When Should Timing Belts Be Replaced? - AAA Club Alliance

Your vehicle's timing belt is responsible for keeping precision components within your engine, like the valves and camshafts, moving in a synchronized manner while also transferring power from the spinning motor to things like the water, oil, and injection pumps, in some vehicles.

What is a timing belt?

This oft unspoken hero of your vehicle’s operation usually consists of a rugged, rubber belt that includes teeth which lock onto the engine's crankshaft and camshaft. As the crankshaft is rotated by the combustion in the engine to generate power, the belt also locks onto the camshafts, which are responsible for opening and closing the engine’s intake and exhaust valves. The timing belt keeps fuel burning efficiently by "timing"—or synchronizing—all the combustion processes perfectly so your engine can breathe. It also keeps sensitive and delicate engine components from crashing into one another, which can cause catastrophic and, in some cases, irreparable damage.

Timing belt replacement

Over time, as with any rubber belt on your vehicle, the timing belt will need to be replaced. Most auto manufacturers will have a recommended replacement interval somewhere between 60,000 and 100,000 miles. This will vary from vehicle to vehicle, and you should always consult your owner's manual for the recommended replacement interval. If you suspect your timing belt needs attention, visit your local, trusted mechanic.

While timing belt replacement cost may be a major reason many drivers put off servicing their belts, failure to address timing belt wear and tear in time could result in a broken belt, an immobile vehicle, and thousands of dollars in repairs. Not only will a broken timing belt prevent your engine from running, when the delicate components it is responsible for fall out of synch, they can crash into one another—causing catastrophic damage in the form of bent valves, broken cylinders, or other expensive damage.

Timing belt repair is not something you should ever procrastinate on or deviate from the manufacturer's suggested intervals for repair. As costly as timing belt service may be, it’s a far cry from the cost of replacing your entire engine. Running your timing belt past the service interval means you’re running the risk of being on the hook for thousands of dollars in repairs or maybe even a total engine replacement.

When it’s time to replace your timing belt, there are other indicators besides the manufacturer’s interval that may let you know your timing belt needs service:

When it comes to vehicle maintenance, replacing the timing belt is one of the most critical services to keep your engine running smoothly. This essential component coordinates the rotation of the crankshaft and camshaft, ensuring your engine’s valves open and close at the right time. Neglecting to replace a worn timing belt can result in catastrophic engine damage, costing thousands in repairs.

Why Timing Belt Replacement Is Crucial

Timing belts are made of reinforced rubber, but over time, they wear down due to heat, tension, and mileage. A snapped timing belt can lead to severe damage, especially in interference engines, where the pistons and valves occupy the same space. If the belt breaks, these parts collide, often resulting in bent valves, damaged pistons, and a ruined engine.

Replacing your timing belt at the manufacturer-recommended interval (typically every 60,000 to 100,000 miles) can save you from costly repairs and keep your car running reliably.

Brands That Still Use Timing Belts

While many modern vehicles have switched to timing chains, several brands still use timing belts in their engines. Knowing if your vehicle has a timing belt can help you plan for maintenance. Here are a few brands and models that still utilize timing belts:

• Honda: Models like the Honda Accord (V6 engines), Odyssey, and Pilot still rely on timing belts.
• Subaru: Some older Subaru models, such as the Forester and Outback, have timing belts.
• Volkswagen: Select VW models, including certain Passat and Golf variants, use timing belts.
• Mitsubishi: Many Mitsubishi vehicles, like the Outlander, continue to use timing belts.
• Acura: Luxury models, including the Acura MDX and TLX, often feature timing belts.

It’s essential to check your vehicle’s owner’s manual or consult a trusted mechanic to determine if your car has a timing belt and when it needs to be replaced.

How to Know It’s Time for a Timing Belt Replacement

Pay attention to these signs, which might indicate your timing belt is due for a replacement:

• Ticking noises coming from the engine
• Engine running rough, or  trouble starting
• Oil leaking near the timing belt cover
• Visible wear, cracks, or fraying on the belt (during inspection) most are not visible without removing the cover.

If you notice any of these symptoms, don’t delay—visit a qualified auto repair shop immediately.
