T4,G3 Water Pump Flange - VR6 Engines

This water pump flange is designed for Volkswagen VR6 engines and is fitted to T4 Transporters with 2800cc VR6 engines. It is also used across other VR6-powered models including the Golf Mk3 and Corrado. Supplied complete with the correct O-ring seal, this flange forms a critical sealing and connection point within the engine’s cooling system.

The flange mounts directly to the water pump and provides a secure interface for coolant flow between the pump and the surrounding pipework. A correct seal at this point is essential, as any leakage can quickly lead to coolant loss, overheating, and potential engine damage.

On VR6 engines, the original water pump flange can deteriorate over time due to heat cycling and constant exposure to coolant. This often results in leaks around the flange or hardened, flattened O-rings that no longer seal correctly. Replacing the flange and seal together ensures a reliable, leak-free repair.

This replacement water pump flange is manufactured to the correct dimensions for a direct fit on VR6 engines and is ideal for use during water pump replacement, cooling system repairs, or preventative maintenance.

Fitment notes:

• Fits VR6 engines only

• Supplied complete with O-ring seal

• Direct replacement, no modification required

Other parts that may be required or worth checking when fitting:

• Water pump

• Adjacent coolant pipes and hoses

• Hose clips and fasteners

• Coolant condition and level

Maintaining proper sealing at the water pump flange is vital for stable coolant circulation and long-term engine reliability on VR6 engines.
