How do you check the tightness of a serpentine belt?
Check the tension by twisting the belt and measure the twist margin. If the tightness of the belt is right, tighten the screw in place to assert the firmness. Put the cover of the pulley back in place. Turn on the engine and observe the vibrations of bearings and pulleys, plus the spinning of the serpentine belt.
What happens if pulley on serpentine belt fails?
The serpentine belt is routed around pulleys that drive your vehicle’s accessories. If a pulley on one of the accessories seizes or fails to turn it will likely destroy the serpentine belt, but it’s important to consider that a belt that’s too tight will often lead to seizing pulleys.
How does the serpentine belt work on a car?
As your engine runs, the spinning motion of the crankshaft is transferred to each of the accessory pulleys via the serpentine belt. If your vehicle is supercharged, the serpentine belt also powers the supercharger. Older engines have v-belts instead of serpentine belts.
What happens when you glaze a serpentine belt?
Glazing is easy to spot, as it will look shinier than the rest of the rubber the belt is made of. Glazing occurs as the belt passes over pulleys without placing enough tension on them to actually make them turn with the belt. If the grooves of the belt have glazed over, you’ll need to replace the belt.
How do you know if your serpentine belt is too tight?
If you notice any whine or “pulsing” sound from the alternator, your belt tension is too tight and will damage the alternator.
