Can You Drive When Water Submerges the Exhaust Pipe?

[DelMarley]

You cannot drive when water submerges the exhaust pipe. The car needs to be pushed out of the flooded area before it can be used normally. Introduction to the Exhaust System: The exhaust system generally consists of the exhaust manifold (header), exhaust pipe, flexible connection (bellows), catalytic converter, and muffler. The exhaust system is almost horizontally arranged along the chassis, but the exhaust manifold is connected to the engine and is positioned higher vertically compared to other components of the exhaust system. When water has just submerged the exhaust pipe, it cannot enter the engine cylinders. After the water recedes, the water level in the exhaust pipe will definitely drop again, meaning the farther from the exhaust outlet, the lower the water level. At this point, starting the car will not cause water in the exhaust pipe to be sucked back into the engine. Starting Method: Ignite and start the car, but do not press the accelerator and let it idle. During this time, the exhaust pipe will expel a lot of water until it stops dripping, which usually takes about 8 minutes.
