Ok, I have 2001 Kia Sportage 4WD with 107K on it. Ok during the winter months I had a squealing noise only when i accelarated over 70 miles an hour or climbing up a ramp onto a highway. I had belts changed and still makes the noise, so now it's summer, I decided after 2 months of not driving it, started it up and was going down the street last week and the temp button almost hit H, and then the fan kicked in. (i didn't have the AC running on it either), and then continued to ride it for a week. Today I went about 30 miles or so and ran the air conditioner on the highway and fan kicked in the whole time. Got into town and then the temp button went up to H again. I turned off the air and the temp still woulnd't come down. So I shut the car off and let it sit. About 15 min I started it up and them temp went back down and I heard the fan. As I got into more city traffic (no a/c running) it started again, but then when I took off it kicked in. It continued to do this the whole time (i then started to smell antifreeze)but when it got just before H, it kicked in again. I tried to find the overflow tank (i think it's the little one connected with 2 hoses on each side) and coudln't see anything it, antifreeze was a little low, but no spills or leaks found on ground. Any help would be great? Is it the fan (cuz it was squealing and still does vaguely) or the switch or anything else I might be missing?

I do all my own work, I have replaced the head gasket, o3 sensors, brakes and little stuff, but need help since I am a single mom with little money.

Thank you

You can private me also if you would like. I need to get this fixed ASAP since I drive 52 miles 1 way to a job and rely on this not breaking down on the highway!
