My trusty 07 beast just passed 80,000 miles and is running great.
On a recent trip up to Hanover NH to visit my daughter at school the engine sounded louder then normal and seemed to groan at low rpm speeds.
We had a full car with 4 adults and full luggage, so I thought it was just the extra 500 lbs I was not used to carrying around.
But just with my skinny butt in the car it still is groaning a bit.
Performance seems the same, car is just louder a bit.
I read the post on the vvee belt noise, so I suspect that this may be my issue.
What is replacement time for the belt ?
