Timing Belt

Your car’s timing belt is accountable 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 expected lifespan of your timing belt is usually 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 almost certainly won’t need to replace your belt any earlier [source: Allen]. However, if you are approaching your assistance interval and 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 after the belt breaks.
Why is it important to replace the timing belt upon such a strict schedule? The belt is a synthetic rubber strap which has fiber strands for strength. It has the teeth to avoid 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, so when it snaps, stuff get a lot more difficult. Unlike many car parts that gradually lose work as they degrade, a timing belt simply fails. If the belt breaks or a few teeth strip, the end result is the same. About a minute, your vehicle will be running perfectly; the next minute, it won’t. You’re in big 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 within an interference engine, you will see at least one valve/piston collision. The fragile valves will bend, and you’ll be faced with an expensive repair.
It’s easy to check the belt for symptoms of premature wear — simply locate it in the engine bay (usually under a plastic material or steel shield that should be simple to remove) and check 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 — remove the engine covers and shrouds, line up the camshaft and crankshaft, slip off the older belt, and wear the new one. Sometimes, though, it’s much more complicated. For example, the timing belt might loop through a engine mount, in which particular case the mount would have to be removed to access the belt. You’d need an engine hoist or stand to safely remove and replace the mount
Remember that one in this work, such as improperly turning the engine by hand or failing 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 movements pistons up for compression and exhaust cycles, while the pistons move down for power and intake cycles. According to the automobile make, a timing belt may also run the water pump, oil pump and injection pump. The camshaft regulates the opening and closing of the valves for intake and exhaust. The valves must open up at the right time to allow gasoline to enter the chamber and close to allow for compression. If the timing cycle is off, fuel might not enter the cylinder or could escape through an open 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 provides improved, many manufacturers recommend intervals up to 100,000 kilometers. To be secure 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 economic climate, misfiring and engine vibration. Timing belt noise is no longer one of the most noticeable indicators of potential belt failing. When the vehicles experienced timing chains they might become very noisy as they loosened and started to chatter. Given that vehicle manufacturers are employing belts you are less inclined to hear when it becomes loose or cracks. Belts can create a moderate chatter sound but absolutely nothing compared to the noises of a timing chain.
You can also answer the question of when to replace a timing belt in case you are having other work done that will require the removal of the timing belt cover and belt. Generally 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 will have stretched and getting the timing set exactly right is difficult. The majority of the expense of belt or water pump replacement is the labor. You should choose new belt. This rule also applies when you are replacing a timing belt. You should look at having the drinking water pump replaced simultaneously. If the pump is definitely near the end of its anticipated life cycle, you will save on the cost of the next service with a higher labor cost.

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 have to be removed to gain access to the belt. You’d require an engine hoist or stand to properly remove and replace the mount
Remember that an error in this job, such as improperly turning the engine by hand or failing woefully to coordinate the shafts, may cause the same damage as a snapped belt.

According to the vehicle make, a timing belt will also run the drinking water pump, oil pump and injection pump. The camshaft settings the opening and closing of the valves for intake and exhaust. The valves must open at the right time to allow fuel to enter the chamber and then close to enable 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 are not completely closed during compression, a lot of the engine’s power will end up being lost.
