Hello. According to my resources, the serpentine belt size for your vehicle with the 3.9 liter engine is 97.3 inches long and 0.96 inches wide. The belt should also have seven grooves in it. The Dayco part number for this serpentine belt is 5070973 although there are several other brands and options available to you. If you decide you’d like to have this done for you, a technician from YourMechanic can replace the serpentine belt for you at your home or office.
