What are the Indicators of a Worn Timing Belt?

Learn the indicators of a worn timing belt at Beck & Masten GMC Coastal Bend.

A failing timing belt can show a myriad of symptoms, such as noises coming from under the hood, engine misfires, and poor engine performance. In many situations, if the timing belt breaks, the worst-case scenario is that engine will not run at all, and the engine will not restart without replacing the timing belt. On other vehicles, a timing belt failure can mean catastrophic damage. It should be noted that some cars have a timing chain instead of a timing belt, but they function in the same manner. Other signs of a bad Timing Belt (or bad timing chain) might include the Check Engine light coming on, clanking or ticking noises coming from the front of the engine, and new engine vibrations. While not as obvious as other parts like the brakes, shocks (and struts), or transmission, the timing belt (or timing chain) is a critical component that needs attention.

How Does a Timing Belt Work?

The timing belt ensures that the crankshaft and camshaft are synchronized with the engine. This synchronization of the camshaft and crankshaft is essential for the engine’s valves to function in the correct sequence, and thus, allowing the engine to work correctly. Timing belts are typically constructed using rubber and are subject to wear and tear over time. Some cars are equipped with timing chains instead of timing belts. Timing chains do the same job but are constructed of metal. Timing chains can have a longer lifespan but also need to be replaced over time.

What Is The Typical Cost of Replacing a Timing Belt?

The price of timing belt replacement can change because of several factors, like the age of the vehicle, the make and model, and the replacement costs. For example, replacing a timing belt on an older engine with a more simple engine design will likely have a lower cost than a new sports car with a complex engine design. Additionally, some cars may highly suggest that other parts be replaced while replacing the timing belt, such as the water pump, idler pulleys, and tensioners, which can increase the cost of the service.

How Long Does a Timing Belt Last?

A timing belt (or chain) should be according to the recommendations from the vehicle manufacturer, which can range from every 5-7 years or 60,000 to 100,000 miles, depending on the make and model and usage of the vehicle. Some drivers may want to replace the timing belt sooner due to the type of driving the vehicle is subjected to (such as extreme hot or cold weather, frequent short trips, or high-mileage use). Overall, it is better to replace the timing belt early to avoid costly engine damage.
