T4,T5 Water Pump - VR6 (AMV,BDL,BKK,CFLA)

This replacement water pump is designed for Volkswagen VR6 petrol engines, covering 2.8 VR6 units fitted to late T4 Transporters and 3.2 VR6 engines used in T5 Transporters and selected Golf Mk4 models. Supplied complete with a sealing ring, this pump is a direct replacement for the original unit and restores correct coolant circulation and engine temperature control.

What this part does

The water pump is a critical component of the engine cooling system. It circulates coolant continuously through the engine block, cylinder head, radiator, and heater circuit, preventing overheating and maintaining stable operating temperatures. A worn or failing water pump can cause coolant leaks, overheating, bearing noise, or catastrophic engine damage if left unattended.

How it works

Driven mechanically by the V-ribbed auxiliary belt, the pump uses a 7-vane impeller to draw coolant from the radiator and push it through the engine’s cooling passages. As coolant absorbs heat from the engine, it is returned to the radiator where it cools before recirculating. The supplied sealing ring ensures a secure, leak-free fit against the engine housing.
