Does Water Entering the Engine Compartment on Rainy Days Have Any Impact?

[Harold]

Start the engine and let it idle for several minutes until it reaches normal temperature to dry the water and moisture on the engine. After confirming the vehicle's technical condition is good, drive at low speed for a short distance and consciously press the brake pedal lightly several times to generate heat through friction between the brake shoes and drums, drying and evaporating any residual water in the braking system to ensure optimal brake performance. If a vehicle experiences water ingress, it is best to take it to an auto repair shop or a professional after-sales service station for repairs, avoiding cheap roadside shops for maintenance. Additional Notes: 1. Remove the negative terminal of the battery as soon as possible to prevent short circuits in the vehicle's electrical components due to water exposure. 2. Immediately inspect the engine, first checking if water has entered the cylinders, as this can bend connecting rods and damage the engine. 3. Check if water has mixed with the engine oil, as this can degrade the oil, reducing its lubricating properties and causing excessive engine wear. 4. Inspect the transmission for water ingress, as water can contaminate the gear oil, leading to gear wear. 5. Check the brake fluid and all four-wheel brakes, as water in the brake fluid can degrade it, resulting in brake failure. 6. If water enters the exhaust pipe, drain it promptly to prevent impurities from clogging the catalytic converter or damaging the oxygen sensor. 7. Inspect the battery for water ingress and replace the electrolyte if necessary.
