I just topped of the coolant in my 98 Concours, I've owned the car for 4 weeks and this is my first North*. I did what the manual said and used a flashlight to look down in the reservior, but I noticed that the coolant had some oatmeal like particles floating around in it. Is this normal or is my coolant in need of a flush, it was just flushed about 10,000 miles ago! Thanks in advance!!
