Most people have probably heard of timing belts, but don’t know much about them. The timing belt is an important part of the engine distribution system, but also the key to the normal operation of the engine. It has a great impact on the intake and exhaust time, and rubber products will gradually age, at this time we should replace them in time. How long will a timing belt or chain last? With such a question, today to give you a popular science.
How long will the timing belt last?
There is no definitive answer to how long the timing belt will last because some cars are scrapped with the timing belt or chain still working. Generally according to the car maintenance manual operation on the line. In the car maintenance manual, there will be timing belt maintenance time and mileage recommendations. In general, the engine timing belt needs to be replaced once after about 60,000 kilometers of use. But in hot or cold climates, the timing belt may need to be replaced every 50, 000 kilometers. Generally, the timing belt of the original factory is more durable, and the first replacement can reach 100,000-150,000 kilometers. 4S car shops will let you replace it at 60% of the maintenance cycle. For example, if the maintenance period is 150,000 kilometers, it will tell you about 80-90,000 kilometers need to be replaced. If the mileage is not met, more than 5 years also need to check the timing belt.
Impact of timing belt break on the engine
A timing belt is a toothed belt that connects the engine crankshaft to one or more camshafts. The timing belt synchronizes the camshaft to the crankshaft position so that the valves will open and close at the appropriate timing relative to the piston position. In some engines, timing belts can also drive other components such as water pumps, balance shafts, intermediate shafts, jet pumps, and oil pumps, so timing belts are important for cars. It is different from the driving belt of the attached device. It is easy to observe that once the aging degree of the timing belt is too high, there may be a sudden fracture at any time. After a fracture, the internal valve of the engine may be damaged, and even hit the valve ejector rod and concave piston top. If the timing belt breaks, the engine will no longer work and the camshaft will stop spinning, causing serious damage to the engine. The timing belt is not a valuable part, compared with the engine is very cheap, so if you do not want to let the engine be scrapped to regularly check the use of timing belt, to prevent the occurrence of accidents.
How to check the timing belt?
If we do not grasp the timing of the belt replacement cycle, then we usually need to observe the use of the belt. The timing belt can be tested once a year after the recommended maintenance time. If the rubber surface is not delicate enough or feels very rough when touched, this situation should be noted. At this time, we can illuminate it with a flashlight to observe whether there are white traces or cracks on its surface. If the belt is fine and lubricated, don’t worry. If the surface of the belt begins to whiten, it means that the belt is gradually losing its toughness and should be replaced as soon as possible. If cracks appear, the belt is damaged and should be replaced immediately. If the timing belt has a fault, there will be some signs, such as engine weakness, abnormal sound, can not to start or start for a long time.
There are two points to pay attention to when checking. One is that the car must be hot before checking. The second is the drive belt, which is easy to see and check, unlike the accessory device. Some timing belts are hidden inside a cover and need to be removed to see.
Timing belt kit recommended
If you are replacing timing belts, it is best to have a professional engine timing tool, such as AUTOOL timing tool kit. It provides a complete suite to help you with timing. The kit contains everything you need to do your job, including the camshaft pulley lock tool, sprocket tool, guide pin, crankshaft tool. Designed for Land Rover 2.0 and 2.5 V6 engines, it is a professional tool for checking and adjusting the timing of Land Rover engines without modification.
