Spooky sound: A loud squeal when you first start the car, or when you turn on the A/C or heat.
That noise usually comes from the serpentine belt, the long rubber belt that drives the alternator, the A/C compressor and often the water pump. When the belt is worn, glazed or loose, it slips and squeals, especially in cool, damp weather.
A squealing belt is inexpensive to replace. A belt that breaks can leave you without charging, cooling or power steering all at once. We check belts and hoses with every complimentary inspection. Call Franklin Automotive at 615-472-8052 or book at franklinautotn.com.
