Default waterpump renewal during cambelt change

The S70 T5 that I'll be picking up in a few days has 137k miles up and so is due a cambelt soon. I'm going to do it myself as it isn't that difficult a job, but... I'm undecided about whether I should replace the water pump while I'm at it. I'd usually just do that anyway, but Volvo pumps can last for 200k without any issue, so if there isn't any sign of leakage or free play I'm tempted to leave the original one in situ. Do you think that is wise?

The reason I want to put it off for now, is that when I change the waterpump I'll probably do a raft of cooling system replacements at the same time, as the system will be drained - radiator, heater matrix, coolant temp sensor, thermostat, reservoir & cap plus (probably) all the hoses.

I'm a bit reluctant to do all this straight off as I want to see what else needs attention before I spend all my money on these items - it may need the brakes or bushes doing more urgently, whereas the cooling system may be ok for another year... (I'll be doing the vacuum lines and PCV -with mod- as a matter of course).

The bottom line - do you think the original water pump is good for 150k (I doubt I'll actually do 10k this year but...) or is that exceptional?

Thanks!
