Photo Diy- Spark Plug Change.
As promised, I did the plugs today.
It is a bit of a chore, but no real tricks involved. Just lots-o-tight spaces.
You will need a few special tools, including a slim profile spark plug socket.
I used a Stahlwille socket#51, a 16mm socket with rubber insert.
A T27 Torx bit and a Low Range torque wrench (for the Torx screws- 8Nm),
and a regular range torque wrench for the Spark Plugs (28 Nm).
Another tool that made the job easy, was MB part# 110 589 01 01 00, aka
Hazet # 2771. Lucky me, it happens to be the same tool used to adjust the valves on the Old 280GE. Two for the price of one! You can actually find those
floating around on Ebay for cheap. It is worth every penny for this job. You use the wrench to pry the spark wire off the plug.
Other helpful items were 3" and 5" extensions, and a U-Joint.
In all, it took around 3 hours. A preatty straight forward procedure.
Although the coils and plug/block areas ARE marked with A & B, I was paranoid, and just did one plug/plug wire at a time, JUST IN CASE!
PLEASE NOTE!! AFTER RECHECKING THE COMPANY'S WEBSITE, THE SPARK PLUGS **DO NOT NEED!!** ANTI-SEIZE PASTE!!!
