Kia valvetrain components, like the Kia timing belt and Kia timing chain, are essential for proper engine operation. The Kia timing belt is just what it sounds like: a toothed belt. By linking the camshaft with the crankshaft, the Kia timing belt ensures exact valve timing as your engine rotates. Some Kia models may have a Kia timing chain in place of the Kia timing belt. In such cases, the Kia timing chain performs the exact same function. Most models will have a Kia timing belt, however, due to the fact that it's quieter and requires less power to operate. The Kia timing belt does have a downside, though: If it isn't replaced at the manufacturer's specified intervals, the Kia timing belt can break and cause major engine damage. Even if your engine is running fine, the Kia timing belt has to be changed according to the mileage in your owner's manual. The process isn't cheap, but you can save a lot of money by purchasing your new Kia timing belt from us and installing it yourself. The job isn't hard as long as you have a good repair manual and a premium quality Kia timing belt like the ones we carry. If you have a Kia timing chain on your vehicle, your owner's manual will make no mention of a replacement schedule. That's because the Kia timing chain is generally a 'lifetime' component and doesn't require periodic replacement. Don't be scared of a Kia timing belt job, though: As long as you follow the directions and change the Kia timing belt when you're supposed to, it's every bit as reliable as a Kia timing chain.
