people have different ways of doing it, but this is how I do it.

just remember to fill the block first. i usually fill the block from the elbow just in front and below the distributor where the top radiator hose connects to. fill it up until its about to spill out. then connect it to the radiator. then fill up the radiator. then fill up the reservoir. close the radiator cap.

turn the engine on, and immediately check for any leaks or any abnormalities. if everything is normal, close the hood. it warms up the engine faster.

theres going to be a lot of air in the system because the thermostat is closed and whatever parts of the system werent filled. this is why filling the block is so important. ive seen it so many times that people only fill up the radiator then wait forever for the thermostat to open up/fans to cycle. once the radiator fans cycle, go inside and turn the blend-door to full red (hot) and turn the fan on. if your vents blow hot air, then the coolant has cycled through the heater system.

go back outside and open the hood and check for anything abnormal again. fill up the reservoir, since it'll be drained. fill it to the "full" mark. chances are if everything is functioning correctly, it'll stay at the full mark, indicating that you've refilled/bled the system. just make sure the tube inside the reservoir is connected also.

the next morning or when the motor is cool, give the system another look-over.
pull the radiator cap (make sure its cold) and fill up any coolant there if necessary. refill the reservoir to "full" if it went down.

i also highly recommend honda type2 coolant.

i've done this method at least 20 times on various customer and personal cars.

if any of you pros see any flaws, feel free to chime in
