Is the water pump driven by the serpentine belt?

Another important device driven by the serpentine belt is the water pump. This is not always the case as on a lot of cars the water pump is driven by the timing belt. You should have this in mind so you don’t falsely “accuse” the serpentine belt for overheating.

Why does my serpentine belt make a screeching sound?

The belt slides over a motionless pulley causing extensive friction, heat and the recognizable sound. The screeching sound may also be caused by a severely worn out serpentine belt (in this case, it must be nearly pulverized).

What causes a belt to squeak over pulleys?

Squeaking is caused because the belt is slipping over the pulleys. The slipping is caused because the belt loses ability to produce enough friction between itself and the pulleys (mostly due to material fatigue).

What should I do if my serpentine belt fell off?

If the battery warning light comes up while driving, the serpentine belt is the first thing to check. There are two “glow levels” of the battery light if you have a serpentine belt problem: This is the case if the belt snapped or fell off.

Why does my serpentine belt slip in the morning?

Very small amounts of water appear on the serpentine belt in the morning acting as sort of lubricant, causing the belt to slip. This, combined with the beginning of belt material fatigue will cause this sound. It usually disappears once the belt warms up a bit (like 10 to 20 seconds after the engine is started).

Can a loose serpentine belt cause an alternator to whine?

If the belt is too loose to maintain grip on the alternator pulley, you may experience a similar symptom as a snapped belt. If you start to notice a whine from the engine that changes with engine speed, you may want to have the tension of the serpentine belt double checked.

What kind of pulley does a serpentine belt use?

Determine if there is a belt tensioner pulley. Depending on the application, your serpentine belt will either have tension placed on it using a movable bracket or an auto tensioner pulley. This pulley uses an internal spring to apply consistent pressure to the belt at all times.

What causes a pulley belt to be shredded?

RAY If you’ve had one of the accessories replaced recently — like the alternator or water pump — I’d suspect that that pulley is now lined up incorrectly. It could have been manufactured incorrectly, or it could have been the wrong pulley for your engine. A pulley only has to be a few millimeters off to set a belt a-shreddin’.

Can you replace serpentine belt on Audi A4?

On the A4 it had a 17mm nut which you turned to push and swing the tensioner pulley and release the belt. Once you had done it a couple of times it was a 2 minute job! Sorry, yes, the ‘long’ bolts replace yours and it acts as you say like a sliding rail. Coolant pipes and wiring etc will ‘stretch’ enough to avoid uncoupling.
