What is a PK Number?

A PK number is a code that indicates the dimensions and design of a serpentine belt. It is usually found printed on the belt itself and serves as a quick reference for replacement parts. Understanding how to read this number can save you time, avoid mismatches, and ensure your vehicle runs smoothly.

Breaking Down the PK Number

The PK number typically follows a format that includes:

1. PK: This prefix stands for “Poly-K,” denoting the belt’s design. It indicates that the belt is ribbed and has a unique profile that allows for better grip and performance.

2. Numerical Values: Following the PK prefix, you’ll usually see a set of numbers. These numbers represent the belt’s length (in millimeters) and width. For example, a belt labeled PK 1230 would have a length of 1230 mm.

3. Additional Letters: Sometimes, you may see letters and other codes that further specify features like the belt’s material or intended use, such as “R” for rubber or “S” for a specific strength rating.

Why is the PK Number Important?

Knowing how to read a PK number on a serpentine belt can:

• Ensure Correct Fit: Using the right PK number guarantees that the new belt will properly fit your vehicle.
• Enhance Performance: Installing a belt with the correct specifications can improve engine performance and prolong the lifespan of other components.
