I have noticed a slow leak in my radiator. It seems to be coming from just in fron of my fan. I assume the actual radiator has a small hole or something as I can not find any hoses which would allow for the coolant where it is. Any suggestions as to a possible fix or how much and where I can get a used readiator or new one. Also how the heck do I find the hole if I am going to fix it. It must be small because it only leaks when it is running and has heated up a bit.
