What are the effects of water reaching the car chassis?
2 Answers
If water reaches the car chassis, there is generally no problem, as this depth will not damage the car's components. Here are some key points to note when water enters the car chassis: 1. Rust prevention treatment: When cleaning the water from the chassis, it is also important to pay attention to rust prevention. You can use automotive-specific rust inhibitors for rust removal. Special attention should be paid to whether the universal joints, bolts, and transmission mechanisms have rusted. 2. Car maintenance: It is recommended to take the car to a 4S shop or repair shop for maintenance and to check for any leaks. Special attention should be paid to the braking system and brake discs to see if there are any abnormalities or rust caused by water. 3. Check for circuit and oil line blockages: Inspect the car chassis's circuits and oil lines for any faults or blockages. If professional inspection is required, it can be handed over to maintenance personnel. You can also check the carpets and electric seats for any signs of water damage.
After my car was submerged up to the axle height last time, the chassis soaked overnight, resulting in a series of troubles. Severe rust developed underneath the chassis, with components like suspension springs and brake lines corroding, requiring costly replacements of flood-damaged parts. Especially if water entered the engine or transmission, the mechanic said it might be directly totaled and unable to start. Even worse, the wiring harness short-circuited, causing all dashboard warning lights to illuminate and the ABS system to fail, making driving in rainy conditions nerve-wracking. Water also seeped into the cabin, leaving a musty odor that forced me to keep the windows open for ventilation daily. The long-term impacts are significant: the resale value plummeted, insurance premiums rose or claims were denied. It's advised not to start the engine after flooding and to tow it to a professional shop immediately to avoid losing tens of thousands like I did. Regular inspections of the chassis rustproof coating can reduce corrosion risks.
