How Many Centimeters of Water Can a Car Pass Through?
1 Answers
Water accumulation below 20 to 30 centimeters can be passed by ordinary sedans, while SUVs can handle water levels below 30 to 40 centimeters. The safest wading height is when the water does not exceed two-thirds of the tire height. Vehicle Wading Limits: The safe wading height of a vehicle depends on the position of the air intake. Most vehicles have their air intake located under the front hood, parallel to the upper edge of the headlights. As long as the wading height does not exceed the air intake position, there should be no issues. However, when driving through water, the underwater road conditions are unknown, and encountering potholes or manhole covers may lead to water entering the engine. Additionally, when the water level exceeds two-thirds of the tire height, water may flood into the car. If the water reaches the bumper or two-thirds of the tire height, continuing to drive through water poses certain risks. Wading Precautions: Turn off the air conditioning. When the air conditioning is on, the electric fan at the front of the car remains running, and the rotating fan blades can stir up water, potentially causing water to enter the engine. Therefore, it is advisable to turn off the air conditioning before wading and wait for the electric fan to stop before entering the waterlogged area. Turn off all electrical devices. Before wading, all onboard electrical equipment, such as the air conditioning, radio, dashcam, and cigarette lighter, should be turned off to prevent electrical short circuits caused by water entering the devices.
