What Are the Solutions for a Car Radiator Leak?
2 Answers
Car radiator leak solutions are as follows: 1. Check if the radiator is cracked or corroded. If these signs are present, take remedial measures to avoid damage from installation or collision; 2. If the leak is minor, use soldering to repair the leaking area; 3. Inspect whether the radiator drain switch is leaking or if there are holes or cracks in the upper and lower water chambers, and repair them; 4. In case of an emergency, mix butter and cotton evenly to plug the leak temporarily, which can slow down the leakage rate and buy time to drive the vehicle to a repair shop. The car radiator is a key component in the vehicle's cooling system, functioning to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, and then returns to the water jacket in a continuous cycle.
Just helped my neighbor with this issue a couple of days ago! Radiator leaks can range from minor to serious. Here's what I usually do: First, clean the radiator when the engine is cold, then start the engine and wait for the temperature to rise. Use a flashlight to locate where steam is escaping. For small leaks, you can temporarily use radiator stop-leak products available at hardware stores for about ten bucks a can—just pour it into the coolant tank to buy some time. If the crack is on the plastic tank, remove it and seal it with epoxy resin glue. I once made this fix last for six months. For large cracks in aluminum radiators, professional welding is needed, costing around 200 yuan at a local repair shop. However, if the main radiator tube is punctured, you’ll definitely need a replacement. Otherwise, your temperature gauge might suddenly spike into the red zone while driving, which is extremely dangerous. Remember to flush the overflow tank when installing a new radiator.
