Why Timing Belt Maintenance Can Save Your Engine

Posted in Warranty on June 14, 2026

One part of your vehicle you probably never think of is the timing belt. It coordinates the rotation of the crankshaft (which converts the up and down motion of the pistons into rotation motion) and the camshaft (which opens and closes your engine’s valves). It’s vital that the timing of these movements happens precisely when it needs to so your engine will operate smoothly and perform the way it’s designed to. It also prevents damage to the engine.

If your engine’s timing belt breaks, it can leave you stranded, plus cause costly, catastrophic damage to the engine. Depending on your vehicle, a failed timing belt can wind up causing a collision between the pistons and the valves, and it’s possible it can destroy the cylinder head. Repairs can be extremely expensive and, in some cases, your engine might not even be repairable. And that is why maintaining your timing belt is extremely important.

Your vehicle’s manufacturer provides recommendations on when your timing belt should be replaced, often between 60,000-100,000 miles/95,000-160,000 km, or about every 5 to 7 years. Depending on how you drive and in what conditions (such as extreme temperatures), your engine may need its timing belt checked more frequently. The longer and harder your belt works, the more likely it will get brittle and crack. When your vehicle is in for a timing belt replacement, your service manager will frequently recommend replacing other components as well, such as water pumps, pulleys and tensioners.

Regular timing belt maintenance will help you maintain your vehicle’s performance and may allow you to avoid expensive repairs later.
