Hi folks

I have had a leak that has been difficult to trace, not head gasket (as no yoghurt in the engine) not radiator. I suspected tje expansion tank was split so replaced this but STILL leaking. So one last try to spot the leak with fluorescent dye in the water system. This revealed a small suspect area under ultra violet light, in the hose going into the expansion tank at the bottom.

I have been unable to locate the correct part however to order one. Can anyone help please

The model is a 2003 V70 D5 SE AUTO 2.3.

Thank you
