Coolant Temp Sensor Nut Size

[philipCriswell]

I am trying to replace the EFI coolant temp sending unit under the intake manifold. Does anyone know what size the nut is on the housing? It's fairly large, maybe 24 or 26MM?

Thanks.

I think its like a 17mm or 19 mm. I dont recall it being that ridiculously big.

I just pulled the alternator off to the side and I can see it in there, just can't quite get to it with a wrench. I am trying to get the size and get a crows foot or something in there.

It's bigger than that for sure. The one on the front of the engine is smaller, I think a 17 or so. But the one under the intake manifold has a big ass nut on it for some reason. I have metric wrenches up to 22 and it is bigger than that.
