Why is there water leaking from the front of the car?

Water leaking from the front of the car may be due to windshield washer fluid or coolant leakage. If it is confirmed that the fluid at the front of the car is not engine oil, then only the windshield washer and coolant systems contain liquids. Generally, first check the windshield washer pump, pump connections, washer fluid reservoir, and reservoir connections, then inspect the pipes. Here are some additional details: 1. The same applies to coolant—check the radiator body, upper and lower radiator connections, water pump, water pump connections, and pipes. The radiator filler neck has an overflow pipe; if it is overfilled, the coolant may overflow from the overflow pipe when the temperature rises. 2. There are generally two possibilities for water leaking from the car's undercarriage: one is exhaust pipe dripping, and the other is air conditioning condensation. Exhaust pipe dripping occurs when the ambient temperature is relatively low, especially in winter, and it is a completely normal phenomenon for the car's exhaust pipe to drip water.

How to Distinguish Between Semi-Synthetic and Full Synthetic Motor Oil?

Methods to distinguish between semi-synthetic and full synthetic motor oil: 1. Generally, semi-synthetic oil is often labeled as "synthetic type" or "synthetic technology," while full synthetic oil is directly labeled as "full synthetic." 2. Another method is to check for labels indicating PAO and ester oil. Only products that use these two raw materials without blending the first, second, or third base oils are considered synthetic oil. If it contains PAO or ester oil, it must be labeled as "full synthetic oil." Differences between semi-synthetic and full synthetic motor oil: 1. Semi-synthetic oil is based on mineral oil and refined through hydrogenation, while synthetic motor oil is derived from ethylene and propylene dispersed from natural gas in crude oil, refined through complex chemical reactions such as polymerization and catalysis into high-molecular lubricants. 2. Full synthetic oil has a wider temperature range and a longer service life. 3. For the same oil film requirements, synthetic oil has a lower viscosity, while semi-synthetic oil has a higher viscosity compared to synthetic oil. 4. Semi-synthetic oil is mainly used for economical vehicles, while full synthetic oil is primarily used for luxury vehicles. 5. The amount of additives differs, with full synthetic oil containing more additives and semi-synthetic oil containing fewer. 6. Full synthetic oil has better anti-aging stability. 7. Full synthetic oil provides better engine protection. 8. The price of full synthetic oil is higher than that of semi-synthetic oil.

Do brake pads have to be replaced at a 4S shop?

Brake pads do not need to be replaced at a 4S shop. Here is the method for replacing brake pads: 1. Open the engine compartment and check the brake fluid level to prevent overflow during replacement; 2. Remove the wheel where the brake is located; 3. Remove the bolts of the brake caliper and take out the brake pads; 4. Install new brake pads, tighten the guide bolts, and the replacement is complete. Additional information: 1. The working principle of brake pads is to convert the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby stopping the vehicle. 2. Types of brake pads include: semi-metallic brake pads, non-metallic brake pads, carbon fiber brake pads, and ceramic fiber brake pads.

Can I still drive with a cracked windshield?

You can still drive with a cracked windshield, but it should be repaired as soon as possible, otherwise it will affect the repair effect. More information about windshield cracks is as follows: 1. Generally speaking, the probability of cracks on the front windshield of a car is the highest, but not all cracks can be repaired. Only cracks on the outermost layer of glass can be repaired. The types of cracks that can usually be repaired are: star-shaped cracks and linear cracks. 2. If the crack diameter exceeds 20mm, the repair effect will be poor. Under normal circumstances, 4S stores do not recommend repair but suggest directly replacing the windshield.

What does the ECO mode of Volkswagen Lavida mean?

The ECO mode in Volkswagen Lavida refers to the car's economical driving mode function. ECO is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the car's economical mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, gearbox shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates driving behavior, and if the current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most vehicles employ the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, the Eco mode can be activated. However, it is unnecessary to activate Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills, as it does not reflect the economical and fuel-saving characteristics of Eco. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, and the Eco mode automatically deactivates. During idle parking or in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function.

How to Turn On TRC When It's Off?

If the car displays that TRC is off, the owner can turn off the engine and then restart it to automatically activate TRC. Here are some related details: 1. The TRC system refers to the Traction Control System. 2. TRC is a term specifically used for Toyota models. It is designed to effectively maintain driving force and prevent the drive wheels from spinning when starting or accelerating on slippery roads, thereby enhancing driving safety to some extent. 3. Driving is not affected when the TRC system is turned off. However, the engine will not reduce power output if the wheels slip, which may cause the drive wheels to spin on wet or slippery surfaces. 4. As an auxiliary driving system, TRC helps improve driving stability. Therefore, it is generally recommended not to turn off the TRC system under normal driving conditions. However, if the vehicle is stuck in mud, sludge, or snow, the owner can manually turn off TRC to increase the engine's power output to the wheels, helping the vehicle escape from being stuck.
