Firstly the car must be a 96' to be a 2.0lt or it must be an 1800
being the nearest to a 2 lt.
The water pump is not driven by the timing belt.

Yes it could be that but could also be alternator bearing as well.

This is probably driven by the timing belt. If your rattle/grinding noise is from the timing belt end of the engine then it could be the water pump or timing belt roller/tensioner. Probably best you dont drive it until you find the cause.
