The second maintenance items for a car include changing the engine oil, replacing the oil filter, replacing the air filter, and replacing the cabin air filter, etc. Car maintenance is actually quite simple; it mainly involves the replacement of various fluids and wear-prone components. The fluids in a car include engine oil, coolant, brake fluid, power steering fluid, and transmission fluid, among others. The wear-prone components on a car include belts, various filters, wiper blades, tires, brake pads, brake rotors, spark plugs, ignition coils, etc. During maintenance, the focus is on replacing these fluids and wear-prone components, as well as inspecting other parts that are prone to wear. Spark plugs also need to be replaced regularly, as prolonged use without replacement may affect the engine's performance.

I just had my car's second maintenance, which was basically a routine service package. The most crucial part was changing the engine oil and oil filter, which is like giving the engine a deep cleanse. The air filter also needs to be replaced or cleaned depending on its condition, otherwise the engine will struggle to breathe. I asked the mechanic to measure the brake pad thickness and found out the front ones were already half-worn! Adjusting the tire pressure to 2.5bar is most fuel-efficient, and they also did a tire rotation for more even wear. All fluids were checked, with the coolant topped up to the middle line. If the steering feels heavier, it might be a power steering fluid issue that needs special attention. The chassis should be lifted for thorough inspection - my exhaust pipe hanger was loose last time. The cabin air filter often gets overlooked; when opened, it was full of leaves, and after replacement, the AC airflow became noticeably cleaner. The whole process took two hours, and the car felt more responsive when driving afterward.

Last month during the second maintenance, I specifically consulted a senior technician. The second maintenance is essentially a full vehicle health checkup. The mandatory items include engine oil and filter replacement, which is like giving the heart a blood transfusion. Last time, my car was found with coolant below the minimum level, and topping it up prevented overheating risks. The brake system was a key inspection point—they used calipers to measure the brake pad thickness, and I personally saw that the rear wheels still had 5mm of life left. Three aspects of the tires were checked: tire pressure, tread wear, and stone entrapment. Adjusting the tire pressure can reduce fuel consumption by 3%. The lighting test was practical; I didn’t even know one of the reverse lights was out. The undercarriage inspection revealed a loose battery bracket, which was tightened in time to avoid short circuits from bumps. The cabin air filter is recommended to be replaced annually, especially in spring when pollen is abundant. Finally, a full vehicle computer scan cleared two false alarm codes. The total cost was over 600, but catching issues early is more cost-effective.

What is the working principle of engine valves?

The working principle of engine valves is driven by the camshaft through tappets and push rods. Symptoms of engine valve leakage: Valve leakage leads to weak vehicle performance, excessively rich or lean air-fuel mixture, incomplete combustion of fuel in the combustion chamber, resulting in increased fuel consumption; Valve leakage can also cause slow acceleration. Engine valve leakage can make the engine difficult to start, reduce power, cause incomplete combustion, severe carbon buildup, and even lead to individual cylinders not working. Causes of engine valve leakage: Valve burning leads to decreased sealing between the valve and valve seat; Valve clearance adjusted too small, causing the valve to not close tightly; Carbon buildup on the conical surface of the valve and valve seat; Foreign objects stuck during valve installation causing poor sealing; Pitting, scratches, spots, burns, or dents on the valve working surface; Poor grinding of valve sealing rings during maintenance; Excessive runout of the valve and valve stem; Excessive coaxiality deviation between the valve guide hole and seat hole.

What is the torque specification standard for Volkswagen vehicles?

Automotive cylinder head connecting rod cap crankshaft cap bolts have a torque of 8 for the main bearing cap and 6 for the small bearing cap. The compression ratios of engines vary by model, so the bolt torque specifications also differ. The standard torque specifications for Volkswagen vehicles are as follows: 1. Class A: Iron screws fixed with iron nuts (threaded holes). For example: assembly of various components in the housing; grounding screws and nuts. 2. Class B: Iron screws with copper nuts (threaded holes and aluminum alloy threaded holes). For example: fixing transistors or wire terminals on aluminum heat sinks; fixing aluminum heat sinks on PCBs; fixing screws for large capacitors or transistor terminals; fixing RS-232 hexagonal copper pillars. 3. Class C: Iron screws locked into plastic holes. For example: fixing plastic panels to the housing; fixing PCBs on plastic panels. 4. Class D: Iron screws locked into tapped holes with a plate thickness of 1.0.

How to Pass the Color Vision Test for Driver's License Renewal?

Here are methods to pass the color vision test for driver's license renewal: 1. Take the test under sufficient lighting: The more adequate the lighting, the more saturated the colors will appear, making it easier for individuals with color vision deficiency to distinguish them; 2. Wear color-correcting glasses: Whether for color vision deficiency or myopia, wearing glasses is permitted during the driver's license medical examination. Therefore, individuals with color vision deficiency can purchase corrective glasses from professional stores to enhance their perception of color contrast; 3. Inform the staff about your condition: Medical personnel will arrange a different color blindness test upon understanding the situation, which increases the chances of passing for individuals with color vision deficiency. Additional information: Color vision deficiency is not the same as color blindness: Color vision deficiency, also known as color vision defect, can be understood as a mild form of color blindness where individuals can recognize colors but with reduced sensitivity. The most intuitive difference is that color blindness prevents color recognition, while color vision deficiency merely impairs color recognition ability, making colors distinguishable only when they are highly saturated. The most common types are red deficiency (protanomaly) and green deficiency (deuteranomaly), with blue deficiency being extremely rare.
