How long is it appropriate to replace the car engine belt

The timing belt of a car is responsible for the opening timing of the valves. If the valves open randomly, the engine will be scrapped directly due to the "top cylinder". Do you now know that the timing belt of a car is powerful? Once the timing belt breaks, it will be instantly scrapped, so it is necessary to regularly replace the timing belt.

The engine belt is divided into timing belt and water pump belt. There are two types of timing belts and chains. The chain is maintenance free and does not need to be taken care of during the vehicle's service life! The belt, as a rubber component, will age and needs to be replaced. The replacement mileage is generally between 50000 and 120000 yuan!

If the timing belt has reached the manufacturer's recommended replacement mileage, I personally recommend replacing it, because a broken timing belt can cause the camshaft to break and the valve to malfunction, and the repair cost is relatively expensive!

The replacement mileage of the water pump belt is generally 50000 kilometers. During this period, if there is a squeaking sound when starting or starting, it is mostly caused by insufficient tension of the water pump belt! If the aging is not severe, it can be solved by adjusting the tension and continue to be used! If the aging of the water pump belt is not severe, even if it exceeds the mileage specified by the manufacturer, it can still be used and needs to be replaced according to the situation!

The replacement mileage for different car models may vary, which can be referred to the replacement cycle provided by the manufacturer in the user manual! Very specific and detailed! As for the 4S recommendations, if they are inconsistent with the manual, it is recommended to refer to the manual for accuracy!

Below are some suggestions from the editor:

1. Normal mileage is 100000, some models are 150000. It is recommended to replace the timing belt together with the belt tensioner and two guide tensioner pulleys.

2. If you are unsure about the mileage of belt replacement for your own car, you can refer to the user manual.

3. Some reasons for belt breakage: belt tensioner bearing jamming, causing belt tension; The difficulty in rotating the engine crankshaft leads to timing deviation, oil seal leakage, and reduced lifespan caused by belt sticking oil sludge.

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 replaced according to the mileage in the user manual.

4. It is recommended to check and replace the timing belt in advance for vehicles that are frequently loaded or overloaded, such as vans and cargo trucks. Due to the high load of the vehicle, the engine wear and tear will also be greater than that of a typical grocery car.

5. Timing chains are generally recommended to be inspected and replaced according to the advice of maintenance technicians if abnormal engine noise is heard.
