Audi Serpentine Belt Replacement in Peoria

The serpentine belt is how your engine powers accessories such as the alternator, air conditioning compressor, power steering pump, water pump, and in some vehicles a supercharger. This single belt is driven by the crankshaft pulley and winds its way around to each accessory. While the serpentine belt is a very sturdy component that can generally last 50,000 miles or more, it will still wear over time and start to slip. If this happens, I can cause your accessories to perform poorly. Review your Audi owner’s manual or contact our Audi service center for the serpentine belt replacement schedule for your specific Audi vehicle.

When Should I Replace My Audi Serpentine Belt?

Most serpentine belts last for 50,000 miles or more. Consult your Audi owner’s manual for details on your specific vehicle. Symptoms that point to a failing serpentine belt generally appear as poor performance from accessories, rather than driving performance. Common symptoms include:

  • AC is weak or does not work
  • Squealing noises may mean the belt is slipping and/or causing a pulley to wobble
  • Loss of battery voltage or the alternator failing to charge the battery
  • Power steering failure
  • Overheating engine
  • Cracking or fraying on the edges of the belt
  • Teeth on the belt appear worn down

Audi Timing Belt Replacement in Peoria

The timing belt on your vehicle is critical to keeping your engine running smoothly. Timing belts link your crankshaft to the camshaft; enabling it to open and close valves. This ensures that the valves and pistons stay in rhythm and allow air in, and exhaust out at the correct intervals. Should this belt break, pistons and valves may collide within the cylinder, causing serious if nor irreparable damage to the engine.

When Should I Replace My Audi Timing Belt?

As a precaution, Audi recommends changing a timing belt many thousands of miles before the part reaches any risk of failure. Generally, this replacement interval is between 50,000 and 100,000 miles. Consult your owner’s manual or contact our service department for information regarding your specific vehicle’s service recommendations.
