This is in response to all that have posted messages to me..... the cars belt was replaced at the recommended 70,000 miles, at that time and year it was not recommended changing the pulley. Now the car has 109,000 miles and the pulley broke, damanging the engine. I have called Volvo and was VERY dissapointed in there response. I have spoken to the customer service rep and now he will not return my calls. If in fact there have been problems why wasnt any letter or notification sent to me? I have taken great care of the car, and always on time. So now I am 4000.00 dollars short and have a rebuilt engine. I am trying to get info to take action on this problem. Thanks to everyone that responds. Also the mechanic that works on my car use to work at a dealership , and knows his Volvos.
