How long does it take to replace the automobile engine belt? What does the engine belt do?

Replace the timing belt for 60,000-80,000 yuan.

The belt is an important part of the engine valve system, and the accuracy of intake and exhaust time is ensured by connecting with the crankshaft and matching with a certain transmission ratio. The belt is used instead of gear transmission because the belt has low noise, accurate transmission, small self-change and easy compensation.

First, the timing belt has the advantage of low noise, but the disadvantage is that it needs to be replaced on time; The advantage of timing chain is that it does not need to be replaced, but the disadvantage is that it is noisy in the later stage.

Second, the timing belt, how many kilometers need to be replaced? Engine timing belt, also known as timing belt, is an important part of engine valve train. The upper part is connected with the camshaft formal wheel of the cylinder head, and the lower part is connected with the crankshaft timing wheel. Due to the trouble of disassembly and high technology, the cost of replacing the timing belt is basically around 1000 yuan.

Third, models with synchronous belts of 60,000-90,000 km, such as Volkswagen Passat, Audi A8, Audi A6, LaVida, Sagitar, POLO, Jetta, Santana, Peugeot, Cheetah, Lexus, Lan Se, Haifuxing, Citroen (90,000 km), Regal Buick, Corolla and so on. The cost is about 800-3000 yuan. (Maintenance-free timing chain generally does not need to be replaced without abnormal sound. )

4. What if the timing belt is broken? Breaking the timing belt will cause the car to stall (note: don't start it again, so as to reduce the loss). Generally, the valve of the engine is damaged, the piston is severely deformed, the connecting rod is bent, and even the cylinder block is broken, and the maintenance cost ranges from thousands to tens of thousands. If the timing belt is used, please keep in mind the replacement cycle, and it is best to replace it in time when the mileage is reached.

When replacing the timing belt, it is recommended that the water pump, timing belt and tensioner be replaced together.

Summary: The labor cost and material cost of replacing the timing belt are generally around 1000 yuan, and the timing belt is generally around 60,000-90,000 kilometers (depending on the vehicle type). But it doesn't mean that it will break down immediately if it exceeds 60,000 kilometers. Some car owners can drive 65,438+10,000 kilometers, but the risk factor of breaking down will increase after exceeding the replacement mileage. You never know when the timing belt will suddenly break, and the consequences will only bring more trouble, especially when the highway breaks down.
