how often should i replace the waterpump?

[ptownTSI]

should it be done every time the timing belt is changed?

I would do it every time you change the timing belt along with the v belts and dist cap and rotor, It is just easier doing it like that. I would prolly do my thermostat too. I Did all that when i replaced the HG in my turbo car as well as all the top end gaskets.

i think that /\/\/\/\ would be a waste of water pump money, unless you have a turbo or a stroker, just replace it once for every two t-belt changes

Id do it every t belt change as you might as well while your in there and whatever, its like 60 bucks or something. Better than having it fail and you have to pretty much the whole t belt job again for nothing.

Exactly.

You can only tension a timing belt once, so if you have to go back in to do the water pumpl, you loose more money than you saved by cheaping out on a $60 maintenance item.

Every timing belt change as recommended by BMW.
