Is there a reason for this being unplugged?

Sorry for new thread but this is a little strange,
I know it should be connected to the plenum, but I'm presuming it's not for a reason?

Isn't that for the unused plenum/inlet manifold heater (or whatever it's called)?

It's nothing more than a bleed point to help remove air when re filling water system and bleeding
Undo it, coolant should be present instantly.





You might just see mine with a stainless Allen bolt sticking out the top.

Thank you, that's great news as the radiator is out at the moment so will be handy.
