How did we estimate these prices?
Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair.

What parts do I need for my timing belt tensioner replacement and how much do those parts cost?
You can check your owner’s manual or ask your mechanic for precise parts, but here’s a general rundown:
- Timing belt tensioner: The timing belt tensioner is the main component in the replacement. The timing belt tensioner is responsible for maintaining the appropriate belt tension, preventing slippage, and ensuring smooth operation. On its own, a timing belt pulley costs anywhere from $20 to $125.
- Timing belt: When replacing your timing belt tensioner, your mechanic may determine that the entire timing belt needs replacement. A new timing belt typically ranges from $15 to $400.
- Timing belt pulley: The primary function of the pulley is to keep the timing belt aligned as it rotates around the crankshaft and camshafts, ensuring perfect synchronization. Individually, the cost of a timing belt pulley ranges from $35 to $80.
- Crankshaft and camshaft seals: These seals safeguard against oil leaks from both the crankshaft and camshaft. It’s advisable to replace these seals when performing a timing belt tensioner replacement while the engine is disassembled. Typically, crankshaft seals are priced at $10 to $60, while camshaft seals are available at prices ranging from $5 to $35.
- Water pump: The water pump is integrated into the cooling system and is operated by the timing belt. Once the timing belt is taken out, you can easily access the water pump. While it’s not necessary, consider replacing the water pump simultaneously with the timing belt pulley to prevent potential future labor expenses. The typical price range for a water pump is approximately $45 to $150.
We recommend purchasing these parts at local auto parts stores like AutoZone, Advance Auto Parts, and NAPA Auto Parts, as well as online retailers like Amazon and RockAuto. We also recommend reputable brands such as Gates, Aisin, Continental, and SKF to ensure a reliable and successful replacement. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.
Should I buy an OEM or aftermarket tensioner?
When considering replacing your timing belt tensioner, it’s a good idea to choose an aftermarket option instead of an OEM (original equipment manufacturer) one. In many cases, aftermarket timing belt components are not only more cost-effective but also tend to have a longer lifespan.
Where can I buy a timing belt tensioner replacement?
Timing belt tensioners can be found at automotive body shops and auto parts stores such as AutoZone, Advance Auto Parts and NAPA AutoParts but you can also buy them online from Amazon and RockAuto.
Important note: Your vehicle's owner manual contains all the specifications for replacement parts, which can guide you in finding the correct ones.
It is also worth mentioning that if you need to replace more than just the timing belt tensioner, it’s best to purchase an entire replacement timing belt kit.

How will a mechanic replace my timing belt tensioner?
Here’s how a certified and experienced mechanic will carry out this repair for you:
- Verify that the timing belt tensioner is the root of the problem.
- Gain access to the timing belt tensioner. This typically involves removing the timing cover, timing belt pulley, and the timing belt itself.
- Remove the bad timing belt tensioner and install the new one.
- Reinstall the removed components (or replace them with new parts). The timing belt and idler pulley retaining bolt need certain amounts of tension, and elements of the timing system need to be aligned correctly, as the timing belt goes in.
- Perform an engine test and then road test the vehicle for good measure to make sure everything is working perfectly.
What happens if I don’t replace my bad timing belt tensioner?
If you notice any problems with your timing belt tensioner, or your timing belt in general, you should act swiftly. A bad timing belt tensioner that is ignored can cause the following issues:
- Lower engine power, overheating engine, engine misalignment, misfires, or complete engine failure
- Timing belt failure
- Increased wear on other parts
- Inability to start the vehicle or a sudden stop while driving
- Costly repairs (which can exceed $1000)
What is a timing belt tensioner?
An engine’s valves, pistons, and crankshaft need to work in harmony together, with perfect timing. The timing belt makes sure that happens, running between all these important systems and keeping everything synchronized.
With time, however, timing belts expand as they get warmer and stretch out, which only worsens with age. The timing belt tensioner applies force to the timing belt, either through springs or hydraulics, to keep it firmly in place as it stretches out.
Pro tip: Your mechanic will likely recommend replacing your timing belt, water pump, and front seals when the timing belt tensioner gives out. It’s more expensive, but doing this now can save you money on labor costs later and prevent other problems too.
When should I replace the timing belt tensioner on my car?
Here are some of the warning signs of a bad timing belt tensioner:
- Chirping, squealing, or rattling sounds, especially if they’re high pitched. Chirping sounds are usually belt-related, but keep in mind weird noises coming from your engine can mean all sorts of different things.
- Rough engine performance is a later-stage warning sign.
- Engine stalling or not starting. If the timing belt tensioner is too loose, the engine will have a hard time starting or might not start at all.
Keep in mind: These signs can vary depending on your car and its engine type. It's always best practice to consult your owner’s manual or ask a qualified mechanic to assess the condition of your tensioner.
How often should a timing belt tensioner be replaced?
There’s no recommended timeline when it comes to timing belt tensioner replacement. That said, you should generally replace your timing belt (and this often includes your tensioner) every 60,000 to 100,000 miles.
Keep in mind: Every manufacturer specifies a different age or mileage limit for their timing belt parts, so be sure to refer to your owner’s manual or consult with a certified mechanic.
Pro tip: For prevention purposes, make sure to inspect your tensioner each time you service your vehicle in order to monitor its condition.
Can I replace my timing belt tensioner myself?
While you can certainly attempt to replace your timing belt tensioner on your own, you need to be confident in your auto repair and DIY skills. Replacing this part is a somewhat complicated procedure that requires direct interaction with your engine.
For the average driver, we recommend seeking the assistance of a professional mechanic.
