What engine is this ? Gen I, II, III or LS ? If you are sure it is coolant, have you pressurized the system yet? Nothing cleans like hot antifreeze! Pull the plugs and look for some clean or wet plugs if you don't have a system pressure tester. Give us more info on the engine.

Call Autozone & ask if they have a coolant system pressure tester in their tool rental program. Usually pay a fee up front but when you return it you get your $ back. Pressurize your cooling system and see if it will hold pressure for 5 minutes. This is a basic test but a good place to start.
