Default Refilling coolant, any particular proceedure to get out the air in the line?

On my wrx it is common to fill the reservior and then "burp" the lines. The Audi has a completely different setup, one bottle (not 2), is it as simple as fill and go? Reason being that the lower lines were removed for an oil cooler install and all coolant is now in a bucket. Thanks in advance.

Default There is a bleeder to the right of the throttle body, but since you didn't pull the WP or thermostat

you can just fill and idle and fill, check levels the next day and top off if needed.

Make sure you got the "cirrus" clips back on the radiator hoses :P

Default also, give it some revs

add coolant while idling, keep the cap off, rev the engine a bit, level will go down, add coolant again... repeat until coolant level in the radiator remains the same

Default I pulled off part number 3 in the attached pic, is that the thermostat for coolant?
