This DAYCO Multi Ribbed Drive Fan Belt is a Poly-V Belt designed for auxiliary applications. It features 3 ribs and a length of 576.0 mm, with the part number 3PK576EE. Multi-ribbed poly-V belts offer larger contact areas than traditional V-belts or flat belts, allowing for greater power transmission. This translates to reduced energy costs and quieter operation compared to flat belts. It's important to regularly inspect and replace belts showing signs of wear and tear, such as cracking, which can occur due to continuous exposure to high temperatures and bending stress around pulleys. This is a brand new OE quality Dayco belt.
