i don't bubble when starting with the rad cap off. i don't have a muddy substance inside the rad nor the cap... its just the color of the core.

since i noticed this, i've been draining my rad weekly... the drained fluid does not contain any contaminants of any sort... its all coolant

If it is a rad core this is very harmful to radiator it could cause those small passage to block if gets harden. I would suggest to remove the radiator bring it to any radiator shop to clean it chemically.

Also the heater for your A/C under your dash ... it's all connected to the car radiator ... you must remove those contaminated water on the heather core. what's happened is, if you dont remove them and you used the heather it recirculate back to the radiator and it will contaminate the whole coolant. You need to get your local garage to check it out ... or a specialist Radiator/Heater Repair Agent.

Use 50/50 coolant and diluted water for maximum protection on your engine. Do not used plain water and change the coolant at least once a year. This problem is closed.
