Why Does a Car Stall When Wading Through Water?
1 Answers
When the water depth exceeds the exhaust pipe, the increased exhaust resistance makes it easier for the engine to stall if the throttle is too small and the engine speed is insufficient to counteract the exhaust resistance. Below are relevant details: 1. Impact: Problems arise when water reaches above the tire level. The biggest concern when wading through water is the potential damage to the engine and electrical systems. Water entering the engine's air intake directly affects the engine, and the electrical system is highly sensitive to water. Therefore, water levels must not exceed the tire height to prevent water from entering the cabin or the engine. 2. Precautions: If the vehicle stalls while wading, never attempt to restart it immediately. Forcing a restart can cause the engine to ingest more water, leading to severe engine damage.
