Get a flush done to clean out the bits of rust/dirt you get in the cooling system.

Possible head gasket leak. Engine oil will make the glycol get brown and crappy looking. Keep checking the engine oil level , it will be going down if it is leaking into the cooling system. Overheating a car can sometimes cause this. Pressure testing cooling system should help confirm problem.

This type of leak will really change glycol color; not just small specs. Small chunks of solids could be from old rad core.

flush the system out at least twice then check it after a few miles, its likely rust buildup and old coolant that hardened

flush cooling system? you say to fill out all the colant of the radiator and fill with new?

Use radiator flush chemicals to do so until water runs out clear. The fill out with new 50/50 coolant and if it turns brown again you have internal engine problems. Head gasket dead or damaged water pasages on block or head. Check oil levels like 2001VE said.
