How to Deal with Water Ingress in the Car Undercarriage?
2 Answers
When water enters the car undercarriage, the first step is to dry it out or drain it completely. Below are specific methods for handling water ingress in the car undercarriage: 1. Drainage Method: Choose to either dry the water out or drain it completely. 2. Rust Prevention Treatment: In reality, there is always a possibility of water entering the undercarriage, but the car is designed to drain water out on its own. If water accumulates, then the undercarriage needs to be cleaned. It is also important to check if the internal self-draining system of the undercarriage is functioning properly. If not, maintenance is required. 3. Coating Method: Apply a layer of waterproof coating directly onto the undercarriage. This effectively blocks external water from entering the undercarriage.
I encountered water entering the underside of my car during the rainy season the year before last, and I was really panicked at the time. Dealing with water under the car involves three key steps: First, you must immediately turn off the engine and stop the car, especially if the exhaust pipe is submerged—never restart the engine, or it will be ruined. Second, check the water level inside, remove all floor mats, and use dry towels to soak up the water, then open all doors for ventilation. Finally, quickly contact a professional repair shop to drain the chassis. The most important thing is to check whether the electronic control unit has been soaked—last time, it cost me 800 yuan just to dry out the circuit module. Now, I always check the condition of the sealing strips every time I wash my car—that lesson was too painful.
