Your Timing Belt & Preventing Engine Damage

Your Timing Belt & Preventing Engine Damage

Let’s address a maintenance item for preventing your vehicle from suffering severe engine damage – timing belt replacement.

Your timing belt, though seeming so insignificant, choreographs the timing of your combustion process. Meaning, it is what controls your pistons and when they travel up and down in the cylinder. Also, making sure the intake valves open at the right time to let in air and fuel, and that they close at the right time to allow the fuel to burn and then the exhaust valves open at the right time to let out the exhaust.

All this happens thousands of times a minute and it’s your timing belt that makes sure the valves are opening and closing at precisely the right time. If the timing is off, your vehicle engine won’t run. And that’s the best case.

The worst case for any driver is that a valve is opening at the wrong time and collides with the piston. The result is bent valves and maybe even more damage to the cylinder head. Repairs can run several thousand dollars.

Now, timing belts just wear out naturally so you want to replace a worn belt before it slips or breaks. Check your owner’s manual or with your friendly and knowledgeable pros at Ryan’s Servicenter to see when they recommend you replace the timing belt. If you’ve never replaced your timing belt and have had your vehicle for a while, talk with your service advisor right away to see if you’re due.

On some engines, the water pump is driven by the timing belt as opposed to the serpentine belt. If that’s the case, it’s a good idea to replace the water pump when you’re replacing the timing belt, and vice versa since much of the same work has to be done for either. The same is true for the timing belt tensioner – it should be inspected and possibly replaced.

Now, replacing a timing belt is one of the more expensive routine maintenance items on service schedules. But not replacing your timing belt can lead to some of the most repairs you’re likely to ever have.
