How to find the right Automotive Replacement Special Drive Belts AI guide

What the AI looks for in Automotive Replacement Special Drive Belts
- Stretch-fit identification
- If the drive has no tensioner on that belt, as is common on A/C or alternator drives on many newer cars, it needs a stretch-fit or elastic belt. A standard belt cannot hold tension without a tensioner and will slip or fail to install.
- Installation tool
- Use the manufacturer's install tool or the tool supplied with the belt. Do not lever the belt on with a screwdriver. Prying damages the internal cords, and the belt then loses tension quickly.
- Exact OE match
- Cross-reference the OE part number, because the length is designed around a specific amount of stretch. Stretch belts have no adjustment range to make up for a near-match.
- No reuse
- Treat a removed stretch-fit belt as single-use. Once it has been stretched off, it will not hold its designed tension.
Brands that matter
- Gates: Stretch Fit belts, often supplied with an install tool.
- Dayco: Stretch belt line covering many European and Asian applications.
- Continental (ContiTech): Elastic belts, and the OE supplier for many European makes.
What to avoid
- Substituting a standard ribbed belt of the same length
- Reinstalling a stretch belt you removed to reach another component
