What to Do When the Oil Pan Drain Plug Threads Are Stripped?

[LeoAnn]

If the threads of the oil pan drain plug are stripped, you can re-tap the threads, replace it with a slightly larger screw, or install a threaded insert. Here are several methods to address the issue: 1. Replace the Screw: Re-tap the oil pan drain plug hole or replace it with a slightly larger screw. 2. Seal with High-Temperature Sealant: Use a high-temperature sealant to seal the plug permanently and switch to an oil extractor for future oil changes. 3. Threaded Insert: There is a product called a "threaded insert," which is a mature solution for repairing stripped threads, including those on oil pan drain plugs. Repair shops that frequently encounter stripped oil pan drain plugs may consider keeping these inserts in stock.
