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.

Most vehicles nowadays usually have a belt routing sticker located somewhere in the engine compartment, making it even easier.

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.

Depending on the engine in your vehicle, the serpentine belt may be located at the front of the engine bay, or it may be along one side. There may be engine covers in the way, so be prepared to remove them if need be.

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.

Serpentine is best kept to those inner layers.

Individual byte lanes want to use the same routing layers so that all of the signal integrity problems are equalized. Taking away variables makes the timing and impedance calculations simpler. Length matching starts with making the long tent-pole as short as possible.

The serpentine belt is a long rubber belt that transports power to the engine accessories—the alternator, power steering pump, air conditioning compressor and (sometimes) the water pump. Sometimes the serpentine belt is called a drive belt, fan belt or accessory belt.

Just like the old V-belts, any check should start with examining both sides (the flat and the ribbed) for cracks and shiny spots, which indicate a slipping belt. Also, check for oil, coolant, and power steering fluid contamination of the belt; some chemicals can rapidly degrade the rubber.

Take your existing pants size and then add two inches to the number. For instance, if your pants waist size is 38, then your belt size would be 40.

You can immediately tell the distinction between the two belts when you look at the ribs on the belt. A timing belt has horizontal "teeth" that are made to fit both the crankshaft and camshaft. In contrast, a serpentine belt has multiple V-shaped grooves that appear vertically along the belt.

How do you identify a V belt pulley? ›

How To Identify a V-Belt Pulley. The easiest way to identify a V-belt pulley is by finding the part number or identification components on the pulley itself. Different brands, as well as different pulley types, have various ways they may display these numbers.

What Is the Ribbed Belt Profile and Number of Ribs? Ribbed belts have lengthwise grooves on the inside. Measure the pitch of the groove, i.e. distance between projections, e.g. 3.54 mm = belt type PK. Count the number of grooves, i.e. the number of projections - e.g. 7, as shown in the picture.
