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
