The symptoms of a Hyundai car timing belt going bad are detected in the timing of the engine. When engine timing is not working properly, issues arise, such as excessive exhaust fumes, shaking or jerking when gears shift and other, finer symptoms that may go unnoticed. If the timing belt does go out on a Hyundai car, the engine will quit.
The timing belt is under the hood of the Hyundai and is the band or belt which wraps around the pulleys of the engine components located in the front of the engine. The timing belt turns all of the pulleys and can be visually inspected for cracks, wear or tears in the grooves or on the outside of the belt. This visual inspection of the timing belt needs to be done along the entire length of the belt. If any damaged areas are found, the timing belt needs to be replaced as soon as possible.
Stretched Timing Belt
The timing belt stretches as a car is driven. This stretching comes from ordinary wear and can cause the timing of the engine to get out of sync. The Hyundai will begin to miss when accelerated or upon initial start-up. If the car begins to miss-out during operation, then it needs to be replaced.
Unusual Engine Noise
Another symptom of the timing belt going bad on a Hyundai car is unusual sounds coming from the engine compartment. These noises can be everything from a knocking or tapping sound to just a slightly different than normal sound. If there is any change in the sound or noise of the engine, the timing belt should be checked or replaced.
