Self tapping drain plug

Sometimes your existing drain plug can be damaged because of wear and tear and mishandling. Nonetheless, you can always replace it with a self tapping variety. When it comes to installing your self-tapping drain plug, it’s important that you know exactly how to use it to avoid damage again.

Step 1 - Clean Your Drain Hole

Before you can do anything to your drain hole, you need to make sure that you wipe off any oil in it. This is essential in finding out if your drain hole has been damaged or not. You can effectively wipe off the oil with the use of a clean shop rug.

Step 2 - Clean the Drain Plug

It’s also important that you clean your drain plug. You’ll know if your drain plug is defective because when you try to insert it inside the drain hole, it will retread instead of fitting tightly. If the extent of the damage is that severe, then you have to exchange your existing drain plug for a self-tapping drain plug.

Another way for you to find defects in your drain plug is by looking for burrs. You should also check the threads of your drain plug to see if there is anything amiss with it.

Step 3 - Start Your Self Tapping Drain Plug

Position your new drain plug inside the drain hole of your oil pan. It’s very important that you do not cross the threads when you are first starting your self-tapping drain plug. Doing so will make oil drip and leak from the drain hole, which will only bring you back to square one.

Step 4 - Tighten the Self Tapping Drain Plug

Once you are done starting the self-tapping drain plug you can continue by tightening your plug with the use of your hands. Still, it’s very important that you do not cross the threads while you are tightening to prevent any leaks from happening.

Step 5 - Use a Crescent Wrench

When you are done tightening the drain plug with your hands, you need to reinforce your work with a wrench. Adjust your crescent wrench according to the width of your self tapping drain plug’s nut. Place the wrench around the nut and tighten its grip. You can continue tightening by twisting your wrench. Expect to have a few drops of oil leak from your drain hole; this is normal. You can wipe your drain plug often if you are really particular about your crescent wrench getting dirty and greasy. Although you would want your self-tapping draining plug to fit snugly, you do not want to keep on twisting your crescent wrench to the point that you have over tightened your draining plug already. Over tightening will only cause stripping of your drain plug’s threads. This will make it possible for the oil inside your drain hole to leak out because of the tiny holes that are present where the threads have stripped.
