2004 Kia Sorento coolant leak

Hi, I really need guidance, please, I am female, 51 and can do what needs to be done but need a little guidance & it will greatly be appreciated like you don't know. Anyway I put dye in overfill tank 2 days ago because I was having to add coolant. I see the leak, plain as day and don't know name of hose or how to go about changing it, like what I should remove, the specifics and details. It is the hose that comes out of overfill tank and splits off into a "y" shape and goes into back of motor block. It is plastic, the "y" piece. Ive read online from various people how this always will eventually start leaking. One guy said he took off his windshield wiper cowl in order to get enough access to replace it and said it wasn't bad at all to do it. Kia in my area wants over $200 to change it out because its hard to get to. But I try to stay away from dealer repair places as best that I can, besides I don't have the money. I am fairly machincally inclined to take on things as being female, have it in my family, my Daddy has passed away and he always built motors and sold them and never went to any school go be taught. But with him gone, I will be doing things myself. I have a repair manual for my vehicle but not one bit of info on how to change/replace any hoses. All I need is basic instructions/illustrations on the whole process. I would be most appreciative as I've searched online for 2 days now and finally came across your site. My name is Tina and I thank you in advance. 1-864-308-7764
