What this belt is and who needs it
The DAYCO 15420 V-Belt is a new automotive cogged belt built to the industry 11A1065 standard. It measures 42 in outside length and .44 in top width. Mechanics and DIY owners use it to replace worn drive belts on compatible engines.
Who it suits and who should look elsewhere
This belt fits applications that call for the exact 11A1065 dimensions. Buyers who need a different length, width, or rib profile should look elsewhere. It is not for serpentine systems or for drives that require a raw-edge or banded construction.
The specification that decides fit
The industry number 11A1065, with 42 in outside length and .44 in top width, is the single specification that confirms whether this belt matches the drive. Verify those figures against the original part before ordering.

Questions about this item
What comes with the DAYCO 15420 V-Belt and is anything else required for installation?
The box contains the single V-Belt. No additional parts are included; ensure pulleys match the 11A1065 profile before fitting.
How do I confirm the 11A1065 industry number matches my engine?
Compare the 11A1065 code stamped on your old belt or listed in the service manual; this belt has a 42 in outside length and .44 in top width.
What does the 42 in outside length mean once the belt is on the engine?
It is the total circumference around the pulleys; the belt must span that exact path without excess slack or tension.
