A straight, reinforced rubber bypass hose from the water pump to cylinder head, as used in original applications. May have to be trimmed to shorten if you have a replacement 12A2075 bypass fitting in the head. Ref: AEG0484K, AEG484, AEG484K.
For installations where the head or water pump have been removed. We recommend replacing this when the water pump or head gasket are changed, it is a cheap insurance. This is much stronger then the soft rubber collapsible hose designed for fitting while the head is still on the block.
See C-GZA2083 for silicone version.
