Winner of Import Vehicle Community 2017 Best Mobile App for Application of Import Cars or Trucks @AAPEX-Show and a 2012 Popular Mechanics Editors Choice Award.

Dayco, a leader in the research, design, manufacturing and distribution of a broad range of belts, tensioners and pulleys for the automotive, trucking, construction, agricultural and industrial markets, introduces the “Dayco App” for mobile and tablet devices.

Using state-of-the-art scan technology, scan your VIN with the smartphone’s built-in camera for immediate access to a complete list of Dayco parts that match your vehicles year, make, and model.

Whether you are a professional mechanic, do-it-yourselfer, or work in a retail location, you can also search Dayco parts by category, manually entering the VIN number, or referencing saved vehicles under My Searches. You can also enter another company’s part number and find the Dayco part equivalent. If you have a Dayco part and need specs, routing instructions, or brochures, simply enter the Dayco part number for an instant list.

For those that need to visit or call a retail location, click the Where to Buy tab and find a location near you. The Learning Center provides multiple resources for belts, tensioners, and hose applications. Make a quick call or send an email to Dayco at the tap of a button.

The Dayco app is simple to use, offers comprehensive tools for every need, and the results are immediate. Application information is provided for auto and light trucks, ATVs and snowmobiles, heavy duty, hydraulic, industrial, and lawn and grounds.

Ratings and Reviews

States Are Mixed Up

Elliott Roundtree

This app is great. With the recent update, some states are reversed with another state. Ex. Arizona shows (AR) and Arkansas shows (AZ). You have to select Arizona to look at Arkansas plates. Not all are like this, but other states have similar problems. Thanks!

Developer Response

Thank you. Fixed with new version 4.2.0

Finally an app that really helps

Brett Swearingen

This app is great. I scanned the vin on the inside of my door panel and all of my parts instantly pulled up on my phone. There's even an how-to-install video for some of my parts. I needed to replace the belt that came with my car and it was really easy to find the Dayco equivalent part. All I had to do was key in the part number and viola it was there. The really cool thing is that I can store my cars and parts on the app. This app is easy to use and a big help.

This app is extremely useful. I work for a parts store, and this can come in handy when I'm on a delivery to help my commercial customers locate the belt or pulley they need. It's fast and easy to use, just scan or enter the VIN number of the vehicle you need the part for, and it will give you the part number for every part Dayco sells for that vehicle.
