Whats the deal with no parts stores stocking water pumps for a duramax? Mine went bad today and after calling Auto Zone, Pep Boys, Napa, Parts America, etc.. etc.. I could not get one today The dealer had one but they wanted 3 times, (LITERALLY) for the pump then the parts stores. I ended up ordering one from Auto Zone for $98 bucks and it is suppose to be here tomorrow Everyone else said 3-4 buisness days:jerkit: I just cant believe a water pump is this hard to get or change for that matter, its a real PITA....
