I have already converted mine over to the Low Silicate kind and did away witrh the Dexcool. I highly reccomend it.

I heard that the original Dexcool was problematic and caused alot of issues in the 4.3 V6's, but it has since been reformulated. I left my original coolant in my truck for 5 years (which was less that 40K for me), and replaced it somewhere between 30 and 40K. The stuff that came out looked brand new, as did the coolant passages and radiator which I examined during my cam swap (around 37K).

Go to a parts store and get you a couple of cans of pressurized Radiator Flush and flush your Radiator out.
The just re-fill with GM Coolant part # 12378560.
It's also a lot cheaper than a $18.00 gallon of Dexcool
