1. First remove the lower plastic protective plate under the engine as shown in the picture below.
2. After removing the skid plate, the generator belt and oil filter are exposed. Then remove the exposed generator belt as shown in the figure below.
3. The situation after removing the belt seen from the bottom is as shown in the picture below.
4. Remove the output gear from the engine crankshaft next to the oil filter, as shown in the figure below.
5. Remove the expansion tank, as this will make it easier to remove the main fixed upper bracket from the timing belt side of the engine and loosen the bolts on both sides, as shown in the figure below.
6. Attach the triangular bracket to the disassembled engine end face (note that before loosening the bracket bolts, you must use a jack to hold the crankcaseof engine oil below to prevent the engine from falling)< /p>
7. Remove the timing belt protective cover, as shown in the figure below.
8. After removing the rear protective cover, the timing gear and brown toothed timing belt are exposed, as shown in the picture below.
9. Turn the car over to make sure the marks on both gears line up with the scale marks on the engine (AUSLESS?I?EXHAUST). The I is the mark indicating the exhaust valve timing gear. , as shown in the figure below View.
10. Simply remove the old belt and replace it with the new one as shown in the picture below.
Detailed information
Regular maintenance
1. As cars become more advanced, the maintenance workload will gradually increase. Consequently, the prCar owners often think that their vehicle requires few repairs. Each car manufacturer clearly stipulates the period for regular inspection and replacement of the timing belt. As a professional maintenance technician, you must explain this to the car owner: As part of regular maintenance and comprehensive inspection, timing belt maintenance should be included. in regular maintenance procedures. If this is ignored and a faulty timing belt is not inspected regularly and replaced in time, serious consequences can result.
2. Unlike accessory drive belts, they are easily visible and easy to inspect. The timing belt is often hidden behind a cover and is only accessible depending on the layout of the engine and engine compartment. However, in most cases, the hatchTiming belt key, at least the upper part of the cover, can be removed or moved away, allowing you to carefully inspect and replace the belt. During inspection, if you notice a belt that is not well maintained and poorly tensioned, it must be replaced promptly.
Breakage inspection
1. When the timing belt breaks, if the belt is bitten, the valve will stop in the open state and the engine will stop rotating if the engine is idling; when it breaks, it means there is a gap between the piston at the top of its stroke and the open valve. In both cases of rupture, only the timing belt itself is damaged. However, if the engine is designed with an "interference fit" and the piston and valve occupy the same space and there is no space between them, other components will soon become damaged, such as the bent valve. bend, the piston is pressed, etc.
2. Just because the timing belt isn't broken doesn't mean there isn't a problem. As the belt ages, it stretches beyond what the tensioner can compensate, causing the timing gear to slip. Wear of gear teeth and adhesion of lubricating oil can also cause slippage.
3. During inspection, if the belt shows reduced hardness, abrasion, fiber breakage or cracks or cracks, it means that the belt is damaged and can no longer be used. Next, check if there is a sprocket failure. A damaged sprocket can “burn” the belt material and increase wear on the belt teeth. A faulty gear can also cause the valve train to create more resistance against the timing belt.
