How do you change the radiator

I just recently purchased this car and it runs awesome. Well, upon driving it one day, I started smelling something sweet so I knew immediately it was antifreeze. My husband checked the radiator and sure enough, it had a major problem. The previous owner had put some sort of gunk on it to stop a leak. Now, I have the radiator and my husband is afraid of tearing up the fog lights and headlights to replace it because you have to take the whole front off apparently. Any tips or tricks on making this any easier process?
