Will restarting the engine after driving through water cause damage?
1 Answers
Restarting the engine after driving through water can cause damage. If the car stalls after driving through water and water enters the engine, forcibly restarting the engine can lead to bending of the engine connecting rods. Bent connecting rods can damage the engine block and crankshaft, causing significant harm to the engine, and in severe cases, may result in the engine being scrapped. Below is more information about driving through water: Reasons for stalling when driving through water: The high-voltage ignition system may become damp or short-circuited due to water ingress, causing the engine to stall. This is a common occurrence, usually caused by splashing water. Water entering the exhaust pipe can also cause stalling, as the exhaust pipe is positioned low, and if the water level rises above it, the engine cannot expel exhaust gases and stalls. What to do if the car stalls after driving through water: Do not attempt to restart the engine if the car stalls after driving through water, as this can cause severe damage or even total engine failure. Stay calm, turn off the ignition immediately, and avoid trying to start the engine. The car should be towed to a repair shop promptly to prevent further damage. After driving through water, it's advisable to check the engine compartment, air intake, wheels, brake discs, exhaust pipe, and carbon canister for any debris that might affect driving safety.
