Burping the Coolant System

Does anybody have the service manual instructions for getting trapped air out of the cooling system?

I'm going to put a "Hotlink" adapter in the coolant line, and I know some air is going to get in. Just want to know MINI's method for burping the system.

Directions per the Bentley Service Manual:

R56 Coolant System - Filling and Bleeding (without Vacuum Bleeder)
- Before filling radiator:
* switch ignition ON - do NOT start engine
* set heater temperature control to full warm
* set blower control to low
* set set heater control (if installed) to maximum

- Start engine and run at idle speed for one minute (coolant reservoir cap open). Adjust coolant level to MAX level, and close cap.
- Run engine until it reaches operating temperature.
- After engine has cooled, recheck coolant level.
- Top up so that coolant level is at MAX.
- If trapped air cannot be bled manually, pressure-bleed system using cooling system vacuum bleeder.

According to the factory manual you need to open the bleeder on the thermostat housing. See my post #5 in this thread.
