Normally you only need to bleed these when you are doing a flush or drain the entire system. If that is the case here, there are air bleeders on top of the thermostat housing and over the water pump. With an empty system you open the bleeders about two or three turns, then start filling the system. As coolant reaches the bleeders you close them and keep filling the system.
Be careful as the bleeder valves are very soft brass and easy to damage.
