Timin belt - water pump as well?

Hey,



Got a 10 year old 1.4 K series with 113,000 kilometers, 70,000 miles in old money.



Since antifreeze is corrosive to headgaskets, I run with coolant where I set the antifreeze/corrosion inhibitor strength using a hydrometer to only have enough antifreeze in there to give the minimum level of protection I need (excess -7 degrees C or about 15%).



Still on factory headgasket!



This strategy may reduce corrosion protection for pump though - although I have no problems thus far...



Anyway, going to do the timing belt - wondering if there is any need to do waterpump as well?



Given that it seems a leaky water pump can't contaminate belt, I presume pump unlikely to seize and snap belt?



Is it common to leave pump in for high mileages?
