Your car’s timing belt is responsible for maintaining the precision that’s crucial 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 expected lifespan of your timing belt is certainly 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 replace your belt any previously [source: Allen]. However, if you are approaching your support interval and also have doubts about the belt’s condition, you may as well get it replaced just a little early. It’ll be less expensive than waiting until after the belt breaks.
Why is it important to replace the timing belt on such a strict plan? The belt is usually a synthetic rubber strap that contains fiber strands for power. It has tooth to avoid slipping, which fit into the grooves on the end of the camshaft and crankshaft. It’s a simple part for such an important function, so when it snaps, things get a lot more difficult. Unlike many car parts that steadily lose function as they wear out, a timing belt basically fails. If the belt breaks or a few teeth strip, the end result is the same. One minute, your car will be running perfectly; the next minute, it won’t. You’re in trouble if your car has an “interference engine,” in which the valves are in the road of the pistons. If the camshaft or crankshaft moves independently in an interference engine, you will see at least one valve/piston collision. The fragile valves will bend, and you’ll be faced with a costly repair.
It’s easy to check the belt for indications of premature wear — just locate it in the engine bay (usually under a plastic-type or steel shield that should be easy to remove) and examine it for drying, fraying and discoloration.
You can replace the timing belt yourself in case you have Timing Belt china access to the necessary equipment. In some cars, it’s an easy procedure — remove the engine covers and shrouds, line up the camshaft and crankshaft, slip off the old belt, and slip on the new one. Occasionally, though, it’s much more complicated. For instance, the timing belt might loop through a engine mount, in which particular case the mount would need to be removed to gain access to the belt. You’d need an engine hoist or stand to securely remove and replace the mount
Keep in mind that an error in this job, such as improperly turning the engine yourself or failing woefully to coordinate the shafts, may cause the same damage since 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, while the pistons move down for power and intake cycles. Based on the automobile make, a timing belt may also run the drinking water pump, oil pump and injection pump. The camshaft controls the starting and closing of the valves for intake and exhaust. The valves must open up at the right time to allow energy to enter the chamber and then close to allow for compression. If the timing cycle is off, fuel might not enter the cylinder or could get away through an open up exhaust valve. If the valves aren’t completely closed during compression, the majority of the engine’s power will be lost.
Many car owners may wonder how often to replace a timing belt. As technology provides improved, many manufacturers recommend intervals up to 100,000 miles. To be safe you should examine what the vehicle’s producer recommends and stay within that mileage. Faulty timing belt symptoms include a lack of power, loss of fuel economy, misfiring and engine vibration. Timing belt sound is no longer probably the most apparent indicators of potential belt failing. When the vehicles got timing chains they would become very noisy because they loosened and started to chatter. Given that vehicle manufacturers are employing belts you are less likely to hear when it becomes loose or cracks. Belts can create a slight chatter sound 
but nothing in comparison to the seems of a timing chain.
You can also answer the question of when to displace a timing belt if you are having other work done that requires removing the timing belt cover and belt. Generally in most automobiles, the belt must be taken out if the drinking water pump must be replaced. Reinstalling a utilized belt is not a good idea. The belt will have stretched and getting the timing set precisely right is difficult. The majority of the expense of belt or water pump replacement is the labor. You should invest in a new belt. This rule also applies when you are changing a timing belt. You should consider getting the water pump replaced at the same time. If the pump is usually near the end of its anticipated life cycle, you will put away on the expense of the next service with a higher labor cost.
Your car’s timing belt is accountable for maintaining the precision that’s essential to your engine’s functions. Essentially, it coordinates the rotations of the camshaft and crankshaft therefore the engine’s valves and pistons move in sync. The expected lifespan of your timing belt is definitely specific to your vehicle and engine configuration, generally between 60,000 and 100,000 miles.
The manufacturer’s recommended intervals certainly are a safe guideline; you almost certainly won’t need to replace your belt any previously [source: Allen]. However, if you’re approaching your program interval and also have doubts about the belt’s condition, you might as well obtain it replaced just a little early. It’ll be less expensive than waiting until after the belt breaks.
Why is it vital that you replace the timing belt upon such a strict plan? The belt is definitely a synthetic rubber strap which has fiber strands for strength. It has tooth to avoid slipping, which match the grooves on the finish of the camshaft and crankshaft. It’s a straightforward part for this kind of an important function, and when it snaps, factors get much more difficult. Unlike many car parts that gradually lose function as they wear out, a timing belt merely fails. Whether the belt breaks or a couple of teeth strip, the end result is the same. One minute, your vehicle will be running perfectly; the next minute, it won’t. You’re in trouble if your car has an “interference engine,” where the valves are in the road of the pistons. If the camshaft or crankshaft moves independently in an interference engine, you will have at least one valve/piston collision. The fragile valves will bend, and you’ll be faced with a costly repair.

Sometimes, though, it’s much more complicated. For instance, the timing belt might loop through a electric motor mount, in which case the mount would need to be removed to access the belt. You’d need an engine hoist or stand to safely remove and replace the mount
Keep in mind 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. Depending on the automobile make, a timing belt may also run the water pump, essential oil pump and injection pump. The camshaft controls the opening and closing of the valves for intake and exhaust. The valves must open at the correct time to allow energy to enter the chamber and then close to allow for compression. If the timing routine is off, fuel may not enter the cylinder or could get away through an open exhaust valve. If the valves are not fully closed during compression, the majority of the engine’s power will end up being lost.
Many car owners may wonder how often to replace a timing belt. As technology has improved, many manufacturers suggest intervals up to 100,000 kilometers. To be safe you should examine what the vehicle’s producer recommends and stay within that mileage. Faulty timing belt medical indications include a lack of power, loss of fuel economy, misfiring and engine vibration. Timing belt noise is no longer one of the most apparent indicators of potential belt failure. When the vehicles had timing chains they would become very noisy because they loosened and began to chatter. Now that vehicle manufacturers are using belts you are less likely to hear when it becomes loose or cracks. Belts can create a mild chatter sound but absolutely nothing in comparison to the noises of a timing chain.
You can also answer fully the question of when to replace a timing belt if you are having other work done that will require the removal of the timing belt cover and belt. In most vehicles, the belt should be removed if the water pump must be replaced. Reinstalling a used belt is not an excellent idea. The belt could have stretched and obtaining the timing set precisely right is difficult. Nearly all the price of belt or drinking water pump replacement is the labor. You should choose new belt. This rule also applies when you are replacing a timing belt. You should think about having the drinking water pump replaced simultaneously. If the pump can be close to the end of its anticipated life cycle, you will save on the price of the second service with a higher labor cost.
