SOURCE: How to change a water pump on a 1999 Buick Century 3100?

the water pump on the 3.1 isnt to hard to change ...

1. Disconnect the negative battery cable.
2. Partially drain the cooling system into a suitable container.
3. Remove the drive belt guard.
4. Loosen the water pump pulley bolts before removing the drive belt. This should help keep the pulley from turning as the bolts are loosened.
5. Remove the drive belt. Remove the water pump pulley bolts and remove the pulley.
6. Remove the water pump bolts and separate the pump from the engine front cover.

I had a 1987 Century and when mine started acting like that I took it to a garage and they hooked it up to a computer tester for free. Is she getting the check engine light coming on? They found that mine was running (lean) which ended up being my fuel pump. Which is in the gas tank and can be pricey to get done, between $250-$350 and of course the filter would get done at the same time and that is only$20
