If your car is making a squealing noise, it may be time to replace the tensioner pulley. According to CarsDirect, your local repair shop will charge you an hour or two to replace one idler pulley. But if you have the tensioner pulley, serpentine belt, and all idler pulleys changed at the same time, it will likely add just one more hour to labor costs while completely replacing the serpentine belt system.
So, how long does it take to replace a tensioner pulley?
It will take an hour or two to replace one tensioner pulley at a local repair shop. However, if you have the tensioner pulley, serpentine belt, and all idler pulleys changed at the same time, it will likely add just one more hour to labor costs while completely replacing the serpentine belt system.
Let’s dig into it and find out what’s going on.
How To Replace A Tensioner Pulley?
If your car has a squeaky tensioner pulley, it’s important to fix it as soon as possible. The serpentine belt in your car powers the accessories, and if the tensioner pulley is damaged, it can cause the belt to slip.
To replace the tensioner pulley, you’ll need to disconnect the battery, remove the old pulley, and install the new one. It’s a fairly simple process, but it’s important to follow the instructions carefully.
Replacing the tensioner pulley is a fairly straightforward process, but it’s important to follow the instructions carefully to avoid damaging the new pulley. Here are the basic steps:
1. Disconnect the battery. This will prevent the engine from starting while you’re working on the pulley.
2. Remove the old pulley. You’ll need to remove the serpentine belt first, and then you can unscrew the old pulley from the tensioner.
3. Install the new pulley. Screw the new pulley into the tensioner, and then re-install the serpentine belt.
4. Reconnect the battery. Once the new pulley is in place, you can reconnect the battery and start the engine.

When To Replace A Tensioner Pulley?
There is no set lifespan for the drive belt tensioner, but it is generally recommended that you have it replaced every 10,000 miles or so. This is because the tensioner is responsible for keeping the serpentine belt tight, and over time it can start to wear down.
If you notice that your serpentine belt is starting to show signs of wear, it’s a good idea to have the tensioner checked as well. If it is damaged, you’ll need to replace the entire tensioner assembly, not just the pulley.
Keep in mind that you should also inspect the idler pulleys when you replace the serpentine belt. These pulleys are responsible for guiding the belt around its cycle, and they can also wear down over time. If you notice any damage, be sure to have the pulley replaced as well.
The serpentine belt tensioner should be replaced every 10,000 miles or sooner if signs of wear are present. The entire tensioner assembly, including the idler pulleys, should be replaced if any damage is found.
Why Replace A Tensioner Pulley?
The serpentine belt in your car powers the accessories such as air conditioning, power steering, and the alternator. Over time, the belt tensioner will lose its capacity to apply tension to the serpentine belt. Sometimes, the mechanism will weaken or seize up, causing the belt to slip off or break. If this happens, you’ll need to replace the tensioner pulley.
To replace the tensioner pulley, first loosen the tension on the belt. Then, remove the pulley, washer, and bolt. Install the new pulley, washer, and bolt, and tighten the tension on the belt. This process should take about 30 minutes.
