With regard to the bleeder screw, just because you can unscrew it by hand, doesn't mean you can tighten by hand (unless you want to see smoke spewing from under your hood while driving, then when you pop the hood see a bluish geyser erupting). Tighten it to oem torque spec!!!! Not that I would know from experience or anything.......
Just remember this mantra: "the torque wrench is your friend."

just get the proper Koyo cap for their radiator.
Koyo cap
"Koyo Racing 1.3 Bar Hyper Red Radiator Cap raises the cooling system pressure 1.3 bar to improve entire cooling system flow. Higher pressure cap reduces the chance of air from entering the system compared to the factory cap. It also improves the look of your engine bay."

Run car with the radiator cap off. When the fan cycles(AC off and Heater control all the way too the hottest position with fan motor off) top off with honda coolant. Then cap off. Top off overflow to max position.
After a coolant service(drain and fill). Loosen bleeder screws. Then fill with coolant until a steady stream of coolant flows from the bleeder. Make sure heater control is to the MAX heat position(this allows circulation through the heater core). Then run car and top off as necessary until the radiator fan cycles. Top off and cap the radiator. Another step that aids in this process is to take off the heater bypass hose to the throttle body(the highest point of the cooling system). Then top off coolant(car off and climate control to max heat setting). Then the rest of the process. Be patient. It takes some time for the thermostat to open, and fan to cycle. hope this helps. Basically in the trade this is called "burping" the system. All air must be purged from the system before system is capped off by the radiator cap.

I find it helpful to have the front of the car up on ramps to aid in the air bleeding process.
i recall the toyo uses nissan oem sized rad cap, someone please confirm this

wouldn't that make the radiator the highest point of the cooling system?
