T4 Cylinder Head Water Flange (AHY,ACV,AET,AEU,AJT,AHY,AJA,APL,AVT,AUF,AYC,AYY Engines)

Keep your VW T4 running cool and leak-free with this replacement plastic water junction, designed to locate securely on the side of the cylinder head.

This coolant flange directs coolant flow between the cylinder head and cooling hoses, and over time the original plastic can become brittle, crack, or leak—leading to loss of coolant and overheating. This good quality replacement includes the base seal for a proper watertight fit and long-term reliability.

Compatible with a wide range of 2.5 TDI and 2.5 petrol engines, this flange is essential maintenance for any Transporter T4 reaching higher mileage or showing signs of coolant seepage around the cylinder head area.
