Have some problems Options

Okay, so now with this Koyo radiator, I have noticed a few things. There was this brass colored pipe that went from stock radiator to something. This new radiator seems to have less things than my stock on did, like an insert for this brass pipe thingie. I had some antifreeze coming out of the radiator from near the cap, but I must have did something right, because it all stopped. Now I have a problem with my cooling fans, as they make this loud and horrible noise when they turn on. It is really embarrassing and I dunno what it could be. Maybe the motor? It sounds like a motor or like those machines that put air in your tires for $.50 as the gas station. When the fans stop, it has that same loud noise, but then it winds down. That's one of my questions.

The other question is how do I get my heater to work? I was having trouble getting it to work before and wasn't sure if it happened when they replaced my radiator hose and thermostat or after the clutch (going back as far as 3-5 months). I thought it was because I had a crack in my radiator up top, that maybe I wasn't able to feel heat from the heater. Now with a new aluminum radiator, I drove it around, hard on the freeway and still no heat. There is no difference from running the cold air and the heater, yet the ac appears to work (I think).
