Refilling/bleeding procedures are on a factsheet in the members area, or try a search on "bleed and procedure" or just scroll down through techie section, it won't take long to trip over a bleed procedure.

This from a recent post is pretty useful & not as complicated as it may sound once you read it through a couple of times.

10. Set the air bleed hose downward as shown in the diagram [hooked over steering wheel]
11. Set down a container for draining coolant
12. Remove the [radiator] filler cap
13. Fill the coolant to the upper surface of the radiator
14. Attach the filler cap
15. Fill the coolant to the radiator reservoir tank flange surface

Caution
* Remove the reservoir tank cap to bleed air
* A/C Switch should be turned off

16.Start the engine and idle for approximately 10 minutes to warm up

Caution
If any of the following phenomena occurs, stop the engine to lower the water temperature as filling is incomplete. After water temperature is lowered, repeat steps from (15)
(1) Water temperature rises too high
(2) Cooling fan operates
(3) Steam comes out constantly from the air bleed hose

17. Perform the following operations after the engine is warmed up
(1) Keep the engine running at 2500rpm for 6 minutes

Warning
When checking the lower radiator hose (radiator side), be aware of burns or getting caught in the cooling fan.
(2) Check the lower radiator hose (radiator side) is warm. If it is cold, keep the engine running at 2500rpm for 3 minutes, then check again if the radiator hose is warm.
(3) Fill with coolant up to the radiator reservoir tank flange surface

Warning
When attaching the air bleed hose plug, the air bleed hose should be facing upwards as it could cause a burn if it leaks on you
(4) Attach the air bleed hose plug as shown in the diagram
(5) Attach the reservoir tank cap
(6) Keep the engine running at 2500rpm for 5 minutes
(7) Keep the engine idling for 3 minutes
(8) Keep the engine running at 2500rpm for 5 seconds then return to idling status. Repeat this 4 to 5 times.

18. Stop the engine and check the coolant level after coolant temperature has lowered.
