What Causes Water Leakage from the Car Chassis?
3 Answers
Reasons for water leakage from the car chassis: 1. The low temperature of the evaporator box in the air conditioning system causes hot air inside the car to condense into water droplets, which then flow out through the drain pipe; 2. Radiator leakage usually occurs below the radiator, i.e., between the front bumper and the engine, and the car dashboard will typically issue a warning; 3. If the leaking water is colored, it indicates a problem in the cooling system, and the car should be inspected and repaired. Methods to maintain the car chassis: 1. Chassis sealing, which mainly resists acid and alkali corrosion, preventing harmful substances from damaging the chassis; 2. Regular cleaning and rust prevention. After driving for a while, if there is excessive mud or dirt on the chassis, use a degreasing cleaner to wash it, revealing the chassis's original color, before starting rust-proof treatment.
I've been driving for fifteen years and have encountered chassis leaks several times, each time giving me a headache. The most common is the condensation water dripping from the air conditioning, which is normal—clear, colorless, and odorless. If parked under a tree, you might hear a ticking sound, but there's no need to worry. However, if it's not AC water, you should be alert: for example, red power steering fluid leakage will make the steering wheel heavier; green coolant leakage indicates a problem with the radiator or water pump connection, and the engine might overheat; black or brown engine oil leaks come from a cracked oil pan or seals and can pollute the road. Early detection and repair save money and ensure safety—don’t make the same mistake I did the first time by delaying until the engine was ruined, costing me 8,000 yuan for new parts. The inspection method is simple: after parking, place a tissue to absorb the water—different colors are warning signals.
As a car enthusiast, I noticed water stains on the chassis of my new car within a year and promptly went to check it out. Chassis water leakage can originate from several areas: Air conditioning system dripping is a normal physical phenomenon, more noticeable in high humidity; Abnormal leaks like coolant leakage could be due to radiator cracks or aging pipes, with the coolant appearing green or yellow and having a sweet smell; Windshield washer fluid leaks usually occur near the front wheels, the water is clear and odorless but will disable the washing function; Sometimes engine bottom oil seal damage can cause oil leaks. My suggestion is to first inspect it yourself: Check if the fluid level is below the MIN line, locate the leakage point, observe the water's color and smell, and address it promptly to avoid body corrosion or expensive repairs.
