Just purchase a good quality flush kit at the local parts store. What may have happened is someone mixed regular coolant with dexcool ( a newer GM coolant). They should never be mixed. If you have the t-stat out, remove the lower radiator hose and force water through the engine block with a garden hose. Then flush it following the directions on whatever product you get. I recommend doing the same to the radiator and the heater core.

Let me know if you have other questions.
