Is Engine Stalling Due to Water Intake Serious?
2 Answers
Engine stalling due to water intake is very serious. Here are the precautions to take after water enters the engine: 1. If the engine has been submerged in water, do not attempt to start it immediately. Starting the engine under such conditions can cause water to enter the combustion chamber, leading to bending of the engine connecting rod. 2. When the vehicle engine is running, if the road water level is higher than the engine's intake system, backflow can occur. Water may enter from the air filter to the intake pipe and then into the engine combustion chamber. 3. If the engine stalls, do not attempt to restart the vehicle. Immediately call your insurance company and a repair service to wait for assistance.
I've been repairing cars for over 20 years, and water entering the engine causing a stall is a serious issue! Water forced into the pistons can't be compressed like air, directly bending the connecting rods. In severe cases, the connecting rods can puncture the cylinder block. Two years ago, a Touareg owner tried to restart the engine after stalling in water, resulting in over 40,000 yuan in engine repairs. Remember the key point: if the engine stalls in water, turn off the ignition immediately—don't even turn it to the ACC position, as the electronic system might automatically restart! And while waiting for rescue, don't foolishly sit in the car—rising water can cause electrical shorts, making it even more dangerous.
