1995 Buick Park Avenue Two Wheel Drive Automatic
My wife was pulling into a driveway the other day when she lost power stearing. I checked the car out and found that the serpentine belt was off and the power steering pump was hanging by the hoses.
About 1,500 miles ago I had the water pump and serpentine belt replaced by a shop. I checked my Haynes manual and it suggested that to access the water pump you could remove the power steering pump.
I suspected that maybe the shop did this and either over torqued the bolts on the power steering pump or left them loose. At any rate, I never heard of a 2 mounting bolt just breaking off of anything like that.
I took it back to the shop that did the work. They claim that the serpentine belt tensioner froze and that caused so much tension on the power steering pump that the bolts sheared.
This sounds bogus to me. I thought that the tensioner just took up slack. I dont see how it could add tension. I also believe that there would be bearing noises, or that the bolt on the tensioner pully would give way before 2 mounting bolts.
May I ask your opinion?
have the same problem?
