A bottle brush works great . You can buy them at the Wal Market or just about any grocery store .

Ive been gone a while and boy did this topic grow,Opatience is someone who works in a garage and that makes him feel like the ASE certified mechanic of the world, well if that floats his boat.
as for the radiator overflow?/washer fluid resvoir, i had to clean mine out, and i got it pretty clean without removing the top, over the coolant part of the resivoir, there is a hole, about 1/2" in diameter, that looks as if there should be a cap on it, ive seen other peoples fords with this hole with out a cap, is the hole supposed to be uncovered or am i missing the cap?

 

You're missing the cap. There should be one pretty much like the washer fluid cap...If you still have that one.

 

Yeah but ive seen other trucks, simular to mine, that have no cap over the hole, and the hole is much smaller than the washer fluid hole.
