Your car’s timing belt is accountable 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 can be specific to your vehicle and engine configuration, usually 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 previously [source: Allen]. However, if you’re approaching your provider interval and have doubts about the belt’s condition, you might as well get 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 on such a strict schedule? The belt is definitely a synthetic rubber strap which has fiber strands for power. 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, items get much more difficult. Unlike many car parts that gradually lose work as they degrade, a timing belt just fails. If the belt breaks or a few teeth strip, the end result is the same. One minute, your vehicle will be running perfectly; 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 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 an expensive repair.
It’s easy to examine the belt for signals of premature wear — just locate it in the engine bay (usually under a plastic-type material or metal shield that should be easy to remove) and check it for drying, fraying and discoloration.
You can replace the timing belt yourself in case you have access to the necessary 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 slip on the new one. Occasionally, though, it’s a lot 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 access the belt. You’d require an engine hoist or stand to properly replace the mount
Keep in mind that an error in this job, such as improperly turning the engine by hand or failing woefully to coordinate the shafts, will cause the same damage as 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. Based on the vehicle make, a timing belt will 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 correct time to allow fuel 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. If the valves are not completely closed during compression, a lot 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 safe 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 one of the most obvious indicators of potential belt failure. When the vehicles got timing chains they might become very noisy because they loosened and started to chatter. Now that vehicle manufacturers are using belts you are less inclined to hear when it turns into loose or cracks. Belts can create a gentle chatter sound but nothing compared to the seems 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 the removal of the timing belt cover and belt. Generally in most automobiles, the belt must be eliminated if the water pump must be changed. 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 water pump replacement is the labor. You should invest in a new belt. This guideline also applies when you are changing a timing belt. You should think about getting the water pump replaced simultaneously. If the pump is definitely near the end of its anticipated life cycle, you will put away on the price of the second service with a high labor cost.

Why is it important to replace the timing belt upon 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 finish of the camshaft and crankshaft. It’s a straightforward part for such an important function, and when it snaps, stuff get much more difficult. Unlike many car parts that steadily lose work as they degrade, a timing belt basically 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 comes with an “interference engine,” in which the valves are in the path of the pistons. If the camshaft or crankshaft moves independently within an interference engine, you will see at least one valve/piston collision.

You can replace the timing belt yourself should you have access to the necessary equipment. In some cars, it’s an easy procedure — remove the engine covers and shrouds, fall into line the camshaft and crankshaft, slip off the older belt, and wear the new one. Sometimes, though, it’s much more complicated. For instance, the timing belt might loop through a engine mount, in which case the mount would have to be removed to access the belt. You’d require an engine hoist or stand to safely remove and replace the mount

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. With respect to the vehicle make, a timing belt will also run the 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 correct time to allow fuel to enter the chamber and close to enable compression. If the timing routine 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 end up being lost.

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 inclined to hear when it turns into loose or cracks. Belts can create a moderate chatter sound but absolutely nothing in comparison to the noises of a timing chain.
You can also answer 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. In most vehicles, the belt should be taken out if the water pump must be replaced. Reinstalling a used belt is not an excellent idea. The belt will have stretched and obtaining the timing set precisely right is difficult. Nearly all the cost of belt or water pump replacement may be the labor. You should choose new belt. This guideline also applies when you are replacing a timing belt. You should consider having the water pump replaced simultaneously. If the pump is near the end of its expected life cycle, you will save on the expense of the second service with a high labor cost.
