Replacing a timing belt might not be the most glamorous aspect of car maintenance, but it’s undoubtedly one of the most critical. Your timing belt plays a vital role in synchronizing the rotation of the engine’s crankshaft and camshaft, ensuring that valves open and close at the right times during the engine’s operation. Ignoring its replacement can lead to costly repairs or even catastrophic engine failure.

In this guide, we’ll delve into the importance of timing belt replacement, when to replace it, and what the process entails.

What to Expect:

The timing belt is a crucial part of engines found in the engine compartment, along with the drive belts. Made of tough rubber, it’s like a conductor, making sure the crankshaft and camshaft(s) work are in sync perfectly. This teamwork is vital for keeping the engine’s timing just right. When the crankshaft turns, the timing belt makes sure the camshaft(s) open and close the engine valves at exactly the right moment.

This precise timing keeps the engine running smoothly and efficiently. Without it, the engine could get damaged, causing problems. So, even though it’s small, the timing belt plays a big role in keeping engines running smoothly.

Keep in mind:

  • When replacing a timing belt, they also replace the water pump, tensioner, and timing belt pulley.
  • If the pulleys and tensioners should fail after only replacing the belt, it can cause valve or piston damage and lead to more expensive engine repairs, in order to have the engine run properly. It is therefore essential to replace the whole set.
  • We only replace the water pump if it is driven by the timing belt (true for 60% of cars).

10 Signs That It’s Time to Replace the Timing Belt

Knowing when it’s time to replace your timing belt is crucial for maintaining the health and reliability of your vehicle’s engine. Here are ten signs that indicate it’s time for a timing belt replacement:

1. Mileage – Manufacturers typically advise changing the timing belt every 60,000 to 100,000 miles, so if your vehicle has reached or beyond this mileage, it is probably time for a replacement.

2. Age – Even if your vehicle hasn’t reached the recommended mileage interval, timing belts deteriorate over time, so consider replacing it if it’s been in use for around 5 to 7 years.

3. Visible Wear – Check the timing belt for signs of wear, such as fractures, fraying, or missing teeth. These signal that the belt is nearing the end of its life.

4. Engine Misfires – A damaged timing belt can cause engine failure or rough idling because the crankshaft and camshaft are not properly synchronized.

5. Ticking or Clicking Noises – Strange ticking or clicking noises coming from the engine may indicate a loose or damaged timing belt.

6. Oil Leaks – Oil leaks near the timing belt cover can cause the belt to deteriorate prematurely, so check for any signs of leakage.

7. Engine Vibration – A broken timing belt can create significant engine vibration, which can be sensed via the steering wheel or floorboard.

8. Difficulty Starting the Engine – If your vehicle struggles to start or takes longer than usual to crank, it could be a sign of timing belt wear.

9. Check Engine Light – A illuminated check engine light may indicate timing belt-related issues, so have the vehicle’s diagnostics checked to identify any potential problems.

10. Visible Belt Damage – If the timing belt cover is removed and you notice visible damage to the belt, such as chunks missing or severe wear, it’s time for a replacement.

By staying vigilant for these signs and addressing them promptly, you can avoid potential engine damage and ensure the continued reliability of your vehicle.

Essential Tools for Replacing a Timing Belt

When it comes to replacing a timing belt, having the right tools and materials is crucial to ensure the job is done correctly and efficiently. Here’s a breakdown of the necessary tools and materials you’ll need for the task:

  1. Timing Belt Kit – This kit typically includes the timing belt itself, as well as any additional components like tensioner pulleys, idler pulleys, and water pump. Make sure to get a kit that is specifically designed for your vehicle’s make and model.
  2. Wrenches and Socket Set – You’ll need a set of wrenches and sockets in various sizes to remove bolts and nuts from components like the timing belt cover, tensioner, and pulleys.
  3. Torque Wrench – A torque wrench is essential for tightening bolts to the manufacturer’s specifications without over-tightening, which could damage components.
  4. Screwdrivers – Both flathead and Phillips screwdrivers may be needed for removing screws or prying off components during the replacement process.
  5. Pliers – Pliers can be handy for holding bolts or clamps in place while you work, or for removing stubborn components.
  6. Timing Belt Diagram – Having a diagram of the timing belt routing specific to your vehicle is invaluable for ensuring the new belt is installed correctly. This diagram illustrates the proper placement of the belt around the various pulleys and gears in the engine.
  7. Gloves and Safety Glasses – Safety should always be a priority when working on a vehicle. Gloves can protect your hands from sharp edges and hot components, while safety glasses shield your eyes from debris and fluids.
  8. Clean Rags and Solvent – Before installing the new timing belt, it’s essential to clean any dirt, oil, or debris from the components in the timing belt area. Use clean rags and a suitable solvent to ensure a clean working environment.
  9. Service Manual or Repair Guide – While not a physical tool, having access to a service manual or repair guide specific to your vehicle can provide valuable information and guidance throughout the timing belt change process.

By gathering these tools and materials before you start the timing belt replacement, you can streamline the process and ensure a successful outcome. Remember to follow the manufacturer’s instructions and safety precautions every step of the way to avoid any mishaps or damage to your vehicle.

How It’s Done:

  • Remove accessories needed to gain access to the engine timing cover.
  • Remove the engine timing cover, inspect the timing belt and pulleys for needed parts.
  • Remove and replace the timing belt, water pump, pulleys, and tensioners.
  • Reinstall the timing cover and all removed parts.
  • Start the engine and check for proper engine operation and engine timing, as well as for cooling system leaks.


Follow the maintenance schedule provided by the manufacturer and replace the timing belt as recommended. The timing belt drives the water pump in 60% of the cars. The labor cost of replacing the water pump is significantly higher than the cost of the pump. While replacing the timing belt, it is cost-effective to replace the water pump. We highly recommend replacing the timing belt pulleys and tensioners.

The timing belt tensioner applies pressure to the timing belt, keeping it tight, while the pulleys keep the timing belt in line. These components are sealed units that contain bearings (they cannot be lubricated on a regular basis). The bearings wear out over time and may seize, causing the timing belt to come off, which can cause major internal engine damage.

Why Replacing a Timing Belt is Important

The timing belt is a rubber belt in your car’s engine that helps control when the valves open and close. As your car runs, this belt can wear down or break, especially if your car has been driven a lot. If the timing belt breaks, it can make the valves hit the pistons, which can really damage the engine. This might mean a big repair bill or even needing a whole new engine. That’s why it’s super important to get your timing belt changed regularly to keep your car running smoothly and avoid big problems down the road. If your timing belt isn’t working right, your car might show a warning light on the dashboard, so it’s essential to pay attention to it!
