Your car's accessory belt needs the proper amount of tension in order to function effectively. The tension applied on the belt comes from the accessory belt tension pulley. When looking for a high-quality belt tensioner pulley, you need to look into the do's and don'ts to avoid getting the wrong one.
- Refer to your vehicle's manual for your car's belt tensioner pulley specifications. If you don't have the manual with you anymore, there's always the internet to search on. Just make sure that you get the data from a trusted online source, such as your car manufacturer's website.
- Check which flange is suitable for your vehicle. Getting the right match ensures compatibility. To identify the flange suited to your pulley, you need to know your pulley's width, and its inner and outer diameters. Two types of flanges for the belt tensioner pulley are steel and polymer.
- Look for a belt tensioner pulley with lubricated ball bearings and double high temperature. These features offer peak bearing performance.
- Go for a belt tensioner pulley that's covered with a long-term warranty. The usual warranty period is 1-year with unlimited-mileage.
- Don't buy a driver's side belt tensioner pulley if you're looking for a passenger's side tensioner pulley replacement. This can lead to accessory belt malfunction, which in turn, can cause engine damage.
- Don't purchase a used belt tensioner pulley unless you've assessed its remanufacturing origins. Be suspicious of overly cheap used tensioner pulleys as these are most likely damaged. Check your supplier and the actual belt tensioner pulley before buying it.
- Avoid getting low-quality belt tensioner pulleys in exchange for a cheaper price. When you examine the situation carefully, these low-quality pulleys break faster and require replacement more often than standard ones. Therefore, the sum of adding up the costs of numerous low-quality pulleys is equal or even greater than the price of one high-quality pulley.
