Round Connector rear top left of engine - how to undo please?
Alfa 147 2001 ... round connector located in engine bay top rear left side of engine ... how does it unscrew / disconnect please?
On mine one half of the connector is black with a blue plastic band going about 270 degree around it and other half is green. The connector is fitted into a metal bracket which is a full 360 degree around the middle of the connector.
I've tried unscrewing one half from the other but it won't budge ... either its very tight or there is something I need to do first to 'unlock it'?
I'm assuming the blue ring thing is something to do with the unlock method?
Attached photo, but its not mine hence its a white plastic band, but just so you can see which connector I mean.
Any help / comments / method much appreciated?
