Temperature gauge goes up near Hot

Hose yes soft and yes have heat we haven't done the bleeder hex nut thing is that something I need too do ?

It says 18 lbs.

Water pump brand new replaced that already too.

180

Yes fan comes on I don't have #'s on my guage but I do have lines that the needle didn't go beyond half way and its going too the 3/4 line and above near hot line.

For the in the car guage its 3/4 - hot area the needle goes and it not ever been above 1/2 for the needle temp guage

She would get issues when in the near hot zone it affects the vehicle

No I don't but will see if can do that thank you for helping :)
