Ceramic part of Spark Plug wire broke
W124, E420, 1995
I pulled the ceramic part of the spark plug wires to change the plugs. 7 of the 8 worked fine, then that one. There's nothing to grab. I fear if I pull the wire, it will come off, with the metal end of the wire stuck on the plug. How do I disconnect the cap over the plug. I'm OK with replacing the wire, but need to make sure I get the old plug out and a new one in. Thanks so much. The car is running fine now. It happens to be plug #8 |
There are special pliers for pulling caps.

That's a thought - but
Please tell me more about where to get the tool, and what it's called, to help my search. Does Phil have it?
But, will the end go deep enough to grab the metal cap? The tools I've used were the wrench type that leverages the top. Thanks |
I bought that tool from Mercedes for a W124 300E with very tight plug leads a lot of years ago. I phoned several dealers with the part number and they all had a different price. The old S124 300 has leads that can be pulled off with a finger.
Pliers part number, from the receipt: MW103 589 00 37 / 00 |

That's not the best tool for the 119 leads as it won't reach deep enough to grab the meaty part of the connector. When I have a broken one I reach for my long curved tip needle nose pliers. A simultaneous twist and pull should pop it loose.
