    911 Problems Forum
    :help I am new to this forum and GMC's. I bought a 2007, 3500 classic with 67K miles on it in May from a Texas dealer. 4 days ago I noticed coolant dripping - from radiator area. I can't pinpoint the leak. Looks like my 100K GM warranty may not cover this. Any info on whether this is a trend...
