Serpentine Belt Fan & Idler
This is the cogged version of the revolutionary multi-ribbed belt first developed by Dayco for the 1979 Ford® Mustang®. The multiple-rib design provides better belt-to-pulley contact for less slippage, so it lasts longer than conventional V-belts. Multiple ribs also eliminates the need for matching, and allows controlled slippage in shock overload situations, such as when the AC compressor kicks in.
Daycos superior manufacturing technology uses a rubber-impregnated fabric backing that maximizes load-carrying capability and minimizes the noise that is often associated with the competitions rubber-backed belts. Poly Cog belts meet or exceed SAE J1459 and J1596 specifications.
* Dayco Poly Cog belt part numbers identify the size and length of the belt. Here is an example; 5080565
5 = Dayco Poly Cog Belt
08 = Number of Ribs
0565 = 56.5 Effective Length
