The reasons why a van suddenly stalls and fails to start while driving are as follows: 1. Abnormal fuel supply: When it is confirmed that there is fuel in the tank, check whether there is fuel in the carburetor. If there is no fuel, it means the fuel line from the tank to the carburetor is blocked and should be cleaned and unclogged. If there is fuel in the carburetor but the engine still cannot start, check whether the carburetor fuel filter is blocked or if the main jet is dirty. 2. Engine overheating: Excessive temperature and poor lubrication can cause the piston and cylinder to seize, leading to stalling. After diagnosis, check whether there is lubricating oil in the crankcase. If there is little or no lubricating oil, check whether the oil pan or drain plug is leaking, or simply add the specified lubricating oil.

How many kilometers should transmission fluid be replaced?

Transmission fluid should be replaced approximately every 80,000 kilometers. The functions of transmission fluid include cooling, lubrication, and power transmission. The method for changing transmission fluid is as follows: 1. Remove the transmission guard plate, loosen the screws on the oil pan, and drain the old transmission fluid; 2. Unscrew the screws on the oil pan and remove the oil pan; 3. Apply sealant to the new oil pan and tighten it; 4. Loosen the screw on the left side of the transmission to add new fluid. The consequences of not changing transmission fluid include: 1. The transmission fluid will become thicker, obstructing the transmission cooler; 2. The fluid will deteriorate and its viscosity will decrease, causing the fluid particles to enlarge or produce debris that blocks the oil passages; 3. Accelerated wear of mechanical components, damaging the automatic transmission planetary gear set and differential; 4. Corrosion of the gears inside the transmission.

What is the best position for adjusting the rearview mirrors in Subject Three?

For the rearview mirror in Subject Three, adjust it so that the door handle is at the intersection of the 'midpoint vertically and the one-third line towards the car side'. Center rearview mirror: When adjusting, set the left and right positions so that the left edge of the mirror just cuts off your right ear in the reflection. This means that, under normal driving conditions, you cannot see yourself in the center rearview mirror. For the vertical position, place the distant horizon at the center of the mirror. Left rearview mirror: For the vertical position, place the distant horizon at the center. For the left and right positions, adjust so that the car body occupies 1/4 of the mirror's area. Because the driver's seat is on the left, it is not easy for the driver to see the right side of the car. Additionally, for roadside parking needs, the right rearview mirror should have more ground area visible, about 2/3 of the mirror's area. For the left and right positions, adjust so that the car body occupies 1/4 of the area.
