97 LeSabre Water Pump Leak

My 97 LeSabre needs a new water pump because it is leaking. At the same time that the leak started I began to hear a new, fairly high pitched whining sound which I assumed was a bearing in the pump. The service shop
told me that the new noise is actually coming from the tension arm because the bearing on the tension arm's pulley is bad.
How could these two problems occur at the same time? Could coolant be leaking onto the tension arm, and could that cause the secondary problem?
Also, if coolant has been getting onto the belt for about a week, does the belt need to be replaced. The service shop thinks that they can salvage the belt.

It seems dumb to me to put the old belt back on. It isn't that expensive.

Parts can wear out whenever they feel like it. The car is pushing 8 years old. How many miles?
If the Water pump bearing is making noise you could possibly better pin point what component it is by using a listening device. This could also be used for altenator & tensioner noises to, you just need to be careful around the moving parts. Also slipping the belt off & spinning pulleys by hand may also let you know which one is noisey.
If The tensioner is higher than the water pump I doubt it would get wet.
Is the belt the orioginal? If the belt isn't to badly cracked you could probably get more time out of it, but seeing your car has that belt that goes around the motor mount It probably would be a good idea to get a new one seeing the water pump is being replaced.
Make sure it isn't your intake manifold gasket leaking on the side of the engine that the water pump is on.
Good Luck !
