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 :?
