Thread: Name that Hose

    Name that Hose

    Can someone help me understand the purpose of this hose on my 2008 GTI SE 155? It runs from under the engine to the rear of ski on the port side.

    Parts Finder identifies it as Hose 19mm part no. 276000158.

    Its part of the cooling system for the exhaust manifold. Its attached to the exhaust manifold.Water circulates through it, keeps your exhaust manifold from melting.

    Yup itís the main water inlet for exhaust cooling.

    The one you pinch off for towing a broken down ski.

    Same here. The Ops. Manual shows this little crossover hose on my GTI to pinch when towing.




    The hose in question connects to the exhaust manifold and terminates at the jet pump. Is this an inlet or outlet for cooling? And, this is an open loop system for cooling the exhaust?
