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 in sync. The expected lifespan of your timing belt is certainly specific to your car and engine configuration, usually between 60,000 and 100,000 miles.
The manufacturer’s recommended intervals are a safe guideline; you almost certainly won’t need to replace your belt any earlier [source: Allen]. Nevertheless, if you’re approaching your service interval and also have doubts about the belt’s condition, you may as well obtain it replaced a little early. It’ll be less costly than waiting until following the belt breaks.
Why is it vital that you replace the timing belt on such a strict timetable? The belt is definitely a synthetic rubber strap which has fiber strands for power. It has the teeth to avoid slipping, which fit into the grooves on the finish of the camshaft and crankshaft. It’s a simple part for such an important function, and when it snaps, stuff get a lot more complicated. 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 outcome is the same. One minute, your car will be running properly; the next minute, it will not. You’re in big trouble if your car comes with 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 will 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 material or metallic shield that needs to be simple to remove) and verify it for drying, fraying and discoloration.
You can replace the timing belt yourself if you have access to the required equipment. In a few cars, it’s an easy procedure — take away the engine covers and shrouds, fall into line 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 need an engine hoist or stand to safely remove and replace the mount
Keep in mind that one in this job, such as for example improperly turning the engine yourself 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. With respect to the automobile make, a timing belt will also run the 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 correct 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 escape through an open up exhaust valve. If the valves aren’t fully closed during compression, a lot of the engine’s power will be lost.
Many car owners may wonder how often to displace a timing belt. As technology has improved, many manufacturers suggest intervals up to 100,000 miles. To be safe you should check 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 sound is no longer probably the most obvious indicators of potential belt failure. When the vehicles experienced 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 moderate chatter sound but absolutely nothing compared to the sounds 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 removing the timing belt cover and belt. Generally in most vehicles, the belt must be eliminated if the drinking water pump must be replaced. Reinstalling a used belt is not a good idea. The belt could 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 invest in a new belt. This rule also applies if you are replacing a timing belt. You should think about getting the drinking water pump replaced at the same time. If the pump can be near the end of its expected life cycle, you will put away on the expense of the second service with a higher labor cost.

Why is it vital that you replace the timing belt on such a strict schedule? The belt is a synthetic rubber strap which has fiber strands for power. It has teeth to prevent slipping, which fit into the grooves on the finish of the camshaft and crankshaft. It’s a straightforward part for this kind of an important function, so when it snaps, factors get a lot more difficult. Unlike many car parts that steadily lose function as they degrade, a timing belt basically fails. If the belt breaks or a few teeth strip, the outcome is the same. About a minute, your vehicle will be running flawlessly; the next minute, it won’t. You’re in trouble if your car comes with an “interference engine,” where the valves are in the road of the pistons. If the camshaft or crankshaft movements independently within an interference engine, you will have at least one valve/piston collision.

Keep in mind that an error in this work, such as improperly turning the engine by hand or failing to coordinate the shafts, may cause the same damage as 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 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 up at the correct time to allow gasoline 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 aren’t fully closed during compression, the majority of the engine’s power will be lost.

This rule also applies when you are changing a timing belt. You should consider getting the drinking water pump replaced simultaneously. If the pump is near the end of its expected life cycle, you will save on the price of the next service with a higher labor cost.
