T4 Metal Water Pipe - Metal Pipe From Water Pump To Oil Cooler (Manual Gearbox Only)

This metal water pipe is a direct-fit replacement for a range of VW Transporter T4 models fitted with manual transmissions. Running between the water pump and the oil cooler, this pipe forms part of the essential coolant circulation system. A failing pipe can cause coolant leaks, overheating, loss of system pressure, and contamination of surrounding components—making timely replacement crucial for engine reliability.

Constructed from durable steel and designed to match the original diameter, bends, and mounting points, this replacement pipe restores proper coolant flow and fits cleanly within the T4’s compact engine bay layout. It is suitable for a range of petrol and diesel engines used throughout the later-production T4 years.
