Your car’s timing belt is responsible for maintaining the precision that’s essential to your engine’s functions. Essentially, it coordinates the rotations of the camshaft and crankshaft so the engine’s valves and pistons move in sync. The anticipated lifespan of your timing belt can be specific to your car and engine configuration, generally between 60,000 and 100,000 miles.
The manufacturer’s recommended intervals certainly are a safe guideline; you probably won’t need to substitute your belt any earlier [source: Allen]. Nevertheless, if you are approaching your services interval and have doubts about the belt’s condition, you might as well get it replaced a little early. It’ll be less expensive than waiting until following the belt breaks.
Why is it important to replace the timing belt upon such a strict timetable? The belt can be a synthetic rubber strap which has fiber strands for strength. It has teeth to avoid slipping, which match the grooves on the finish of the camshaft and crankshaft. It’s a simple part for such an important function, so when it snaps, stuff get a lot more difficult. Unlike many car parts that gradually lose work as they degrade, a 
timing belt just fails. Whether the belt breaks or a couple of teeth strip, the end result is the same. About a minute, your car will be running perfectly; the next minute, it won’t. You’re in big trouble if your car has an “interference engine,” in which the valves are in the path of the pistons. If the camshaft or crankshaft techniques independently within an interference engine, you will see at least one valve/piston collision. The fragile valves will bend, and you will be faced with a costly repair.
It’s easy to verify the belt for symptoms of premature wear — just locate it in the engine bay (usually under a plastic material or steel shield that should be easy to remove) and verify it for drying, fraying and discoloration.
You can replace the timing belt yourself should you have access to the necessary equipment. In a few cars, it’s a straightforward procedure — remove the engine covers and shrouds, fall into line the camshaft and crankshaft, slip off the previous belt, and wear the new one. Occasionally, though, it’s a lot more complicated. For example, the timing belt might loop through a motor mount, in which case the mount would have to be removed to access the belt. You’d require an engine hoist or stand to securely replace the mount
Remember that an error in this work, such as improperly turning the engine yourself or failing woefully to coordinate the shafts, will cause the same damage because a snapped belt.
The timing belt keeps the camshaft and crankshaft turning at the right rate. The crankshaft moves pistons up for compression and exhaust cycles, as the pistons move down for power and intake cycles. With respect to the vehicle make, a timing belt will also run the drinking water pump, essential oil pump and injection pump. The camshaft settings the starting and closing of the valves for intake and exhaust. The valves must open at the correct time to allow fuel to enter the chamber and close to enable compression. If the timing routine is off, fuel might not enter the cylinder or could get away through an open exhaust valve. If the valves are not completely closed during compression, the majority of the engine’s power will become lost.
Many car owners may wonder how often to replace a timing belt. As technology provides improved, many manufacturers suggest intervals up to 100,000 kilometers. To be secure you should check what the vehicle’s manufacturer recommends and stay within that mileage. Faulty timing belt symptoms include a loss of power, lack of fuel economic climate, misfiring and engine vibration. Timing belt noise is no longer probably the most visible indicators of potential belt failing. When the vehicles acquired timing chains they might become very noisy because they loosened and began to chatter. Now that vehicle manufacturers are employing belts you are less likely to hear when it becomes loose or cracks. Belts can create a gentle chatter sound but nothing compared to the sounds of a timing chain.
You can also answer fully the question of when to replace a timing belt in case you are having other work done that will require removing the timing belt cover and belt. In most automobiles, the belt must be taken out if the water pump must be replaced. Reinstalling a used belt is not a good idea. The belt could have stretched and obtaining the timing set exactly right is difficult. The majority of the cost of belt or drinking water pump replacement may be the labor. You should invest in a new belt. This rule also applies if you are replacing a timing belt. You should think about getting the water pump replaced simultaneously. If the pump is certainly close to the end of its anticipated life cycle, you will put away on the price of the next service with a higher labor cost.

Based on the vehicle make, a timing belt will also run the water pump, oil pump and injection pump. The camshaft regulates the starting and closing of the valves for intake and exhaust.

If the timing cycle is off, fuel may not enter the cylinder or could get away through an open up exhaust valve. If the valves aren’t fully closed during compression, the majority of the engine’s power will become lost.
Many car owners may wonder how often to displace a timing belt. As technology has improved, many manufacturers suggest intervals up to 100,000 miles. To be secure you should verify what the vehicle’s manufacturer recommends and stay within that mileage. Faulty timing belt symptoms include a loss of power, loss of fuel economic climate, misfiring and engine vibration. Timing belt noise is no longer one of the most apparent indicators of potential belt failing. When the vehicles had timing chains they would become very noisy as they loosened and began to chatter. Given that vehicle manufacturers are using belts you are less inclined to hear when it becomes loose or cracks. Belts can create a gentle chatter sound but absolutely nothing in comparison to the seems of a timing chain.

This guideline also applies if you are replacing a timing belt. You should think about having the drinking water pump replaced simultaneously. If the pump is near the end of its anticipated life cycle, you will save on the expense of the next service with a high labor cost.
