Monterey Bay Monterey Bay Aquarium Though it's an ever-popular tourist destination, there's more to the Monterey Peninsula than a cool aquarium and an epic golf course.
First of all if the timing belt  breaks it can hurt the engine. A value can be open when it should  closed and it can be hit by the piston. â¦ The serpentine belt  breaking and wrapping around the crank shaft is HIGHLY unlikely to  cause the timing belt to break. The crank shaft supplies the pull  and push to the timing belt not the cam shaft. You would have to  cause the crank to stop immediately to have any chance of it  breaking the timing belt.
Serpentine belts typically last approximately 4 years or 40,000 miles.If you have put that many miles on in two years, it may be time. If you trust your mechanic, follow his/her advice and replace it. If not, get a 2nd opinion. You also may want to confirm it is the serpentine belt and not the timing belt.
