How many kilometers to replace Sonata VIII synchronous belt?

Sonata timing belt is generally replaced within 65438+100000 km. When the car is running, the idle speed is unstable, and it is easy to stall, mainly because of poor refueling and weak acceleration, and in severe cases, the engine shakes. When these situations are found, it is a matter of time to eliminate the faults of circuit components such as throttle. If the timing belt is damaged and not replaced, the valve and piston will be damaged and the engine will not work. The following is the installation method of the timing belt: 1. Align the mark of camshaft timing gear with the mark of valve cover, and align the mark of crankshaft timing gear with the mark of front cover; 2. Install timing belts such as crankshaft timing gear, water pump pulley, idler pulley, camshaft timing gear and pulley in turn; 3. Loosen the pulley mounting bolt 1\/4- 1\/2 turns, compress the automatic tensioner push rod to the lowest position, insert it into the hole with steel needle, adjust the pulley with snap ring pliers, rotate counterclockwise to make the two adjusting holes of the pulley parallel to the ground, lock the fixing bolt and pull out the steel needle; 4. Turn the crankshaft clockwise for 2 turns, check whether the timing marks are aligned correctly, and turn back the lower cover and the upper cover of the timing belt of the right nail engine; 5, put the generator, air conditioning compressor belt back to the car, check the engine for abnormalities.
