Easily repair stripped or leaking threads!

Steel threads are approximately 3 times the tensile strength of aluminum.

These kits can be used in any vehicle where the size is available.

Determining Drain Plug Size and Pitch

Typically many newer vehicles have metric drain plugs. There are several ways you can measure.

You might try to bring your plug to a fastener house to measure it or ask the  dealer. Screwing a nut on the drain plug has also worked to determine the  size. If you have a  measuring instrument like a

veneer caliper you can  measure across the threads to get the diameter. But we will still need the pitch. You can try to look up your drain plug size here Drain plug application chart verify your plug size to be sure!

We also have a printable bolt chart that you could align the plug for size and thread pitch.

This page of bolts will not look like your drain plug. That's not a  problem because what we are looking at is the thread size and pitch.

Our tooling is supplied with square drives.

Normally you would use a TAP WRENCH recommended on a square or square drive sockets. If you do not have  square drive sockets you may optionally try to use 12 point sockets to drive the  squares on tools.

12 point sockets generally  will hold a square better  than a 6 sided socket.
 

EXAMPLE FOR M14x1.5 DRAIN PAN KIT 12 POINT  SOCKETS.

1) Drill square = 1/2 inch 12 point socket.

2) CounterBore square = 7/16 inch 12 point socket.

3) Tap square = 7/16 inch 12 point socket.

4) Driver tool square = 3/8 inch 12 point socket.

This is only one possible solution to turning a tool with a square drive.

Question:

A common question about repairing  drain pans on the vehicle is how do you keep chips from entering the drain pan?



Answer:

Using some general purpose grease on the drill and tap will help prevent chips from going into the drain pan. Using a low RPM or drilling by hand would further reduce the chips into the pan.

Because we are only removing the old threads with the drill, there will only be a minimal amount of material removed.



Optional tip to keep chips out of the pan would be pouring the old oil back through pan to flush any remaining chips as it drains. Then after the old oil has drained out, replace the drain plug and continue with the new oil.

Also remember the filter is there to catch any debris from normal engine wear.
