Why Clean Your Radiator?

Over time, dirt, debris, and corrosion can accumulate in your radiator. This build-up can hinder your car's ability to cool the engine effectively, potentially leading to overheating and costly repairs. Regular maintenance of your radiator is part of our comprehensive auto repair services in Marion, ensuring your vehicle stays in excellent condition.

 

Steps to Clean Your Radiator

  • Gather Your Supplies: You will need a hose, a soft brush, a bucket, a cooling system cleaner, and protective gear like gloves and goggles.

  • Safety First: Before you begin, ensure the engine is cool to avoid burns. Disconnect the battery to prevent any electrical mishaps.

  • Drain the Radiator: Find the radiator drain plug at the bottom. Place a bucket underneath and open the plug to let the radiator fluid drain completely. Dispose of this fluid properly, as it can be hazardous to the environment.

  • Flush the Radiator: Use a hose to flush the radiator with water. Spray water through the top of the radiator and let it run out through the drain plug. This will help remove any loose dirt and debris.

  • Apply a Cooling System Cleaner: Follow the instructions on the cleaner's packaging. Usually, you will add it to the radiator, fill it with water, and run the engine for a specified time to allow the cleaner to work.

  • Rinse Thoroughly: After using the cleaner, drain the radiator again and rinse it with clean water until the water runs clear.

  • Replenish Coolant: Close the drain plug and refill the radiator with the appropriate coolant as specified in your vehicle’s manual. Be sure to check for leaks.

  • Reconnect the Battery: Finally, reconnect the battery, and your radiator should be clean and functioning efficiently.
