Blue/Brown temp sensors, fitting?

[Endless325]

Hi guys, I'm going to replace my blue/brown temp sensors, how do you fit them?

Cheers

Oh sorry, 325i!

Take the lead off, fit a socket on it and turn. If you can't get a socket on them, then a spanner.
Best to refit with a new washer. Don't overtighten.

I had trouble getting a socket over and a spanner down there so I used a spark plug spanner. Be very careful with these though as they are the wrong size and if your not careful could very easily round the faces on the temp sender.
Only alternative I could see was buy a deeper socket or remove the fuel rail

Sounds like fun, thanks fellas!

i remember removing the injector loom to get at it with a spanner
