so i have a radiator in my jeep that under the cap the coolant is green...good the bottom hose is dripping orange(i made it drip) and the resivor is a real good mud color whats the problem?
Sounds like there is a build up of corrosion inside the engine block and radiator. Most likely from running it with to much water and not enough coolant. As previously mentioned, thoroughly flush the system and refill with the correct mixture of coolant and "distilled" water. Distilled water does not have the impurities and minerals that regular tap water has and will not cause the excessive corrosion that you have now.

Its not GOOD for it, but it is a good idea to get all that crap out of there. Many many radiators will have fluid looking like that if they have not been taken care of, flushed or just had improper coolant/water mix.
Definately good to go ahead and clean it up!

NP. I still have yet to do mine along with a very long list of other things the PO neglected. Plus I have the crappy renix (closed pressure) cooling system to deal with, I want to swap the whole stupid thing out anyway.
