What to Do When a Car's Underbody is Scraped and Leaking Water?

When this situation occurs, car owners need to check which part of the underbody is leaking water and then go to a 4S shop to repair the leaking part. The details are as follows: Determine Whether It's Water or Oil Leakage: When there is liquid leakage from the underbody, it is crucial to identify whether it is water or oil. Most family cars or SUVs are front-engine, front-wheel-drive vehicles, with components such as the engine oil pan and transmission oil pan located in the front half of the underbody. If the engine oil pan or transmission oil pan is damaged, it will result in oil leakage from the underbody. Avoid Damaging the Pipes: There are many pipes on the car's underbody, and if these pipes are damaged, oil leakage can also occur. Some rear-wheel-drive cars with longitudinally mounted engines have their engines and transmissions arranged longitudinally. The transmission oil pan of such cars is usually located in the middle of the body, so care must be taken while driving to avoid damaging the transmission oil pan.

A leaking car after hitting the undercarriage is a serious issue. I've seen many similar cases in my over 20 years of driving. If you notice water or liquid dripping from the underside of the car immediately after the impact, you must stop the engine right away and turn on the hazard lights for safety. After getting out of the car, don't impulsively check the undercarriage. If the liquid is green or blue, it might be coolant leaking, indicating a broken radiator; if it's oily, it could be a fuel tank or transmission oil leak. Never continue driving, as the engine could overheat and fail or even cause a fire. It's advisable to call your insurance company or a rescue service on the spot to tow the car to a professional repair shop. After repairs, make sure to have the mechanic thoroughly inspect the undercarriage protection and suspension system. To prevent future impacts, avoid potholes when driving and consider installing undercarriage armor for added protection.

I've handled similar incidents before. The most common causes of leaks after scraping the undercarriage are damage to the radiator or oil pan. If you notice a leak, immediately pull over and turn off the engine, then check the nature of the leaking fluid: coolant is usually green, while oil may appear black. If you can't handle it yourself, call for a tow truck—don't risk driving. A leaking vehicle is prone to engine overheating issues, and repair costs can start from several thousand yuan. During routine maintenance, regularly inspect the rubber bushings and protective plates under the car, and always slow down when going over speed bumps. Long-term neglect can lead to chain reactions like engine seizure, which is not worth the risk.

I've also experienced the situation where the undercarriage was scraped and started leaking. Simply put, don't touch the car after parking and turning off the engine. Get down and observe the type of leaking fluid. If it's clear liquid, it might be air conditioning condensate; green or blue indicates a cooling system leak, while oily fluid is dangerous. If you lack experience, don't attempt any repairs—call for professional towing assistance. Always pay attention to road conditions while driving to avoid bumps and prevent similar incidents from happening again.

Last time when I was on a road trip with my friend, his car scraped the undercarriage and started leaking water, which really freaked me out! I immediately told him to pull over, turn off the engine, and check it out—only to find coolant leaking everywhere. We quickly found a safe spot by the roadside, turned on the hazard lights, and called for a tow truck. The tow truck driver said if we had kept driving, the engine might have been damaged, costing even more money—thankfully we stopped in time. Later, when getting the car repaired, he even added a sturdier undercarriage guard. I recommend everyone regularly inspect their car's undercarriage to minimize risks.
