Luney Oil Pan Drain Plug Repair Kit 114PC – Metric M13–M22 Thread Repair with Hardened Steel Taps & Plugs

Keep oil changes straightforward and prevent leaks by rethreading stripped or worn oil pan, transmission, and differential drain holes.

What exactly comes in the kit and why does it matter?

The Luney kit includes 114 pieces arranged to cover the most common metric oil drain plug sizes. Having matching taps, plugs, and washers lets you rethread and reseal the same drain opening in a single repair operation, reducing downtime and the need for multiple trips to the parts store.

• 6 taps: M13×1.25, M13×1.5, M15×1.5, M17×1.5, M20×1.5, M22×1.5
• 36 replacement oil pan plugs: six of each metric size

• Packaged with anti-rust oil and separate bags for preservation

How do I use the tools to repair a stripped oil drain thread?

Start by selecting the tap size that matches the original thread pitch and diameter. Carefully thread the tap into the damaged hole to cut new threads, remove swarf as you go, then install the matching replacement plug and washer for a reliable seal.

• Choose the correct metric tap for diameter and pitch
• Use steady pressure and back off periodically to clear metal chips
• Fit the supplied drain plug and washer to confirm a tight, leak-free fit
• Apply thread sealant if preferred for added oil-tight protection

Will this set fit my vehicle's oil pan drain or differential?

The range of metric sizes covers most passenger cars and light trucks with low-profile oil pans and common transmission/differential drains. If your vehicle uses metric drain threads between M13 and M22 with the specified pitches, this kit is likely compatible.

• Includes M13, M15, M17, M20, and M22 metric sizes
• Designed for passenger vehicles and light trucks' oil, transmission and differential drains
• Useful for aftermarket low-profile pans and service repair situations
• Check your vehicle manual or measure existing plug to confirm fit

What are the materials and durability features of the rethreading tools?

The taps and replacement plugs are made from hardened steel for wear resistance and long service life. After forming, taps receive a protective anti-rust coating and are individually bagged to reduce corrosion during storage, making them suitable for workshop environments.

• High-hardness steel construction for longevity
• Anti-rust oil applied after manufacturing and separate packaging
• Sharp thread geometry for consistent, clean cuts and easy swarf removal
• Smooth-bottom plug design for secure grip and installation
