1. Oversize Drain Plug:
* Simplest Solution: This is often the easiest and most effective fix. You'll need to determine the original size of your drain plug (usually stamped on the plug itself or in your owner's manual) and then purchase an oversized drain plug. These plugs have a larger diameter thread, which engages with undamaged parts of the oil pan's threads.
* Caution: This works well if only a few threads are stripped. If significantly stripped, this might not be enough. Use a thread chaser (see below) first if this is the case.
* Availability: Widely available at auto parts stores.
2. Heli-Coil or Timesert:
* More Permanent Fix: These are threaded inserts that are installed into the stripped hole. They create new, strong threads. Heli-coils are slightly cheaper and easier to install if you have minimal experience, while Timeserts are considered slightly stronger.
* Requires a Specific Tool: You'll need a kit appropriate for the size of your drain plug and a drill to create the pilot hole.
* More Involved: This involves drilling out the stripped threads and tapping the hole to accept the insert. This method requires some mechanical aptitude and the correct tools. YouTube videos can be helpful for guidance, but be careful!
* Availability: Auto parts stores and online retailers.
3. Weld a Nut:
* For Severely Stripped Threads: If the threads are so badly damaged that an oversized plug or insert won't work, you may be able to weld a nut onto the outside of the oil pan over the stripped hole. This requires welding experience and the right welding equipment.
* Risk of Damage: Improper welding could damage the oil pan. This is the least desirable option unless you have welding expertise and are comfortable with the potential risks.
4. Oil Pan Replacement (Worst Case):
* Last Resort: If all else fails, a new oil pan may be necessary. This is the most expensive and time-consuming option.
Before You Begin ANY Repair:
* Clean the Area: Thoroughly clean the area around the drain plug to prevent debris from falling into the oil pan.
* Consult a Repair Manual: A repair manual specific to your Dodge Neon year and model will provide the correct drain plug size and torque specifications. This is crucial to avoid further damage.
Which Method Should You Choose?
* Minor Stripping: Oversized drain plug is usually sufficient.
* Moderate Stripping: Heli-coil or Timesert are good options.
* Severe Stripping: Welding a nut or replacing the oil pan may be necessary.
Recommendation: If you're not comfortable with any of these repairs, take your Neon to a qualified mechanic. Improper repair can lead to oil leaks, engine damage, and significant costs down the line. An incorrectly installed heli-coil or timesert can also be very difficult to remove, creating a bigger problem later on.
