1. Do not look at the rubber surface of the timing belt. It breaks because the tie bars inside are continually stretched during use. If the timing belt exceeds the stretch limit, it will break. Additionally, the timing belt should be replaced at the end of its life, even if it is not temporarily broken, because the timing will be inaccurate when the belt is stretched, affecting engine performance. Generally speaking, the lower range is 60,000 to 70,000 kilometers; the upper range is 80,000 to 100,000 kilometers. The replacement time of different brands and brands of cars is different. You can check the service manual for specific regulations and simply replace it according to the specified time.
2. If the timing belt is faulty, there are usually precursors and the engine will make noises anormal. Therefore, it pays to listen regularly to see if the engine sounds normal. Especially when the mileage required for replacement is near (or reached), you should pay attention at all times to whether the engine is making abnormal noise. It is recommended to replace it in advance when the specified replacement time approaches, to avoid accidents or engine damage caused by breakage during use.
3. First remove the right wheel, then clean the surrounding area, i.e. remove the generator belt, electric pump belt and air conditioning belt. Then remove the right wheel guard, crankshaft pulley. and upper and lower cover of the timing belt. After aligning the position, first remove the idler pulley, remove the timing belt, and then remove the tensioner pulley. When installing, first install the pulleynsion and tighten it. Install the tensioner pulley but do not tighten it. Next, install the timing belt, starting at the tension pulley side. After pressing the timing belt, check the timing of the upper and lower wheels. .temporal position. Turn it twice by hand to confirm there is no problem before installing more. Now it will be easy and now it will be successful. Haha!
4. Improper ignition timing has a big impact on the car. The combustion of gasoline in the engine must be ignited by sparks coming from the spark plug so that the engine starts smoothly and burns well. The spark plug must be strong enough, but more importantly, the timing of the spark must be appropriate and correct. Too early or too late will affect engine power. This is called ignition timing. It is usually expressed in terms of nonumber of crankshaft angles reached by the piston before top dead center, for example ten degrees before top dead center, rather than in units of time.
