What is the fastest way to repair a leaking radiator?
2 Answers
Solutions for car radiator leaks are as follows: 1. Pipe rupture: When the car is running and a pipe ruptures causing a leak, if the crack is no more than 1mm or the hole is no more than 2mm, add a bottle of radiator sealant to the radiator and start the engine; 2. Oil emulsification causing leakage: Disassemble the engine and replace the cylinder gasket; 3. Loose radiator cap causing leakage: Check and securely fasten the cap; 4. Rubber pipe joint leakage: Use a screwdriver to adjust the rubber pipe joint, then tighten it with pliers; 5. Radiator cooling pipe rupture: Add a bottle of radiator sealant to the radiator, start the engine, then cut off the leaking cooling pipe at the leak, block the cut end with a soap-coated cotton ball, flatten the cut end with pliers, and crimp the edge to stop the leak.
That time on the highway when the radiator leaked, I quickly pulled over and turned on the hazard lights to prevent engine overheating and damage. As someone who frequently drives long distances, the quickest fix is using an onboard leak sealer: locate the leak point, pour it into the coolant reservoir, start the engine for a few minutes to let it circulate and seal. It's suitable for small cracks in emergencies, but for large leaks, towing is necessary. Always wear gloves to prevent burns when handling. Afterwards, go to a professional shop immediately to check the cause, such as aging or corrosion. Looking back, acting promptly saved my engine. For regular maintenance, don’t forget to replace the coolant to prevent rust, and it’s always wise to carry a can of leak sealer on long trips.
