Can You Still Drive If the Car's Radiator Is Leaking?
2 Answers
It is not recommended to continue driving if the car's radiator is leaking, as insufficient or too little water in the radiator means the engine cannot be cooled by water or antifreeze. This can cause the engine to overheat, leading to cylinder scoring or bearing seizure, which is extremely dangerous and may prevent the engine from starting. Methods to handle a leaking car radiator: 1. Check if the radiator cap is tightly secured; 2. Use an air pump to inject air into the radiator and observe where the water leaks under pressure to determine the repair plan; 3. Unscrew the engine oil filler cap and check for signs of oil emulsification—if present, the cylinder gasket may need replacement; 4. For severe leaks in the radiator tubes, cut the leaking tube at the leak point, plug it with a soap-coated cotton ball, then flatten and crimp the cut end with pliers to stop the leak; 5. If the rubber hose connection is leaking, wrap the hose clamp around the connection twice with a screwdriver and tighten it with pliers.
I remember once on a long drive, the radiator suddenly started leaking. I stubbornly drove a few more kilometers, and the temperature gauge shot up, with smoke billowing from under the hood. It nearly destroyed the engine, costing me thousands in repairs – a decision I deeply regret. The radiator is crucial for cooling the engine; a leak means losing coolant, and without this protection, the engine can overheat, leading to cylinder scoring or gasket damage, especially dangerous at highway speeds. My advice: if you notice a leak, stop immediately, turn off the engine, avoid pressing the accelerator, and call for a tow or repairs. Checking coolant levels monthly can prevent such headaches.
