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).

I've just had the thermostat, housing, expansion tank, water pump and pump drive belt replaced on my recently-acquired '93 325i coupe.

I drew the line at a new viscous fan and radiator or hoses, as the car's only done 63k miles.

Figured I'd rather have the peace of mind of having the common problem areas sorted rather than be driving around worried that I was going to cook the engine when something went pop...
