When is it time to replace an alternator pulley?
When is it time to replace an alternator pulley?
Alternators take quite a bit of power to run so good belt contact with the pulley is very important. If you have poor belt wrap or your pulley becomes “glazed” a glazed pulley looks very smooth it may be time to replace the pulley. Quality alternator pulleys are very important. Many OE manufactured pulleys are made from stamped sheet metal steel.
What are pulleys for alternators made out of?
Quality alternator pulleys are very important. Many OE manufactured pulleys are made from stamped sheet metal steel. These pulleys have a tendency to heat up and warp which will cause premature belt wear, pulley “glazing” and belt failure.
What causes an alternator pulley to squeal in a car?
Most modern cars use a serpentine belt system that is tensioned by an automatic belt tensioner, which cannot be adjusted manually. In these cars, problems with the belt tension are often caused by a worn belt that has stretched.
Can a belt wrap completely around an alternator?
If the belt were to wrap completely around the pulley that would be 100% belt wrap. having 100% belt wrap completely around the alternator would be impossible but the greater the belt wrap the longer belt and pulley life can be expected. Alternators take quite a bit of power to run so good belt contact with the pulley is very important.
Where does the serpentine belt go on an alternator?
If you do not have a diagram on the vehicle or in your service manual laying out the direction your serpentine belt travels through the pulleys, take a picture of it with your phone to refer to when installing the new belt. A strictly alternator belt will likely only go around an alternator pulley and the crank pulley at the bottom of the engine.

What’s the best way to loosen an alternator belt?
Use a breaker bar or socket wrench to loosen the auto-tensioner. Many newer model vehicles come equipped with an auto-tensioner pulley. The pulley presses upward as the belt wraps around it so the belt remains under constant, steady tension.
Why does an alternator pulley affect the charging?
Also, because your alternator is spinning faster the fan will move more cooling air through the alternator adding to component life, to little air flow can burn up an alternator. Alternator pulley belt wrap, what does that mean?
What happens if I change the pulley size on my lternator?
Caution must be noted: Changing the pulley size on your a lternator may void the manufacturers warranty. Spinning your Alternator faster will increase brush and bearing wear.

What happens if you spin your alternator too much?
Spinning your Alternator faster will increase brush and bearing wear. Using a smaller pulley on a high revving engines can cause component failure from extreme speeds.Alternators are only good for about 15,000 continuous RPM’s, the lower the alternator RPM’s the longer your alternator will last.
What happens when the belt on an alternator breaks?
A closer observation of the alternator will reveal a pulley and belt system that works to convert mechanical energy into electrical energy. The serpentine belt powers the alternator, and if it fails, the alternator will stop working the moment your belt wears out and breaks, or the pulley becomes damaged.
