dirt and dust usually could possibly be a dry worn belt but also check the belt tensioner it can be to weak and allow squeaking

Also, sometimes a belt with small cracks in it will make noise. If you haven't replaced the belt for a while I'd be suspicious of the cracks.

I've had this happen...check to make sure that water or anti-freeze did not hit the belt.

Either the belt is worn out or the tensioner is defective.

This also may be caused by your pulleys. For instance if the harmonic balancer gets out of line with the rest of your pulleys it can cause a squeak or if the bearing in one of your other pulleys has gone bad it can cause a squeak also.

A squeaky belt is usually caused by a bad belt, a missaligned pulley, or something leaking on the belt.

Yes, as long as there is no damage to it

In the newer vehicles the serpentine belt drives all the pumps, compressor and the alternator on the engine.

You have a mechanic check for proper belt tension. Trust me, in the long run this is the smartest, safest and CHEAPEST way to solve the problem.

Serpentine means "snake-like". The serpentine belt is the belt found on many vehicles that "snakes around and runs key components such as alternator, waterpump, power steering pump and air conditioner. It is a single belt that runs multiple components as opposed to vehicles without serpentine belts which usually have separate belts for each component. ie. alternator belt, power steering pump belt.

No vehicle is specified, however, in all vehicles I have seen and/or worked on, the serpentine belt must be removed from the pulley that spins the alternator. NOTE: Some vehicles have another, separate, serpentine style belt that runs the a/c compressor and may have to be removed to remove the belt running the alternator. (Complete removal is not necessary unless the belt needs to be replaced.)

With engine off try putting a small dab of silicone grease on each side of the belt. It works for me.

Serpentine belt. If its cracked, frayed, or worn replace it before it breaks or you're in for a hefty repair bill.

User Avatar

the belt is ether too old, or a faulty component that is being driven by the belt.

Check the allignment of all the pully's.

No, an accessory belt is not considered a serpentine belt. However, a serpentine belt is considered a specific type of accessory belt.

User Avatar

it could be a serpentine belt or accessory belt.

User Avatar

Yes, like most modern vehicles, the serpentine belt runs the water pump, power steering, alternator and the air conditioning compressor.

User Avatar

The serpentine belt would be the same as the accessory drive belt.

Getting the serpentine belt onMost vehicles don't require you to remove parts to install the serpentine belt. Most vehicles have a diagram on the hood or under the hood showing the proper alignment and direction of a serpentine belt. There is a tensioner that must be pulled to allow you to install the belt. With out a 1/2" Socket wrench you will not be able to put the belt on your car. If you don't have a diagram and cant find the tensioner pulley I suggest asking a mechanic for help. Its not time consuming if you know what your doing. I can change my serpentine belt in 10 mins MAX, on my Lincoln caddy and x terra. None of them require removing a part.

Serpentine belt, no. Timing belt, good chance yes.

User Avatar

If the alternator belt is the same belt as the other accessories, yes.

User Avatar

That I know of, there is NO serpentine belt, unless you are talking about the the Timing Belt (hardly serpentine, but anyway), it has a belt tensioner, not automatic, though.

User Avatar

If it's a "chirping" noise, then you don't have the belt tight enough.

User Avatar

no as they have different names. No, the cam belt drives the engine cam and possibly water pump on some vehicles. The drive belt or serpentine belt drives the alternator, power steering pump, water pump, A/C compressor, & cooling fan on some vehicles.

Loosen the tensioner pulley. Slide the tensioner pulley to the right. The serpentine belt will come loose. Remove the serpentine belt. Reverse the process to install the new serpentine belt.

User Avatar

Begin by loosening the tensioner pulley on your 2000 VW. The serpentine belt will become loose when the tensioner pulley is loose. Remove the old serpentine belt and put the new serpentine belt on. Tighten the new serpentine belt with the tensioner pulley.
