Cross-Threaded Oil Drain Plug Solutions


Recommended Posts

Ideally an oil drain plug should always thread in and out easily. It isn’t a structural fastener, just a plug to hold back fluid. But it can be awkward laying under a car trying to get an oil drain plug started when you feel a little resistance. Maybe it is just a piece of crud and the plug will free up in another turn. Except it doesn’t free up and now it is tight and nowhere near seated. Or just as bad the plug now turns freely but doesn’t seat. Now you have a problem. Let’s take a look at how to fix a cross threaded oil drain plug and other oil drain plug problems.

. This special tool typically comes as a kit with several different thread sizes. Pick the repair tool with the thread size that matches your oil drain plug. Apply a few drops of lubricant to the repair tool and gently thread it into the oil drain plug hole turning it slowly by hand. The repair tool will repair the threads as it goes. Be careful to not allow the repair tool to pass completely through the oil pan drain plug hole, stay within the threaded area. Use a new oil pan drain plug (the old one may be damaged) and thread it in gently by hand to verify the repair.

How To Fix A Stripped Oil Drain Plug Hole

The first step in how to fix stripped oil drain plugs is to not panic. Once you realize that the oil drain plug won’t tighten, immediately stop turning it. Try to reverse the drain plug out of the hole by hand. If the drain plug only spins in place but does not back out, try inserting a flat-tip screwdriver blade behind the head of the bolt and gently prying away from the pan. Turn the drain plug slowly to help the remaining threads catch on the drain hole. The plug should come out.

Once the drain plug is out it is best to just replace it with a new one. To address the stripped oil drain plug hole you have a few options. You can install a

How To Fix A Stripped Oil Pan Drain Plug

The easiest answer to “how to fix stripped oil drain plugs” is to simply replace the plug with a new one. A new oil drain plug is cheap insurance against a potential oil leak. While it is entirely possible to repair screw threads, the cheap cost of a new drain plug isn’t worth gambling with your engine’s lifeblood.

Oil Pan Replacement

If all else fails then the only solution is an oil pan replacement. Depending on how your vehicle was engineered this may be an easy job requiring removing just a few oil pan bolts, or it could require removing the entire engine from the vehicle. Some newer vehicles have plastic oil pans which may not be repairable with common methods.

If none of these methods work you can always try a

      link hidden, please login to view announced the launch of a new passenger car motor oil – Red Diamond Ultimate. The company said the oil is formulated to fully meet the General Motors dexos1 Gen 3 specification among others but is also formulated to keep the oil cleaner for longer periods of time while improving performance, engine system protection, mileage and horsepower. In a news release announcing the new product, the company said Red Diamond Ultimate passenger car motor oil uses 100% Group III base oils and is infused with Hot Shot’s Secret’s proprietary FR3 Nano Technology. It is suited for both hybrid and internal combustion engines, especially small displacement, turbocharged GDI engines where it can protect against low-speed pre-ignition. The company added that Red Diamond protects against timing chain and valve wearing that often occurs and fights the formation of high temperature deposits that drain horsepower and fuel economy.
      “We’re thrilled to offer passenger car motor oil and exclusively to our dealer network,” said
      link hidden, please login to viewBrand Manager, Josh Steinmetz. “With three viscosities, we expect a lot of demand for this product given the compatibility for any vehicle where Dexos1 Gen 3 is specified. Also, it also exceeds API SM, SN and SN Plus and many of the Ford and Chrysler motor oil specs. Adding this oil to our lineup allows service centers to offer an outstanding oil to protect their customer’s vehicles.”  Red Diamond Ultimate Motor Oil is available in three viscosity weights — 0W-20, 5W-20 and 5W-30 now and in three sizes — 5-gallon, 55-gallon and 330-gallon.
