What Causes Car Radiator Leakage?

[Lydia]

Car radiator leakage can be caused by burst hoses, emulsified engine oil, loose radiator cap, leaking rubber pipe joints, cracked cooling tubes, or radiator damage. The car radiator, also known as the heat exchanger, is a key component in the vehicle's cooling system. Emergency measures for car radiator leakage: When the leak involves cracks no larger than 1mm or holes no bigger than 2mm, add a bottle of radiator sealant to the radiator and start the engine. After 5-10 minutes of opening the coolant for major circulation, all leaks in the cooling system—whether in the radiator, rubber hoses, or gaskets—will stop. The sealant doesn't need to be drained and won't affect heat dissipation or cause blockages. If no sealant is available, for minor leaks in individual cooling tubes, you can temporarily place loose tobacco strands into the radiator. The water circulation pressure will cause the strands to clog the leak points in the cooling tubes. For more severe leaks in radiator cooling tubes, cut off the leaking section of the tube, plug the cut end with a soap-coated cotton ball, then use pliers to flatten and crimp the tube end to stop the leak. For leaking rubber pipe joints, immediately wrap the joint clamp twice around the leaking area with a screwdriver, then tighten it with pliers. If the rubber hose is damaged, temporarily wrap the cracked area tightly with adhesive tape.
