What to Do When the Radiator Hose is Leaking?
3 Answers
Solutions are as follows: 1. If the leakage is a crack no more than 1mm or a hole no more than 2mm: Add a bottle of radiator stop-leak agent to the radiator; If you don't have a stop-leak agent at hand, for minor leaks in individual cooling tubes, you can temporarily put loose tobacco into the radiator, utilizing the water circulation pressure to block the leak with the tobacco fibers, for temporary use. 2. If the radiator cooling tube is leaking severely: You can cut off the leaking part of the cooling tube, plug the cut end with a cotton ball coated with soap, and then use pliers to flatten and crimp the cut end of the cooling tube to stop the leakage.
I've experienced coolant hose leaks several times, and it's actually quite common. First, don't panic – immediately pull over, turn off the engine, and pop the hood to locate the leak. For small cracks, you can temporarily seal them with waterproof tape to slow coolant loss. If it's a major leak, call for a tow truck right away. Never keep driving – engine overheating can lead to costly repairs. My advice: check coolant levels every few months, and always use the correct type specified in your manual when topping up. Most leaks are caused by aged hoses or loose connections, which mechanics fix by replacing the hose or tightening clamps. Safety first – delaying repairs often worsens the problem.
Never ignore a leaking radiator hose - pull over immediately to inspect. First identify the leak location: is it a loose connection or cracked hose? For minor leaks, try tightening the connection or applying sealant as a temporary fix, but don't delay - drive straight to a professional repair shop. The cooling system regulates engine temperature; leaks can cause overheating and cylinder damage with terrifyingly high repair costs. Remember to check the coolant reservoir level and add the same brand coolant if needed. I emphasize the importance of prompt action - never take chances with safety. Towing services are readily available, so don't risk driving further.
