DAYCO 17400 Auto V-Belt 13A1015
The DAYCO 17400 is a cogged automotive V-belt designed for engine accessory drives. It suits mechanics and vehicle owners replacing a worn belt on compatible applications. The belt carries industry number 13A1015 and measures 40 inches in outside length with a 0.53 inch top width. It is supplied new and ready for installation.
Cogged design reduces heat buildup
The cogged profile allows the belt to run cooler by improving flexibility around small pulleys. This construction lowers operating temperatures compared with wrapped belts of similar size. Reduced heat extends service life and maintains consistent tension during normal engine operation. Quieter engagement results from the precise moulded cogs meshing cleanly with pulley grooves.
Transparent colour aids visual inspection
The transparent material lets technicians check for cracks, glazing or contamination without removing the belt. Early detection of wear prevents unexpected failure on the road. No additional hardware or software is included in the package. The belt installs with standard hand tools following the vehicle service manual.

Questions about this item
How do I route the 40 In DAYCO 17400 V-Belt around the pulleys and what tension step is often missed?
Follow the engine routing diagram, seat the cogged profile fully in each groove, then set deflection to the service manual spec — skipping the re-check after the first run-in is the common error.
When will the 13A1015 belt need replacement and what wear signs appear first?
Plan replacement at the manufacturer service interval; look for transverse cracks across the cog bases, glazing on the .53 In top surface, or chunking of the rubber ribs.
What limit appears first on the 17400 belt during sustained high-load operation?
Heat buildup in the cogged section accelerates rubber ageing, so the temperature limit of the compound is reached before stretch or tensile failure becomes critical.
