Timing Belt

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, usually 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’re approaching your assistance 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 on 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 simple part for such an important function, so when it snaps, factors get a lot more complicated. Unlike many car parts that steadily 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. One 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 moves independently in an interference engine, there will be 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 or metallic shield that should be easy to remove) and examine it for drying, fraying and discoloration.
You can replace the timing belt yourself when you have access to the necessary equipment. In some cars, it’s a straightforward procedure — remove the engine covers and shrouds, fall into line the camshaft and crankshaft, slip off the outdated belt, and slip on the new one. Occasionally, though, it’s much more complicated. For instance, 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 need an engine hoist or stand to safely replace the mount
Keep in mind that one in this work, such as for example 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 correct rate. The crankshaft movements pistons up for compression and exhaust cycles, as the pistons move down for power and intake cycles. Depending on the vehicle make, a timing belt will also run the drinking water pump, 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 fully closed during compression, a lot of the engine’s power will become lost.
Many car owners may wonder how often to replace a timing belt. As technology offers improved, many manufacturers suggest intervals up to 100,000 kilometers. To be safe you should verify what the vehicle’s producer recommends and stay within that mileage. Faulty timing belt symptoms include a lack of power, lack of fuel economy, misfiring and engine vibration. Timing belt sound 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 slight chatter sound but 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 will require removing the timing belt cover and belt. Generally in most automobiles, the belt must be eliminated if the water pump must be replaced. Reinstalling a used belt is not a good idea. The belt will have stretched and obtaining the timing set exactly right is difficult. The majority of the price of belt or drinking water pump replacement is the labor. You should invest in a new belt. This rule also applies if you are replacing a timing belt. You should think about having 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 expense of the next service with a higher 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 therefore the engine’s valves and pistons move around in sync. The anticipated lifespan of your timing belt is certainly 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 probably won’t need to replace your belt any previously [source: Allen]. Nevertheless, if you’re approaching your program interval and also have doubts about the belt’s condition, you might as well get it replaced just a little early. It’ll be less costly than waiting until following the belt breaks.

It’s a straightforward part for this kind of an important function, so when it snaps, points get a lot more difficult. Unlike many car parts that steadily lose function as they wear out, a timing belt simply fails. Whether the belt breaks or a few teeth strip, the end result is the same. One minute, your car will be running flawlessly; the next minute, it will not. You’re in big trouble if your car has an “interference engine,” in which the valves are in the road of the pistons. If the camshaft or crankshaft techniques independently in an interference engine, you will see at least one valve/piston collision.

It’s easy to check the belt for indicators of premature wear — just locate it in the engine bay (usually under a plastic material or steel shield that needs to be easy to remove) and examine it for drying, fraying and discoloration.
You can replace the timing belt yourself should you have access to the required equipment. In some cars, it’s a straightforward procedure — remove the engine covers and shrouds, line up the camshaft and crankshaft, slip off the older 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 particular case the mount would need to be removed to access the belt. You’d need an engine hoist or stand to securely remove and replace the mount
Keep in mind that one in this work, such as improperly turning the engine by hand or failing woefully to coordinate the shafts, will cause the same damage because a snapped belt.

The crankshaft movements pistons up for compression and exhaust cycles, while the pistons move down for power and intake cycles. According to the vehicle make, a timing belt will also run the 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 at the correct time to allow energy to enter the chamber and close to enable compression. 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.

In most vehicles, the belt must be removed if the drinking water pump must be changed. Reinstalling a used belt is not an excellent idea.

This guideline also applies when you are changing a timing belt. You should think about getting the drinking water pump replaced simultaneously. If the pump is near the end of its expected life cycle, you will put away on the expense of the second service with a high labor cost.
