How do you find a serpentine belt routing diagram? ›

Some vehicles have the serpentine belt diagram located on a decal somewhere in the engine compartment. But if your car does not have a decal, you can easily look up the diagram in a repair manual or repair database. Another option is to take a photo of the old belt before removal.

The cost of changing the timing belt is a bargain when you consider the cost to replace the entire engine. Start thinking about changing the timing belt once you cross the 90,000-mile threshold. Check your owner's manual for details.

Place the gauge on the belt in the middle of the longest span between two pulleys. Then, apply pressure to the belt tension gauge by rotating the gauge handle or using a wrench to turn the gauge bolt. Keep applying pressure until the gauge indicates the proper amount of 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.

The first digit indicates an eight-rib belt, followed by “P” to identify metric belt sizing, and a “K” showing that this belt conforms to the SAE standard for rib sizing (3.56 millimeters wide for automotive-type serpentine belts). The final series of numbers is the effective length of the belt, given in millimeters.

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.

Serpentine Belt vs.

The timing belt is inside the engine and keeps the crankshaft and camshaft in sync. It ensures that the engine intake and exhaust valves open and close in time with the pistons so the engine runs smoothly. The serpentine belt is what keeps the engine accessories running smoothly and efficiently.

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.

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.

Check if the belt runs centrally on the pulleys. Any sideward movement or slippage can indicate misalignment. Straightedge or String Line: Place a straightedge or taut string along the faces of the pulleys to see if they line up perfectly. Any deviation from a straight line suggests angular or parallel misalignment.
