Anyone know a good effective way to clean sludge out of the radiator. Im not sure exactly what it is. Its coated the walls of the radiator and i can drag my finger thru it and pull out a finger full. I know my overflow bottle has oil it in so that could be it, but it just doesnt look quite like oil. It almost feels like it could be stop leak or somethin. Anyways, I want to fix whatever is causing oil to get into the coolant, and then flush/clean out the radiator/cooling system. Anyone know a good way to get the sludge out?

Mine has the same stuff. It's not oil, but it looks like oil. Run a water hose through it?

Yea, I want to upgrade the radiator, but even if I do... Im sure that crap is all over inside the water jackets and stuff... so it still needs to be cleaned out

some prestone radiator flush did the trick for me! That stuff works some magic. You can get it at walmart or any autoparts store.

you may just have to run it through twice or three times. i used in it the car i sold and it was enough to notice. cleaned it out and it worked pretty damn good!~
