The camshafts of Geely Emgrand can be distinguished by the letters marked on them - IN stands for intake, while EX indicates exhaust. Below are the symptoms of a damaged car camshaft: 1. The car has high-voltage spark but takes longer to start, though it can eventually run. 2. During startup, crankshaft reversal may occur, accompanied by backfire in the intake manifold. 3. Unstable idle speed with severe shaking, similar to engine misfire symptoms. 4. Insufficient acceleration prevents the car from gaining speed, even when RPM exceeds 2500. 5. The vehicle exhibits high fuel consumption, excessive exhaust emissions, and black smoke from the tailpipe.

How many liters of oil should be added to a Mercedes-Benz C180?

The Mercedes-Benz C180 requires approximately 7 liters of engine oil. After adding the oil, it's advisable to check the oil level information. The oil level can be checked using the dipstick, with the optimal level being between the upper and lower marks. Excessive oil can lead to carbon buildup between the cylinder and piston, significantly increasing the likelihood of engine knocking. Method for changing engine oil: When adding oil, ensure the oil level is between the min and max marks on the dipstick. The oil level should not be below the min mark or above the max mark. If the oil level is below the min mark, it can cause insufficient lubrication in the engine, accelerating wear. If the oil level exceeds the max mark, it increases resistance during engine operation, leading to reduced power and higher fuel consumption. Always monitor the oil level carefully when adding oil. Precautions for changing engine oil: Regular oil changes are necessary. Avoid mixing different types of oil and opt for high-quality full synthetic oil. Full synthetic oil should be changed every 8,000-10,000 km, semi-synthetic every 5,000-8,000 km, and mineral oil every 5,000 km. Regularly clean the engine filter and replace the oil filter. After adding oil, sludge and carbon deposits on engine parts disperse into the oil, causing it to darken over time. Typically, the need for an oil change is determined by checking the oil's viscosity rather than its color. Insufficient oil can lead to inadequate lubrication and cylinder scoring, while too much oil can affect vehicle performance and increase fuel consumption.

What are the causes of brake pad noise?

Brake pad noise can be caused by: 1. Lack of disc surfacing leading to brake pad noise; 2. Defects in the braking system causing only partial contact between the brake pad and disc, resulting in noise; 3. Unauthorized manual grinding or modification of brake pads, reducing the contact area between the pad and disc and causing noise; 4. Frequent emergency braking, wheel lock-up, or faulty brake calipers causing prolonged overheating of the brakes, leading to brittle friction material or even cracking, which results in noise. Brake pads are friction materials fixed to the rotating brake drum or disc of a wheel. The friction linings and blocks within them withstand external pressure to generate friction, thereby achieving vehicle deceleration.
