The wading depth of a minivan is 30-60 centimeters. Here is some additional information: 1. Vehicle wading depth standards: Different vehicle models have different wading depth standards. The wading depth for sedans is 20-30 centimeters, for SUVs it is 30-60 centimeters, and for hardcore off-road vehicles it can reach 70-100 centimeters. Generally, as long as the water level does not exceed the height of the engine intake, there should not be significant issues. Even if the water level submerges the exhaust pipe, the strong exhaust pressure can blow the water out of the pipe. When wading, it is advisable to maintain a low gear to prevent the vehicle from stalling. 2. Problems after vehicle wading: Deformation and damage to the crankshaft connecting rod mechanism. When a mixture of water and air enters the engine through the intake, since gases are compressible but liquids are not, the connecting rod can deform under the influence of water. If the driver attempts to start the car at this point, the significant reaction force can cause the bent connecting rod to rub against the cylinder block, resulting in irreversible damage to the cylinder block.

As a frequent camper who often drives a van to suburban areas, I have some insights on wading depth. Generally, the wading depth of a van is around 25 to 40 centimeters, but it depends on the vehicle design and ground clearance. For example, models with higher air intake positions are more water-resistant. Once, I drove through a small stream, and when the water reached halfway up the wheels, I felt something was wrong—the engine almost stalled. Later, I found water had entered the exhaust pipe, but luckily, there was no major damage. For safety, it's best to measure the water depth with a stick before wading, maintain a slow and steady speed, and avoid sudden acceleration or stopping. During the rainy season, I always avoid deep waterlogged areas, even if it means taking a longer route. Wading too deep not only damages the engine but also affects components like the brakes, leading to expensive repairs. Regular maintenance should also check if the sealing strips are aging.

Where is the Previa engine number located?

The Previa engine number is located at the rear of the engine. It is situated at the junction between the timing cover and the cylinder block. For the 6-cylinder version, it's on the side closest to the firewall. Typically, it consists of a 7 to 8-digit combination of numbers and letters. In addition to the above method, the engine number can also be found through the following 4 ways: The vehicle registration certificate displays the engine number, usually on the second last line; The motor vehicle registration certificate records the engine number; The car purchase invoice states the engine number; The vehicle purchase tax payment certificate indicates the engine number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's range, and engine models can be identical. The engine number, however, refers to the production serial number of the engine. Each engine can only have one unique engine number, and no two engines share the same number.

Why can't the 3rd gear of the Baojun 560 manual transmission suddenly engage?

Manual transmission can't engage gears for the following reasons: Incorrect gear position: When starting an automatic transmission car, the gear must be placed in P or N position. If placed in R or D position, the car will not start. Some manual transmission cars will also not start if the clutch is not depressed. No antifreeze added: Some car owners add water or inferior antifreeze to their cars, resulting in the entire water circuit freezing in extremely cold winter conditions, causing the engine to crack, the car water pump to fail to operate, the car not to start, and damage to other engine components. Gear lever assembly failure: The internal gears of the gear lever are worn, causing the gear lever to get stuck, making it very difficult to pull back and forth, resulting in the inability to shift gears and difficulty in shifting.
