E39 cooling system / part numbers

[SuperHangOn]

I'm getting parts ready to refurb the full cooling system on my V8/M62 E39 (1997). Apparently there is a hose which runs from the engine to the matrix which is prone to bursting - anyone know which one this is? I have tried looking on realoem but can't pinpoint the one.

Thanks

Well I managed to dig out this diagram

At what point does this job get a bit silly/OTT? Is changing these hoses paranoia?

Have already ordered a radiator, ex.tank, stat, water pump, viscous fan and top/bottom rad hoses (all Behr and meyle from motormec).
