    The 02-09 "How-To" and DIY Section
    I just got a new A/C system installed. New compressor, condenser, Accumulator. When I shut off the engine, after a 30 min. or so drive using the A/C. About 30 seconds later I hear a gurgling sound. At first I thought it was the Coolant Reservoir so I tried to burp the radiator with no avail...
