Your car’s timing belt is responsible for maintaining the precision that’s imperative to your engine’s functions. Essentially, it coordinates the rotations of the camshaft and crankshaft so the engine’s valves and pistons move around in sync. The anticipated lifespan of your timing belt is definitely specific to your car and engine configuration, generally between 60,000 and 100,000 miles.
The manufacturer’s recommended intervals are a safe guideline; you probably won’t need to substitute your belt any earlier [source: Allen]. However, if you’re approaching your service 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 costly than waiting until after the belt breaks.
Why is it vital that you replace the timing belt on such a strict timetable? The belt is a synthetic rubber strap that contains fiber strands for strength. It has teeth to avoid slipping, which fit into the grooves on the end of the camshaft and crankshaft. It’s a straightforward part for such an important function, so when it snaps, factors get much more difficult. Unlike many car parts that gradually lose function as they degrade, a timing belt basically fails. If the belt breaks or a couple of teeth strip, the outcome is the same. One minute, your vehicle will be running flawlessly; the next minute, it will not. You’re in big trouble if your car has an “interference engine,” where the valves are in the path of the pistons. If the camshaft or crankshaft techniques 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 signs of premature wear — simply locate it in the engine bay (usually under a plastic material or steel shield that Timing Belt china should be easy to remove) and examine it for drying, fraying and discoloration.
You can replace the timing belt yourself in case you have access to the required equipment. In some cars, it’s an easy procedure — take away the engine covers and shrouds, line up the camshaft and crankshaft, slip off the aged belt, and wear the new one. Sometimes, though, it’s a lot 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 require an engine hoist or stand to securely replace the mount
Keep in mind that an error in this job, such as improperly turning the engine by hand or failing to coordinate the shafts, may cause the same damage because a snapped belt.
The timing belt keeps the camshaft and crankshaft turning at the correct rate. The crankshaft moves pistons up for compression and exhaust cycles, as the pistons move down for power and intake cycles. According to the vehicle make, a timing belt will also run the drinking water pump, oil pump and injection pump. The camshaft handles the opening and closing of the valves for intake and exhaust. The valves must open at the right time to allow gasoline to enter the chamber and close to allow for compression. If the timing cycle is off, fuel may 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 be lost.
Many car owners may wonder how often to displace a timing belt. As technology offers improved, many manufacturers suggest intervals up to 100,000 kilometers. 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 economy, misfiring and engine vibration. Timing belt noise is no longer probably the most visible indicators of potential belt failing. When the vehicles got timing chains they would become very noisy as they loosened and began to chatter. Given that vehicle manufacturers are employing belts you are less inclined to hear when it turns into loose or cracks. Belts can create a slight chatter sound but absolutely nothing compared to the sounds of a timing chain.
You can also answer the question of when to displace a timing belt in case you are having other work done that requires removing the timing belt cover and belt. In most vehicles, the belt should be eliminated if the drinking water pump must be replaced. Reinstalling a utilized belt is not an excellent idea. The belt could have stretched and obtaining the timing set precisely right is difficult. Nearly all the expense of belt or water pump replacement may be the labor. You should invest in a new belt. This rule also applies when you are replacing a timing belt. You should think about getting the water pump replaced at the same time. If the pump is close to the end of its anticipated life cycle, you will save on the cost of the next service with a high labor cost.
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 around in sync. The expected lifespan of your timing belt is specific to your vehicle and engine configuration, usually between 60,000 and 100,000 miles.
The manufacturer’s recommended intervals certainly are a safe guideline; you almost certainly won’t need to substitute your belt any earlier [source: Allen]. Nevertheless, if you are approaching your provider interval and also have doubts about the belt’s condition, you might as well obtain it replaced a little early. It’ll be less costly than waiting until following the belt breaks.
Why is it important to replace the timing belt upon such a strict timetable? The belt is usually a synthetic rubber strap which has fiber strands for power. It has teeth to prevent slipping, which match the grooves on the end of the camshaft and crankshaft. It’s a straightforward part for this kind of an important function, and when it snaps, points get a lot more complicated. Unlike many car parts that gradually lose function as they wear out, a timing belt merely fails. Whether the belt breaks or a few teeth strip, the end result is the same. About a minute, your car will be running properly; the next minute, it won’t. You’re in trouble if your car has an “interference engine,” in which the valves are in the path of the pistons.

You can replace the timing belt yourself when you have access to the required equipment.

Occasionally, though, it’s a lot more complicated. For example, the timing belt might loop through a electric motor mount, in which particular case the mount would need to be removed to access the belt. You’d need an engine hoist or stand to properly remove and replace the mount
Remember that one in this work, such as improperly turning the engine yourself or failing to coordinate the shafts, will cause the same damage since a snapped belt.
The timing belt keeps the camshaft and crankshaft turning at the correct rate. The crankshaft techniques pistons up for compression and exhaust cycles, while 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 handles the opening and closing of the valves for intake and exhaust. The valves must open up at the correct time to allow gasoline to enter the chamber and then close to allow for compression. If the timing cycle is off, fuel may not enter the cylinder or could get away through an open exhaust valve.

To be safe you should examine what the vehicle’s producer recommends and stay within that mileage. Faulty timing belt medical indications include a loss of power, lack of fuel economy, misfiring and engine vibration. Timing belt sound is no longer one of the most visible indicators of potential belt failing. When the vehicles had timing chains they might become very noisy as 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 nothing compared to the sounds 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 requires the removal of the timing belt cover and belt. Generally in most vehicles, the belt should be eliminated if the water pump must be replaced. Reinstalling a utilized belt is not a good idea. The belt will have stretched and obtaining the timing set specifically right is difficult. The majority of the price of belt or water pump replacement may be the labor. You should 
invest in a new belt. This guideline also applies when you are replacing a timing belt. You should consider having the water pump replaced at the same time. If the pump can be near the end of its expected life cycle, you will save on the price of the next service with a high labor cost.
