The importance of the belts under the hood of your Audi vehicle can't be understated. Their job is essentially to move all the parts that have to move for the car or SUV you love to run right. There's a lot more than this to learn about them, though. Luckily, our auto parts store has answers to the kinds of questions most people ask about them frequently.
Audi Belts Q&A
What Types are There?
Your model can have three: a serpentine belt, drive belts (also called V-belts), and a timing belt.
What Do They Do?
Serpentine belts work with pulleys -- a crank pulley and an idler pulley, specifically -- and tensioners. They move many parts, in the alternator, the power steering, and other systems.
A drive or V-belt runs off the crank pulley. It can pass through many systems -- the radiator and water pump, for example -- helping move their parts as it does.
Timing belts help keep auto parts from colliding with one other. They do that by making sure that camshafts and crankshafts run in sync. Newer Audi models may have timing chains instead; they do the same job.
No belt is exactly permanent, though. One can go bad after a lifetime of use. Luckily, when that starts happening, there are signs that'll tell you.
What are the Symptoms of Bad Ones?
- For serpentine belts: shallow groove depths, cracking
- For drive belts: cracks, squealing, alternator problems, excessive tightness or looseness, and engine overheats
- For timing belts or chains: general damage
When Should They be Replaced?
- The serpentine belt: if you start seeing the above-mentioned signs. Otherwise, every 90,000 miles. (Be sure to monitor it by inspecting it every 60,000 miles.)
- The drive belts: when they start showing said symptoms.
- The timing belt: when its signs of failure become apparent. Otherwise, every 60,000 to 90,000 miles.
- The timing chain, if your Audi has one: likely never. It should last your engine's lifetime.
