Not to long ago I noticed my car was starting to get close to over heating then twice in one week the light came on and I shut it down right there.

So far I know my cooling fan motor is shot and my radiator and condensor has a ton of dirt in them (external), its like someone took it drifting at the beach. I put in a 160* stat and that helped some and I know the fan motor is a big part of the problem. I used a water hose and got a lot of the loose stuff out but thats about it. Is there something I can make or buy to get the rest of it out with out having to remover the radiator?
