Where can I get one of these for a Z18XE engine? It is a coolant connector that sits just below the intake manifold and connects to a Y-tube that leads coolant from the water pump. The part often corrodes and leads to dripping on the starter motor, wrecking the starter. The opel part number is 1338328. Of course, I am in Australia and nobody seems to bother keeping the Barina (Corsa C) going, but if I can get one the old girl will live again. Thanks everyone.
