How to Clean a Dirty Car Radiator?
2 Answers
To clean a dirty car radiator, follow these steps: 1. Park the vehicle and turn off the engine. Wait for the coolant temperature to drop, then open the expansion tank and add radiator cleaner. 2. Start the engine and let it idle for 5 to 10 minutes after the cooling fan starts working. 3. Turn off the engine and remove the front bumper of the vehicle. 4. Once the coolant temperature has completely cooled, drain the radiator cleaner along with the coolant. 5. Replace with new engine coolant. The radiator is a key component in the car's cooling system, and its functions are: 1. To absorb heat from the engine block and prevent the engine from overheating. 2. To use water as a heat transfer medium through the cooling water circuit, dissipating heat through large-area cooling fins by convection to maintain the engine's optimal operating temperature.
A dirty radiator is really troublesome. I had this issue with my old car before, and cleaning it requires caution. Wait until the engine cools down completely before starting, otherwise the hot liquid can cause dangerous burns. Prepare gloves and a basin to catch the old coolant, open the cap to drain the fluid, add a specialized cleaning agent, and run the car for about ten minutes to let the cleaner circulate. Then flush the radiator with water several times until the water runs clear, ensuring no residue is left to cause clogs. Finally, refill with new antifreeze and seal it properly. It's recommended to clean it every two to three years to prevent dirt buildup and avoid engine overheating damage. DIY can save money, but make sure you have all the tools and don’t cut corners. If you're a beginner and unsure, it’s best to ask a friend for help or take it to a repair shop for inspection.
