12626901 Engine Exhaust Camshaft Replaces 636468 Fits 2013-2023 2.0L Engines

Common symptoms in bad Camshaft include abnormal wear, abnormal noise or fracture etc.

• The car has weak acceleration and cannot run, but it is better to exceed 2500 rpm
• The increase in fuel consumption of cars
• After the engine fault light detects a sensor malfunction, it will light up the fault indicator light
• Unstable idling and severe shaking of the car, similar to a cylinder shortage fault;
• During the start-up process, there may be a phenomenon of crankshaft reversal and tempering in the intake manifold.

Why Replace?

• Abrasion : The camshaft is a high-strength component that may experience wear and tear during long-term use, leading to the loss of its original smoothness and hardness, and even the possibility of breakage. Over time, the contour on the surface of the camshaft will gradually deform, thereby affecting the opening and closing of the valves.
• Improper use : Due to improper usage by car owners, such as frequent overloading, aggressive driving, and prolonged idling, the engine can be exposed to excessively high temperatures, resulting in the camshaft bearing excessive pressure and losing its original performance, even leading to fracture.
• Rust : Engines stored in humid environments may experience rusting, and if the camshaft is not protected and lubricated in a timely manner, it is prone to wet corrosion, causing wear on the camshaft and ultimately affecting the performance and service life of the car.
• The best way to avoid this situation is to regularly maintain and upkeep the car.

How to check the wear of the camshaft

The surface of camshaft. Generally speaking, the surface of the camshaft needs to be kept flat and smooth, without cracks and scratches. If abnormal conditions are found on the surface, it is highly likely that wear or damage has occurred. The surface of the camshaft can be inspected with the naked eye or with equipment such as a magnifying glass.

The rotation of camshaft. It is necessary to check the rotation of the camshaft as it directly affects the stability of the engine. If there is vibration or noise, it indicates that the camshaft may be loose or worn. Generally speaking, manual sensors and other tools can be used to perform rotation checks.

The installation of camshaft. The installation of the camshaft is crucial, as improper installation may cause wear or damage to the camshaft. When checking the installation of the camshaft, it is necessary to ensure that the bearings are installed evenly, the bearing housing slides freely, and the wear of the shaft sleeve is controlled.

How should we maintain the camshaft?

• Regularly replace the engine oil.Oil plays a lubricating and cleaning role in the engine, which can reduce camshaft wear, so it is important to change the oil regularly.
• Use high-quality engine oil.The quality of engine oil is directly related to the performance and service life of the engine, so it is recommended to choose oil with more reliable quality to protect the camshaft.
• Pay attention to the working status of the engine.The engine needs to maintain a stable state during operation, and overloading and excessive fatigue operation are prohibited.
• In summary, the wear and damage of the camshaft may affect the performance and service life of the engine, so special attention should be paid to inspection during daily maintenance. Taking appropriate maintenance measures can effectively extend the service life of the camshaft, thereby ensuring the stable operation of the engine.
