The Dayco E040312 is a stretch-fit automotive multi-rib belt with 4 ribs and a width of 13.72 mm. Its length is given as an effective length. This page covers how to match it to the belt you are replacing.
The most reliable way to match this belt is to read the marking on the back of the old belt. Look for the Dayco part number E040312, or the alias 4PKE794. If the old belt is worn or the marking is gone, count the ribs and measure the width. This belt has 4 ribs and a width of 13.72 mm. Confirm the profile and the effective length before ordering.
Because this is a stretch-fit belt, it is designed to be installed without a tensioner in many drives. Do not force a belt that does not match. If the old belt has a different number of ribs or a different length, it is not the same part. When the marking is unreadable, send a photo of the old belt and the drive layout. We can help confirm the correct belt or suggest an equivalent.
