Where can Baoding be repaired? how much is it? 1. The timing belt cannot look at the rubber surface. It is broken because the internal lacing is constantly stretched during use, and it will break if it exceeds the elongation limit. In addition, the timing belt that should be replaced during the service period should be replaced even if it is not broken temporarily, because the timing will be inaccurate after the belt is stretched, which will affect the engine performance. Generally speaking, replace 60,000-70,000 kilometers; The higher one is 8-65438+ 10,000 kilometers to replace the timing belt. The replacement time of cars of various brands and brands is different. Please check the specific provisions in the maintenance manual and replace it at the specified time.

2. If the timing belt is faulty, it is generally a precursor, and the engine will make abnormal noise. So it is very useful to hear whether the engine sound is normal. Especially when approaching the specified (or reaching) replacement kilometer, we should pay more attention to listen to whether the engine produces abnormal noise at any time. It is suggested that the engine should be replaced in advance when the specified replacement time is approaching, so as to avoid accidents or breakage in use and damage to the engine.

3. Dismantle the right wheel first, and then clear the periphery, that is, remove all generator belts, booster pump belts and air conditioning belts, and then remove the right wheel guard plate, crankshaft pulley and timing belt upper and lower covers. After aligning the position, remove the idler, the timing belt and then the tensioner. When installing, install the idler and tensioner first, but do not tighten them. Starting from the idler, install the timing belt. After pressing the timing belt, check the timing position of the upper and lower wheels. Turn it twice by hand to make sure it's all right before installing the others. The future is simple, and the future is success. Ha ha!

4. Incorrect ignition timing has a great influence on the car. The combustion of gasoline in the engine must be ignited by the spark from the spark plug. In order to make the engine start smoothly and burn well, the spark of the spark plug must be strong enough, but more importantly, the time when the spark jumps out must be appropriate and correct. Too early or too late will affect the horsepower of the engine. The moment when the spark jumps out of the spark plug is the so-called ignition moment. Generally, it is expressed by the angle of crankshaft angle before piston top dead center, such as ten degrees before top dead center, which is not timely.
