Changing coolant... DexCool or???
Someone posted a VERY interesting article in a thread I started on LS1Tech, Page 2. It's a very good read.

From what I've heard Prestone Extended Life is supposedly the same formulation as DexCool. The colors are just added. Otherwise all the coolants would be more or less clear.
I MIGHT change coolant... If I do I'll probably go with Zerex G-05 coolant. I think Ford, Mercedes-Benz and a few other companies use it without problems and their engines aluminum/iron/whatever like ours. I think the main thing is change it often...
