Just did a coolant flush 2 weeks ago. I backflushed old coolant using my prestone tee hook up to my inlet hose. I used prestone flush solvent following instructions. Everything seemed ok for about 2 weeks. Now I see brown stuff in coolant reservoir that could be rust or some leak fix I used years ago when I have bad radiator and finally I had replaced about 3 years ago. What would be best course of action?
