Don't use dex cool at all. Use the proper coolant which is a HOAT coolant.Zerex Z-05 or the Mopar stuff will work.
This. Though many don't believe it, the vast majority of the "universal" coolants are Dex-clones, meaning they are either Dex-cool or very, very close. Most of them are OAT (like Dex-cool) instead of HOAT (like G-05) and contain 2-eh, the plasticizer which caused all of the GM LIM gasket failures. The only exception is Peak Global Lifetime, which does not contain 2-eh, though it's sibling, Peak Long Life, does. Prestone AMAM is another Dex-clone. Check the MSDS under Section 2, Composition, and you'll see 2-eh: http://econtent.autozone.com:24999/znetcs/msds/en/US/391379
