everything is in the details.............

2003 Kia rio regular, not a cinco. Motor leaks. how much will that cost me at mechanic? and could "I" do something to fix it cheap. I put water in Radiator....travel about 998miles going. 8 miles coming back, on same trip. takes me a total of 20minutes-go7come back. a quarter of the radiator water is gone. The gauge stays in the middle now. before- It use to go to "H" within the 8mile trip, so I would travel back and it will be at "H' gauge.someone checked it. told me--its a leak in the motor. I just bought the car(Its not even 2weeks old).


NOW WHAT?????????????
