Replying to: ryster (Dec 27, 2008 12:19 pm) Thanks for the info . I'll give it a try but i cant help but wonder if the levels are low , where did the coolant go?. I suspected that the head gaskets were the culprit last time even though there were no signs or smell of external leaks but i'll keep in touch and let you know. Thanks again.

I am in the habit now of checking it everytime I have the hood up. I use the 50/50 pre-diluted Dex-cool offered by Prestone. I have a container of it in the garage, as well as one in the trunk of the Impala. I am just more comfortable keeping it around. My parents had a '03 Impala with the 3.8L V6. The Dex-cool in their car also just disappeared. They also had to check it regularly and kept the Prestone pre-diluted Dex-cool handy as well. From what I have read, mysterious coolant loss is not uncommon on Dex-cool vehicles.
