What are the steps for cleaning a car radiator?
1 Answers
Cleaning a car radiator involves the following 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 5-10 minutes after the cooling fan starts operating. 3. Turn off the engine and remove the front bumper. Ensure all mounting screws are loosened before slowly removing the bumper from both ends toward the center to avoid breaking any clips. 4. After the coolant has completely cooled, drain the radiator cleaner along with the old coolant, then refill with new engine coolant. Precautions for radiator cleaning: 1. Always ensure the coolant has fully cooled before opening the expansion tank cap. 2. If opened while hot, pressurized steam in the cooling system may cause the coolant to spray out suddenly, posing a risk of personal injury.
