FAQs

How do you find a serpentine belt routing diagram? ›

Where can I find a belt routing diagram for my engine? A: Commonly a belt routing diagram sticker is on the underside of the hood or in the engine compartment. If there is no diagram, make a sketch of the belt and pulleys before removing the belt. This will help you re-route the new belt correctly.

EXAMPLE: 6PK1003 » 6 - This indicates the number of ribs on the belt; therefore, this is a 6-rib belt. » PK – The “P” indicates a metric designation, and the “K” indicates the belt is automotive per SAE J1459. » 1003 - This is the effective length of the belt expressed in millimeters.

If you put the belt back on in the opposite direction, the ribs end up in different pulley grooves than the ones they've adapted to over time. This means that the belt has to re-adjust to a new abrasion pattern, which will lead to a dangerous loss of belt tension.

Chattering or Squealing Noise: A chattering noise typically indicates a loose or seized pulley, while a squealing noise is a sign of a faulty bearing. Misalignment: Misaligned pulleys will cause belt chirp noise problems and are caused by worn bearings.

To check the alignment of the belt, place a straight edge or laser alignment tool across the face of the pulleys, making sure it touches both pulleys. Then, move the straight edge or laser to the side of the belt and check for any gaps between the belt and the straight edge or laser.

If the belt is already out of place, locate the driver's manual or the under-the-hood placard, where you'll find a sketch of the routing.

Misalignment pulleys or tensioner: If the belt is not properly aligned on the pulleys, it can wear unevenly or slip off entirely, leading to its premature failure. This situation usually happens if some of the components have been previously removed, replaced, and not returned in to place properly.

Clockwise means that you start at the loop just to the right of the button and end at the loop just to the left, whereas counterclockwise is the other way around. Traditionally in the US, men thread their belts counterclockwise and women thread their belts clockwise.

you may need to install it and tighten it down enough so that you can just barely move it and then swing it back and forth to create rub marks. If you torque the pivot point and it still rotates and only when you attach the piston it doesn't move then the tensioner is bad.

Excessive Wear: A serpentine belt that is too tight can cause excessive wear on the belt and other components, leading to premature failure. The added tension can cause the rubber on the belt to wear down more quickly, which can cause the belt to crack or break.

What are the symptoms of a bad idler pulley? ›

The idler pulley is a component that supports the movement of your vehicle's drive belt. Common symptoms of a malfunctioning idler pulley include corrosion on the pulley's surface, chattering and squealing noises, and slow spinning. Recommended idler pulley brands include Replacement, Gates, and Dayco.

The tensioner pulley is responsible for keeping the belt tense while making sure it stays aligned the entire time you're driving. While the location of the tensioner pulley can vary depending on the vehicle, you can usually find it at the end of the tensioner, which is typically connected to the accessory drive belt.

You can find the correct size of serpentine belt for your car in the owner's manual or by using an online belt sizing tool. If you are unsure about the size of the serpentine belt you need, it is best to consult a mechanic or an auto parts store.

To do this, the belt has to be twisted 90 degrees. Twist it one way, and drive it from the appropriate side, and it'll go one way; twist it the other way, so you can drive it from t'other side, and it will go in the opposite direction.
