One item that should be checked at every service is your serpentine belt. Why do you ask? That’s simple. Your serpentine belt is an important function of your automobile. It is used to keep your power steering pump, alternator, water pump, and air conditioner running. Now it’s not an item that will need to be replaced every single service, but it is one that should be checked for any fraying, cracks or wear that may cause it to break or come off. Having your serpentine belt break will cause you to lose power and possibly control of your vehicle and can result in engine damage. Let’s face it…A German automobile isn’t the cheapest repairs in town. With every oil service, we provide a complimentary safety inspection. At Autohaus Frankfurt we treat our customers German luxury vehicles like they are one of our own.
