What this belt is and who fits it
The DAYCO 15390 is a replacement V-belt built to industry number 11A0990. It suits engines that call for a cogged belt with a 39 in outside length and a .44 in top width. Mechanics and DIY owners use it to drive accessories such as alternators, water pumps or power-steering units on compatible applications.
Heat, noise and tension in service
A cogged profile reduces bending stress so the belt runs cooler and quieter than a wrapped equivalent under the same load. The moulded notches improve grip on small pulleys, lowering slip and the squeal that comes with it. Correct tension keeps power draw at the accessory within specification.
What the cogged design changes for you
The notched construction lets the belt wrap tighter radii without cracking, which matters on compact drives where a standard V-belt would bind. No special tools or matching pulleys are required beyond the original equipment spec. The transparent colour simply shows the cord layout during inspection.

Questions about this item
How do I install the DAYCO 15390 V-Belt and what step is often missed?
Route the belt around each pulley following the engine's routing diagram, then apply tension. The step often missed is verifying the cogged profile seats fully in every pulley groove before final tightening.
What maintenance or replacement will the DAYCO 15390 V-Belt need later?
Inspect the belt at each oil change for cracking, glazing, or missing cogs. Replace it immediately if the 0.44 in top width shows uneven wear or if squealing appears under load.
What limit appears first on the DAYCO 15390 V-Belt during sustained use?
Heat buildup from continuous operation degrades the rubber compound, leading to cog cracking or belt stretch that reduces tension on the 39 in outside length.
