Re: anti freeze ? to use or not to use
Daimler uses an OAT coolant in their later cars, very similar to DexCool. So does just about everyone else now. You CAN use the older formula (green) coolants so long as the system has been flushed thoroughly. Just remember that you'll need to change it every two years instead of every five.
That's really novel, since I went just the opposite direction. I changed my '94 and '86 over to DexCool about ten years ago, and have no problems as a result (so far).

Re: anti freeze ? to use or not to use
Dexcool does not cause gasket failure!
