How long does it take to change a car engine belt?

   Ordinary vehicles need to be replaced when the car engine belt has been used for one and a half to two years. If the mileage reaches 60,000, it can also be replaced. 

          The belt is an important part of the engine's gas distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust timing. The use of belts instead of gears for transmission is due to the low noise of the belt, accurate transmission, small self-variation and easy compensation.

Timing belt (Timing belt) is an important part of the engine gas distribution system. It is connected with the crankshaft and matched with a certain transmission ratio to ensure the accuracy of the intake and exhaust timing. The use of belts instead of gears for transmission is due to the low noise of the belt, accurate transmission, small self-variation and easy compensation. It is obvious that the life of the belt must be shorter than that of the metal gear, so the belt should be replaced regularly.

The function of the timing belt is that when the engine is running, the stroke of the piston (up and down movement), the opening and closing of the valve (time), and the sequence (time) of the ignition, under the connection of "timing", keep "synchronization" at all times run.

Timing is to use the timing mechanism of the engine to make each cylinder exactly: when the piston goes up to the top dead center, the valve is just closed, and the spark plug is just ignited.

The timing belt is a consumable item, and once the timing belt breaks, the camshaft will of course not run according to the timing. At this time, it is very likely that the valve will collide with the piston and cause serious damage. Therefore, the timing belt must be in accordance with the original factory.
