In this 9-minute instructional video, Kent will give you an overview of what is required to change the plugs in your ML320 and share some tips to help you avoid frustration and potential mistakes.
Plugs are one of the most neglected things we see on these old ML320s. Probably because the engine seems to run so well even when they are badly worn like you will see here. This kit is designed for the DIY mechanic. Yes you can do it yourself and save big $$$.
More often than not you will find these cracked and broken.
Since these engines run so well, some believe that the fuel injectors will last forever. If you have noticed your fuel economy is declining or your engine oil seems thin, then replace these injectors.

Kent designed this set of tools to easily pry off the C-clip holding the fluid tank onto the power steering pump, AND to put it back on after replacement. This can be nearly impossible without these tools. The clip comes off and goes back on VERY HARD.
Kent finally got so frustrated trying to get these oil caps off that he came up with this new tool he chose to call the wrist saver. Watch the video to see this unique tool in action.
This can be used on 4, 6, and 8 cylinder gas engines up around 1995. This works particularly well (using the larger socket) on the M116 and M117 V8s from 1972 to 1991. The smaller magnetic socket is a must on the deep well M103 and M103 four and six cylinder engines.
