TW> GM used the "Dex-Cool" system in several vehicles between 1995 and   
    TW> 2004, including the Pontiac Aztek, Grand Am and Grand Prix.   
      
   they also used it in the bonnivilles... i know this because we have several of   
   them as transportation vehicles and all of them have had problems related to   
   the cooling system... these days, we purchase the "orange" coolant that "is   
   good for all color cooling systems"...   
      
   it was a real Royal PITA until we figured out the problem was the coolant   
   fluid :?
