Timing Belt

The timing belt controls the crank and camshafts in the engine, ensuring a smooth operation by opening and closing valves at the correct time in synchronization. The timing belt is made up of synthetic rubber which is reinforced with fiber cords and is in constant timed motion. The crankshaft converts linear energy from the pistons which move up and down while the camshaft open and close the engine's valves and because of the timing belt, these become linked in harmony. Without it, the pistons and valves would collide.

What can go wrong?

Eventually, the timing belt will begin to wear and tear but some other factors affecting its life could be from oil leaks which will corrode the belt or infrequent driving, causing the belt to become a set shape. If the timing belt breaks or jumps a notch, the valves may open at the wrong time and be struck by the pistons; causing hundreds of dollars in damage to your engine.

What can you do?

If you notice any slapping or scraping noises from the engine, or if you feel any "jumps" or "skips", it could mean there is a loss of synchronization; be sure to see a service advisor right away. Always check your owner's manual or ask a service advisor when your timing belt needs to be replaced so you can avoid any major maintenance repairs.
