I can't 100% recall as I put it back onto the stuck boot panicking thinking I'd just broken my perfectly good ignition coil.RUM4MO wrote: ↑Thu Feb 02, 2023 8:39 pm How is the coil pack extension fixed to the coil pack, I'm asking as I have bought a spare coil just to have in the car, and have been tempted to separate the two parts to see how/why they can end up coming apart, the rubber extension is available as a spare part I've noticed?
But from what I can remember there was an electrode that came from the coil itself and contacted a spring in the boot. The boot itself had a circular rubber top that the spring protruded out from with a lip that the coil just pushed into. There didn't seem to be much keeping them together.
Which I guess explains why they're bolted to the cylinder head to keep them in place and intact. To be fair to it though it did take some force to separate
To stop this from happening again I now pull the coil up slightly with the tool then grip the boot between the index and middle finger on my left hand and pull it all out together in one big sort of fist of ignition coil and tool.
Although with the coils on the 1.2 ea211 being rotated and set back a little it could be a bit awkward to get 2 hands in but that's just from looking as I've only changed the plugs on my 1.8 ea888.
