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 using the appropriate tool. Place the aluminum crush washer on the new drain plug and carefully screw it into the oil pan. Tighten it securely but don't over - tighten as this could damage the threads. As you use your vehicle, the magnet in the drain plug will collect debris. When it's time for an oil change, remove the drain plug again. Check the magnet for collected debris and clean it with a rag. Reinstall the drain plug with a new crush washer each time you change the oil. Keep your drain plug in a dry place when not in use to prevent rusting.
