If it has the original water pump, there will not be a stainless steel rail for the timing belt. Later pumps added this rail along with a slightly larger roller. Actually, the early pumps did not have a port for the turbo, so you can check that without removing the belt covers. If there is a plastic port on top of the pump suction near the lower radiator hose, then it is a later pump.

Rebuilt water pumps can go out anywhere from weeks to years after their installation. Ive had a rebuilt pumps seal go bad one week after driving, and even a NEW pump seal go bad in 2 weeks. It just depends on how well the rebuild was done.
You should replace your pump when you replace your timing belts if there is any sign of leakage, or any play in the pump roller, because the extra tension you put on a new belt tends to make an old water pump start leaking. Your timing belts should be replaced every 40,000-45,000 miles at the most so at that time you should check for pump problems.

Actually you shouldn't worry about the water pump near as much as you should the timing belts. If either of those belts slip or break, then you are looking at a very expensive repair bill because these engines are interference motors and the pistons will hit the valves and bend at least one but more than likely several. If you don't know the interval when the belts, rollers and water pump were changed, it's a best practice to change them now so you know it's not going to damage the engine even more. Each of us maintain our cars a little differently, but most of us change our belts every 30 to 35 thousand miles or two to three years whichever comes first. I pushed mine to fifty one time and I paid the price for it.
