Bleeding the coolant is very easy and straight forward. Lift front up, blast the heat, top off radiator, wait for bubbles to stop, and fan to come on, both hoses should be hot.

My C1 has the bleed valve. I am not much of a historian on the B series. Maybe that valve changed over the generations?

I always thought it was the earlier B series heads that had the bleed valve? My B18c1 head has it, but unsure of the year

I bought the spill free funnel to bleed it out without issues.

Heard somewhere else that OBDI integras had bleed valve and some preludes and civics do too. Mine seems to have a hole there but its not machined and drilled to where you could put a bleeder screw in. Also not sure if its even in the right position that are on 94-95 integras.
Would anyone mind posting a photo of there bleeder screw and how it connects to the head ? thanks
