There are three types of belts on a car:
1. Timing belt, which is used in general gasoline vehicles
2. The fan belt, on the trolley, because the fan rotates automatically, it is not called a fan belt, but a generator belt.
3. For generators, water pumps, power steering pumps, air conditioning belts, etc., use one to three left and right angle belts. Timing belts have been used in engines for a long time, with mature technology, lower cost and less noise, but require regular inspection and maintenance. Timing chains have significant advantages such as compact structure, high transmission power, high reliability and wear resistance, and lifetime maintenance-free. However, compared with traditional timing belts, their noise is generally slightly larger.
Here are some suggestions for belt replacement
1. The normal number of kilometers for belt replacement is 100,000 kilometers, and some models are 150,000 kilometers. Replacing the timing belt It is recommended to replace the belt tensioner and both guide tensioners together.
2. If you don't know the mileage of your own car's belt replacement, you can look at the user manual.
3. Some reasons for belt breakage: The belt tensioner bearing is stuck, causing the belt to pull; the crankshaft of the engine is difficult to rotate, causing the timing to move, the oil seal leaks, and the belt sticks to the sludge and reduces the service life. under normal maintenance conditions. The engine does not leak oil, the water temperature is not high, and there is no abnormal noise. The timing belt can be completely replaced according to the mileage of the owner's manual.
4. It is recommended to check and replace the timing belt in advance for vehicles that are often full and heavy, such as vans and trucks. Because the vehicle load is large, the engine loss will also be larger than that of the general grocery shopping cart.
Is the belt by age or by kilometers?
It is recommended to change the belt first. If the number of kilometers is up and the age has not yet arrived, it can be replaced, or if the number of kilometers has not been reached, but the belt is also aging, it is recommended to replace it.
