T4,G3,G4 Water Pump - VR6 Engines (AES Engines)

This high-quality replacement water pump is designed for all Volkswagen Transporter T4 models fitted with the 2.8 VR6 AES engine, ensuring reliable cooling system performance on one of VW’s most powerful T4 engine options. Built to OEM standards, it restores correct coolant circulation throughout the engine, radiator and heater matrix, preventing overheating and maintaining stable operating temperatures under load.

The VR6 engine relies on a robust, high-volume pump to manage the increased thermal output of its narrow-angle six-cylinder configuration. This replacement unit features a precision-machined impeller and durable bearing assembly, ensuring efficient coolant flow and long service life. Whether your original pump is leaking, noisy, or suffering from bearing play, replacing it prevents coolant loss, overheating and potential head-gasket damage.

While primarily specified for the T4 AES 2.8 VR6, this water pump also fits several other VR6 applications, including AAA 2.8 VR6, ABV 2.9 VR6, and AES 2.8 VR6 engines used across vehicles such as the Corrado and Golf Mk3. Always confirm engine code compatibility before fitting.

What the Part Does

The water pump drives coolant circulation through the engine block, cylinder head, radiator and heater system. On VR6 engines, correct coolant flow is essential due to the compact block design and high thermal density. A failing pump can lead to overheating, poor heater performance, coolant loss, or engine damage — this replacement restores proper flow and stable temperatures.

Installation Notes & Additional Parts That May Be Needed

• Direct replacement for AES 2.8 VR6 T4 Transporter engines.

• Also suitable for VR6 engines coded AAA, ABV, and AES across other VW platforms.

• Recommended extra parts during installation:

  • water pump gasket/seal

  • fresh coolant (VW G12/G13 depending on system spec)

  • auxiliary belt (if showing wear)

  • thermostat and housing (commonly replaced at the same time)

• Check plastic coolant pipes, housings and flanges — VR6s are known for age-related cracking.

• No special tools required, though access varies by vehicle platform.

A dependable replacement that restores essential cooling performance on any VR6-powered vehicle.
