I got to thinking about coolant types and requirements, and decided to research a little bit. What I found online was that Prestone makes a coolant that fits the bill. Its called Prestone Extended Life Antifreeze/Coolant 150/5.
It's an ethylene glycol base, and silicate, phosphate, borate, and nitrite free.
I will be changing out the Dex cool in the Chevy Uplander as well with the same.





I changed out my coolant yesterday, flushing with six gallons of distilled water, and topping off with a seventh after adding the anti-freeze. Not sure the finished mix ratio but it took the whole gallon of Prestone plus the water.

As a side note, for those sitting on old coolant, afraid to harm the environment. http://www.cdphe.state.co.us/hm/hhw/...antifreeze.htm
I researched this and found that 95% of all treatment facilities are able to do this. dilute and flush down the toilet. Flush a few times to get it on its way and out of the pipes.
