Blazee is dead on. A properly balanced and maintained Dexcool based system using the Havoline "Dexcool" product will not experience much trouble. The key is VIGILANCE. There are abrasive, suspended components in the "Green" anti-freeze mix that will wear on parts much, much faster than a maintained Dexcool system. When I got my truck's Radiator, pump, hoses and other miscellany taken care of (including a leaking lower intake seal) I had completely dumped, flushed, and re-flushed the green stuff out and put Dexcool back in. She's happier than ever with a Stant cap topping off the radiator neck.
