'85 Civic coolant bleeder valve

OK, i just replaced my water pump, t-stat, timing belt, and adjusted the valves. I've read and been told about a bleeder valve to use to help bleed air out of the coolant system. I've thoroughly examined the t-stat housing and don't see a damn thing resemebling a bleeder valve. Did some of these motors come without them? Is is possibly located somewhere else?

It is on the housing onthe head not on the thermostat housing. Looks just like a brake bleeder.

Thank you very much, I found it.
