Sounds like you have a rusty radiator...

Get a radiator clean/flush from a radiator specialist

btw what coolant are you using

Your Suppose to use OEM Honda Fluids only use water incase of an emergency.

So Flush it out with some Honda Anti-Freeze Coolant but also give the radiator a clean, Nulon makes a Radiator Flush & Clean just follow the directions, Hopefully this will fix your problem an many others if you have only been using water :pedosmiley2:

cylinder head or block is cracked and oil is entering ur cooling system. correct me if im wrong. soon enough ur car is gonna over heat and ur gonna lose coolant and have to refill all the time.

coolant is almost just as clear as water since coolant is 50/50 with coolant. so the brownish stuff will appear even if u had the coolant isntead of all water.

my money is on a cracked cylinder head :eh:

+1 make sure it's not oil mixed with the coolant. a cracked head gasket could also cause oil to mix into your antifreeze.
