Using your DC Sports Red Magnetic Drain Plug is easy. First, make sure your engine is cool. Then, remove the old drain plug from your oil pan and replace it with the new DC Sports plug. Tighten it properly to avoid any oil leaks. Remember to use the included aluminum crush washer for a good seal. When it comes to maintenance, check the magnet on the drain plug regularly for debris. You can clean it with a cloth when you change your oil. Also, always ensure that the plug is tightened correctly after each oil change to keep your engine running smoothly.
