Summary
  • The tensioner pulley is responsible for keeping the belt tense while making sure it stays aligned the entire time you’re driving.
  • While the location of the tensioner pulley can vary depending on the vehicle, you can usually find it at the end of the tensioner, which is typically connected to the accessory drive belt.
  • In most cases, accessing the tensioner pulley also means accessing the tensioner. Before you can get to the tensioner, you’ll have to loosen and remove the belt from the alternator first.

Q: Where is the Tensioner Pulley Typically Located?

A: While the location of the tensioner pulley can vary depending on the vehicle, you can usually find it at the end of the tensioner. Typically, the pulley is considered part of the tensioner, although the pulley can be replaced by itself on some platforms. If you’re looking for the tensioner pulley, then locating the tensioner, which is typically connected to the accessory drive belt, is a good place to start.

On most 2007-2011 Toyota Camry models, you can find the tensioner and pulley right next to the alternator under the hood. The same goes for 2005 Honda Odyssey models, except the drive belt system isn’t located under the hood. Instead, it’s only accessible through an opening behind the front wheel on the passenger’s side.

The tensioner pulley is responsible for maintaining belt tension all while making sure it stays aligned as it travels around the pulleys.

You also need to hold it while you remove or install the belt. | Image Source: Richard McCuistian

Tips on How to Access the Tensioner Pulley

In most cases, accessing the tensioner pulley also means accessing the tensioner. Before you can get to the tensioner, you’ll have to loosen and remove the belt from the alternator first. Once the belt is out of the way, you can now unscrew the tensioner and remove the pulley.

Sometimes, accessing the tensioner pulley can be a little more complicated than that. On cars like the 2005 Honda Odyssey, you’ll have to jack up the front passenger’s side of the vehicle and remove the tire to gain access to the drive belt system.
