Brown M20 water temp sensor - What size socket?

[jpmarotta]

Anyone know what size socket you used to get your M20 brown temp sensor off the block?

Need to buy a set of deep sockets anyway, want to make sure the right size is included.

hmmm want to say either a 17 or 19, probably 19...

iirc its 19

the biggest size you need for 99% of things on the E30 is 22mm

the only things i can think of that are bigger:
- hub nuts
- fan clutch nut(socket wont work anyways)

I think I got some kind of one-off sensor, looks to be a 22 or 24mm, don't have either on hand to try out.
I guess we'll find out shortly...
