What Causes the Car to Shake and the Malfunction Light to Illuminate?

Car shaking with the engine malfunction indicator light on may be caused by engine misfire, excessive carbon buildup in the intake system, or issues in the ignition system. More information about the malfunction light is as follows: 1. If after the malfunction indicator light comes on, the car drives without any abnormal sensations, and acceleration and braking are all normal, then the vehicle can currently be driven normally. It could be that a certain sensor has malfunctioned but has now returned to normal. It may also be due to interference from certain external conditions, where this malfunction does not affect the vehicle's operation but may have some impact on emissions. In this case, you can temporarily continue driving and then go to a repair shop for inspection. 2. If after the malfunction indicator light comes on, the vehicle indeed has abnormalities, such as severe shaking, lack of power during acceleration, etc. In this situation, do not continue driving; request emergency towing service.

What is the Difference Between a Power Sunroof and a Panoramic Sunroof?

Power sunroofs and panoramic sunroofs differ in terms of area coverage and manufacturing costs. Below is a detailed comparison between the two: Difference in Area Coverage: Panoramic sunroofs are larger than power sunroofs, covering about two-thirds of the roof. However, some panoramic sunroofs cannot be opened, while others can open up to only half of their area. Power sunroofs cover approximately one-third of the roof and are operated by an electric motor. Pressing the switch button automatically opens the sunroof, and it can be stopped at any desired position. Difference in Manufacturing Costs: Due to their larger size, panoramic sunroofs have relatively higher manufacturing costs. In contrast, power sunroofs, being smaller in size, have relatively lower manufacturing costs.

What kind of engine oil should be used for the 1.5T Ford Kuga?

5W-20 is the recommended engine oil type for the 1.5T Ford Kuga, and it is best to use fully synthetic oil. Since the 1.5T Kuga is equipped with a turbocharged engine, the turbocharger operates under high temperatures and high speeds. Without fully synthetic oil, the engine may not receive adequate protection, leading to potential damage and reduced engine lifespan. The viscosity of engine oil changes with temperature, so it is crucial to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means the oil can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the vehicle. The second number represents the oil's kinematic viscosity at 100°C. A higher value indicates better viscosity retention at high temperatures, which can also be understood as improved lubrication performance under high-temperature conditions. The method for changing the oil in the Chevrolet Orlando is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to collect the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passages to drain out. Use a specialized wrench to remove the oil filter. Apply a thin layer of oil to the gasket of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine's valve cover, typically filling up to three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to ensure the oil level is within the standard range.

The Difference Between Mineral Oil and Semi-Synthetic Oil

Mineral oil and semi-synthetic oil differ in the following aspects:1. Price difference: Mineral oil is based on petroleum-refined mineral oil with additives, making it relatively cheaper; synthetic oil is more expensive. 2. Performance difference: Mineral oil, being cheaper, provides basic protection and is the most fundamental type of oil; synthetic oil is entirely synthesized and differs from mineral oil, offering superior lubrication for the engine. Its high and low-temperature performance and high-speed lubrication are outstanding, typically used in high-end cars, racing cars, and vehicles in extreme climates. 3. Engine noise: In terms of engine noise, there isn't a significant decibel difference between using mineral oil and synthetic oil in the same car. The only difference lies in the sound quality—engines using full synthetic oil produce a more pleasant and powerful sound compared to those using mineral oil. 4. Power output: Initially, there isn't much difference between mineral oil and synthetic oil in terms of power output. However, over time, the power output with mineral oil tends to decrease linearly. After driving 3,000 kilometers, it becomes evident that synthetic oil maintains a much stronger power output.

What is the shelf life of wiper blades?

The shelf life of wiper blades is not fixed, usually around one year. When the wipers show the following conditions, they should be replaced promptly. The specific situations are as follows: 1. Damage symptoms on the wiper blades: Visually check for cracks, rust, deformation, attachments, discoloration, etc. 2. Streaks on the windshield: During the use of wiper blades, if there are thin streaks left on the windshield, making it difficult to see outside, you can first clean the edge of the wiper. If the symptom persists, replacement is needed. 3. Wiper blades making harsh noises: If the wiper blades produce noise or jump and cannot rotate smoothly, it may be due to wax on the glass, wear of the rubber strip, damage to the arm and bracket, or aging and deformation of the rubber strip. First, clean the windshield. If the symptom persists, replacement is required. 4. Spotted water marks left after wiping: This is caused by rubber deformation or irregular wear, where the rubber fails to contact the glass surface, indicating that the wiper bracket is deformed and needs replacement.

How to Distinguish the Valve Springs of the Axela?

Axela's intake valve uses short springs, while the exhaust valve uses long springs. The function of automobile valves is specifically responsible for introducing air into the engine and expelling the exhaust gases after combustion. Structurally, they are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion; the exhaust valve's role is to expel the burned exhaust gases and dissipate heat. Symptoms of damaged automobile valves are as follows: 1. Affecting the engine's working efficiency, resulting in reduced vehicle power; 2. Producing abnormal noises, the engine may experience unstable idling or poor acceleration during operation, with reduced overtaking performance. In severe cases, it may also lead to difficulty starting the engine, failure to ignite, and phenomena such as air leakage or increased carbon deposits in the vehicle; 3. Damaged valves can cause unstable cylinder operation, leading to engine shaking, lack of engine power, and may also result in blockage of the exhaust pipeline. In severe cases, it can cause the exhaust to emit black smoke.
