Coolant reduction is a normal phenomenon, including engine oil and windshield washer fluid, which will decrease during vehicle usage. The primary reason for coolant reduction is natural evaporation. Coolant serves to cool the car engine, which often operates at high temperatures. Since the coolant is in contact with the engine, some consumption is normal. How to choose coolant: The basic indicators of coolant are its freezing point and boiling point. On the market, coolants are available with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region. How to determine if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to low coolant, though it could also be caused by excessively high cylinder temperatures. Check the coolant reservoir. If the level is below the minimum mark (MIN), do not continue driving; promptly add coolant. Inspect the water level markings on the coolant overflow tank. The normal coolant level should be between the maximum and minimum marks. To determine if coolant is low, check the markings. If the coolant is below the minimum mark, it indicates a shortage.

What does the engine oil grade 5w30 mean?

The engine oil grade 5w30 refers to the viscosity specification of the oil, which consists of three main parts: W, the number before W, and the number after W. The number before W is 5, and the smaller this number, the better the oil's flowability at low temperatures, indicating a lower applicable minimum temperature. The number after W is 30, which represents the oil's viscosity at 100 degrees Celsius. A higher number indicates higher oil viscosity, better high-temperature resistance, and superior high-temperature protection performance. 5W30 is particularly suitable for Japanese and Korean cars, as their engines are more precise with smaller clearances. In terms of viscosity alone, 5W30 is more suitable for colder regions and winter seasons.

How to Start a Van When the Battery is Dead?

If the van's battery is dead and you need to start it, you can have a few people push the vehicle from behind. While pushing, the driver should press the clutch and shift into first gear. Once the vehicle gains some speed, the driver should quickly release the clutch and turn the key all the way. If this method fails to start the engine, you can use jumper cables to jump-start the van with another vehicle. The main reason for a dead battery is prolonged inactivity of the vehicle. When the car isn't used for a long time, the alternator cannot recharge the battery, but the battery continues to discharge, eventually leading to a depleted charge. In fact, even after turning off the engine, some systems in the car remain active, continuously draining the battery. Therefore, leaving the car unused for extended periods will result in a dead battery. It is recommended that owners disconnect the negative terminal of the battery when the vehicle won't be used for a long time. Note that disconnecting the battery's negative terminal will also deactivate the anti-theft system. Therefore, ensure the doors are locked and windows are closed before disconnecting the battery. If the battery remains in a discharged state for too long, it will negatively affect its performance and lifespan.

What are the causes of incomplete clutch disengagement?

The causes of incomplete clutch disengagement: 1. Excessive free travel of the clutch pedal; 2. Bent or deformed release levers, loose supports, or dislodged support pins, making it difficult to adjust the height of the inner ends of the release levers; 3. Improper adjustment of the release levers, where their inner ends are not on the same plane or are too low; 4. Warped driven plate steel, cracked friction discs, or loose rivets; 5. Newly replaced friction discs are too thick or the driven plate is installed incorrectly; 6. Oil leakage, air presence, or insufficient oil in the clutch hydraulic control mechanism; 7. Weakened diaphragm spring tension, worn or damaged engine mounts, or misalignment between the engine and transmission. The symptoms of incomplete clutch disengagement: When the engine is idling, pressing the clutch pedal results in gear grinding noises and difficulty engaging gears. If a gear is forcibly engaged, the engine stalls before the clutch pedal is fully released.
