How do you determine pulley size?
Place your pulley face down on a flat surface, then put your ruler or caliper on top, measure from outside edge to outside edge across the circle of the pulley. Check carefully to make sure you are measuring across the center.
Does pulley size make difference?
A larger diameter pulley wheel (aka sheave) is technically more efficient than a smaller diameter pulley. But it’s a trade off: a larger pulley has increased bulk, weight and cost. This efficiency increases with really big loads (600 lbs+) and larger mechanical advantage, such as 6:1 and 9:1.
Where do I find the serpentine belt routing diagram?
Find the serpentine belt routing diagram. Many cars come with a sticker in the engine bay that shows exactly how the serpentine belt is supposed to be routed through the various pulleys on the engine. If your vehicle does not have a sticker, you will need to find another way to remember how the belt should be run.
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.
How do you remove a serpentine belt from a car?
Pull the belt off of the pulleys. With the tension relieved from the belt, pull it off of the pulley that has been placing tension on it, then remove it from the around the rest of the pulleys on the engine. If the belt is severely damaged, be sure to remove any parts that may have come off of it as well.
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.

How do you measure the size of a serpentine belt?
With the string tightly wrapped around the correct path of the serpentine belt according to the diagram in your owner’s manual, mark the area on the string with a marker where it completely wraps around. Measure the length of string it took to wrap around the path of the serpentine belt.
What happens when you change the serpentine belt?
Billions of rotations under constant tension of the serpentine belt will take its toll over time. The “ribs” in the pulleys get damaged so even if you change the belt, the damaged pulley will tear and shred the belt again.
Can a car run without a serpentine belt?
However, these devices cannot function properly without the help of a serpentine belt. This one long continuous belt is the force that drives many of the engine’s peripheral devices. There is usually a belt tensioner or idler pulley to guide the belt as it moves. What is a Serpentine Belt? What is a Serpentine Belt?
