Many tool sets do not even have a 16mm or 18mm combination wrench, let alone ones that have a ratcheting box end. Mercedes never used 16mm or 18mm fasteners up until the late 1990's. Now they are everywhere - especially under the car.

This socket will help to prevent damage to your chrome 6-poing wheel bolts as shown.

This is one of the most often neglected services I see on the M272 engine. Even at 100,000 miles, you often see the tank has never been changed, and you can recognize that by looking to see if there is a factory crimp hose clamp still in place on the fluid return hose at the bottom of the tank.

The wiring plug covers must be removed with a special tool in order to install these boots. The old covers will break when you try to remove them.  We recommend you buy new wiring covers when replacing either my aftermarket custom-made silicone boots or the original rubber boots.

Did the engine just quit? Does it just not start even with prolonged cranking? What could it be? The first thing you want to determine with most older cars is whether there is spark to the plugs.

This the exact puller you will receive. Handy for small jobs.

Kent was a little skeptical when you first used this—it sounded like it would be too good to be true. The first use was getting some rusty bolts off the Garrett T3 turbine housing ( some of you know the pain there!). Well, it worked, and it worked very well.

FULL SET of correct Bosch spark plugs. These are considerably longer than the stock M113 spark plugs and should only be used in the AMG engines specified above. 16 spark plugs only. No other supplies or instructions are included. 

We modify this wrench right here in our shop. If a picture is worth a thousand words, what is a video work. Watch the following for a full explanation.

This is a perfect fit for the O.E. copper sealing ring. You only need one but we sell these as a set of two so you will have a spare.

This is where this sealing ring is located. On top of the fuel injection lift pump and at the base of the hand primer  pump:

These are the 4 long bolts that need to be removed when changing your W126 brake rod control joint on your front suspension. There are two on each side. They do not come in the repair kit so if you bolts are very rusty you might want to have these new bolts on hand before you start your repair.

I do not need to say much about this tool. Well made and well thought out. Someone who obviously was frustrated at scratching the finish on his or her alloy wheels came up with this idea. Watch the video below to see why this is now my favorite go it 17 mm lug bolt socket.

For use on 220 240D 300D 300CD 300TD 300SD 1968 to 1985. NO INSTRUCTIONS INCLUDED: The tool is meant for someone who has the factory manual or who already knows how to adjust their injection pump timing on the older diesel engines. Injection pump timing is critical for peak performance.
