The timing belt is an important part of the car, even though many road users have no idea what it is and what it does. It regulates the crankshaft and camshaft timing, which helps the engine run as efficiently as possible. Consequently, it is subjected to a great deal of stress every day.
For this reason, car owners should regularly replace the timing belt. Unfortunately, because timing belts are no longer a typical issue, they are frequently disregarded. This is due to the fact that not all cars have timing belts. Instead, several modern cars employ a chain system that doesn’t break easily and doesn’t need to be replaced often.
How it works
The timing belt is often made of rubber and high-tensile fibers. The synchronization of the crankshaft and camshaft rotation is a vital function of this component. The engine’s valves open and close at the appropriate times during each cylinder’s intake or exhaust strokes due to synchronization. A timing belt is essential for preventing pistons from striking valves, a problem that could seriously damage engines and necessitate costly repairs.
Implications of a broken timing belt
The engines of older cars had free-running or non-interference engines, in which the valves and pistons never shared a cylinder. Because modern engines are interference engines, pistons may produce more compression, which increases engine power and efficiency.
On the other hand, if the timing belt breaks, the pistons may rise and hit the open valves, severely damaging internal engine components. Because it is costly to fix, people may decide to purchase a new engine or vehicle rather than having the damaged one repaired.
This is avoided by the crankshaft and camshafts being in synchronization, however, a damaged timing belt may result in decreased engine output and ultimately engine shutdown.
A broken timing belt
Timing belt failure is typically not indicated by any symptoms. Small indicators, such as a ticking sound that could be coming from the engine, might occasionally be present. These symptoms, however, are difficult to accurately diagnose and are easy to overlook.
Frequently, a timing belt will just abruptly snap. Because of this, you must change your timing belt as soon as your owner’s handbook advises. Otherwise, you are taking a terrible risk.
Cost effects of a broken timing belt
Although the timing belt is a cheap, basic rubber belt, replacing it can cost a lot. A large portion of the engine must be disassembled to examine seals, pulleys, tensioners, and other components. The engine must then be properly timed, tested, and put back together.
This is a time-consuming technique that calls for extraordinary talent. Although replacing a timing belt is one of the more costly repairs an automobile may require, it is still less expensive than rebuilding an engine. The cost must therefore be taken into account before choosing.
When should a timing belt be replaced?
The majority of automakers mark the cost of replacing a timing belt. indicating the optimal replacement interval. The information provided typically covers a range, which is frequently represented by a mileage range of 60,000 to 100,000 miles. It’s crucial to understand that these suggestions could vary depending on the model of the car.
