
• Always verify fitment using the existing component specifications and OE reference number
