    Burp the system thoroughly. Then burp the system again. Then repeat.

    lol. You have to get rid of all the air in the system if you want it to work properly.

    1. Fill
    2. Keep the cap off and turn the car on
    3. Everytime the coolant level drops add more
    4. Rinse-repeat till the fluid stops dropping.

    Watch the temp gauge while it's being done too.

    fill up the radiator all the way until it starts to come out of the filler neck, than continue filling from the surge tank... LIS-24610 Lisle 24610 Lisle Spill Free Cooling System Funnel - tooldesk.com I recently bought one of these...great investment ...If you get a stubborn air pocket i usually give it a good shot of the throttle a couple times and usually its enough to blow the air bubble out of the system... Also as mentioned watch the temp gauge..until i consider the job complete...I usually wait for the fans to cycle on and off and make sure there blowing hot air...
