    How to Burp Coolant?

    I own a 2006 WRX and I'm taking my turbo out to be ported next weekend and was trying to tie up some loose ends and wanted to know the best way to burp air in the coolant system. I don't doubt some air will get into the system when I have the turbo out for the day and so..

    I've read things on the other years that I am to remove the cap on the upper resevoir and let it idle for the air to get out, but I just wanted to know if there was a concrete way to go about doing this.

    I like this one:

    The Owners Manual has all the answers but I will help you. This is the only PROPPER METHOD to add coolant and purge air from the system

    AT NO TIME OPEN THE RADIATOR CAP

    Use propper 50/50 mix for all coolant resevoirs.

    1) Fill the coolant resevoir (plastic bottle) to the fill line (put cap on)
    2) Fill the Turbo Coolant Reevoir (small metal right in front of turbo) (put cap on)
    3) Start car and turn on heater (high)
    4) Hold RPM's at 3000 for 10 minutes ( even if temp = H)
    5) Turn engine off and leave key to ACC (keep heater on)
    6) Let engine cool to "C"
    7) Repeat steps 1-6 until no coolant is required to fill resevoirs

    While replacing my turbo took 45 minutes to complete the process.

    Like I said above DO NOT open radiator cap at anytime, to do so will negate everything you are trying to do.
    Any other ways mentioned to burp the system on our cars are Shade Tree Mechanics.

    I don't like the idea of revving the engine for that long of a time... revving it for a minute at idle maybe up to 3k rpms...and I definitely don't like the idea of doing it when the car starts overheating regardless of what the owners manual says. I've never heard of it needing to be done this way. But yes you never open the radiator cap. Open the turbo cap and let the car idle refilling the coolant as necessary. It would help to get a coolant funnel also. Cycle the fans on and off every couple minutes on full hot too
