bleed cooling system 997

Better than a bleed is to use an Airlift and your compressor to do a vacuum fill. Remember 50/50 mix with Porsche pink coolant and distilled water. If you've already filled it and need to bleed, lift up the little metal clip on the coolant tank and drive around gently in your neighborhood, checking it frequently. Let it cool down before opening the cap to add more. Once it seems fairly stable, check it each day for a few days.
