Im in the livery business...used to own a Suburban...know a lot of people with these vehicles. The best thing you can do is get the "Dexcool" coolant flushed and replaced with Peak Global Lifetime. Pepboys seems best equipped around here to perform these fluid flushes.
Lets say you keep cruising with Dexcool mysterious problems will happen like a leak in the radiator...a leak in the coolant reservoir...etc...
GM has been having problems with Dexcool since they started using it in 1996.

Dexcool contains an aggressive plasticizer chemical. Peak Global Lifetime is the same coolant minus that chemical.
