If the fan is running too much be careful about just replacing the radiator with anything oversized.

The fan should not run at all if you're moving at any decent speed.

Your old radiator may be clogged up to the point where some of it's cooling capacity is not there. This can make the fan run more and more unitil it can't cool the engine. In colder weather you should easily feel a difference between top and bottom hoses, indicating the radiator is removing enough heat for the engine to run cool enough.

If you decide to replace the radiator understand it COULD hurt your mileage. I would just put in what it called for as you are going to get more distance for the same fuel it stands to reason you need less cooling system, thus less heat escaping to the atmosphere.

I would remove some grille block most of my cooling fans rarely run unless I'm stuck in traffic crawling along and it's hot outside.
