I replaced the radiator approx 4 months ago now there is antifreeze leaking from somewhere and the belt is making noise. The low coolant light comes on and I add a little antifreeze and it goes out. The car does not run hot nor does the temperature gauge move to hot. Could it be my water pump?

if your radiator light is on. means your water level in the radiaror has dropped 1/3 of it's fluids. get a gallon of 50/50 antifreeze(its already premixed) just add it into the radiator. for best results start car when it's cold start adding intill full
The hoses could seem ok but have tiny cracks in them that you can't see if they were not replaced. With antifreeze the flange the hose goes on could be rusting from antifreeze and cutting the hose. Cut the end of the hose past the clamp mark if there is enough slack. and put back on. The clamp could either be too tight and cutting the hose on the metal flange or not tight enough. Squeeze the hose and if you see cracking in the hose replace it. Also, if you over fill it it could be a problem or you got a bad radiator. If it is a tiny leak in the radiator you can use radiator stop leak. http://picsbox.biz/key/radiator%20leak%20sealant. Check all the hoses and clamps and make sure the belt on the water pump is ok too. Good luck. They are a great car and worth the effort especially if you havea V6.
You need to replace the radiator,the trans.is cooled through the radiator and the antifreeze is getting into the trans.You will also need to flush all the old trans.fluid out and change the filter and fluid because they are now contaminated.
You will want to taste the leak (or get someone else to do so) and make sure it is not water. Antifreeze has a very sweet taste. You should only need one drop, and be sure to rinse your mouth out really well afterwards. Whenever a radiator is replaced, the hoses attached to it can also begin to leak, because the rubber hardens with age, and can be harder to seal again. I prefer a stainless steel band clamp, not the original equipment. A good flashlight would be a help as you look for the problem. Be sure to check the heater hoses, and the other hoses that carry coolant, as any of them could be leaking, due to "being disturbed" or due to the possible higher pressure the new radiator is giving the cooling system. Be blessed.
Check to make sure that the rubber o-ring going into the heater core located under the hood on the passenger side does not need replaced. Also check the water pump, these are both very common problems with volkswagen.
My dad used to weld the cracks with JB weld. He would make aV shape line in the crack with a grinder and fill it in. I had a 79 GMC pickup that he fixed. I sold the truck several years later and it never leaked.But then again the heads were cast iron then.If your loosing coolant . That's why your heater is not working and your car . Take it back as WORKFORIT1 suggested and tell them about it.You are the one paying for it.
It could aslo be the exausht manifold leak i just last month had to have that fixed. run your car for some time then stop and check underneath see if it is leaking towards back end of engine or if you can hear a hissing sound fron middle top of engine
