The slight water seepage at the upper edge of the car radiator is serious. The car radiator is an important component, and if there is a problem with the radiator, the vehicle will be greatly affected. The radiator must be replaced if it is leaking: Water seepage in the radiator is generally caused by a crack in the radiator or a broken pipeline, which is a relatively serious fault. If the radiator leakage is not dealt with in time, it will cause the complete leakage of the antifreeze, and then the car will have a high-temperature alarm, seriously affecting the operation of the vehicle. Do not continue driving: After the radiator leaks, the vehicle is prone to overheating. If the vehicle temperature is too high, it can cause engine cylinder damage or cylinder scoring problems.
Last time I was driving, I noticed a slight water seepage from the upper edge of the radiator. At the time, I thought it was a minor issue and ignored it. A week later, the leakage worsened, and all the coolant drained out, nearly causing the engine to overheat and stall. When I took it to the repair shop, the mechanic said it was due to a worn-out and loose sealing ring. Replacing it cost less than 50 yuan to fix. The cooling system is the core defense for protecting the engine—even a small leak weakens this barrier. Prevention is key. I recommend checking coolant levels and potential leak points as soon as you notice any issue, rather than letting a minor problem escalate into a major repair that could cost thousands in engine damage. Get into the habit of inspecting the radiator monthly—it saves money, hassle, and most importantly, keeps you safe.
