It should have an overflow jug. That is where you fill it.

As tuff4x4 mentioned, the overflow jug on my wife's 2004 Kia Sorento is on the passenger side, up near the windshield.

Thank you both. We have another vehicle that said not to add fluids there but since there seems to be no other place we will do that. Thank you. Do you know how to tell if more antifreeze is needed? Denise

There should be a low mark and a full mark when hot on the side of the jug.

I took an unsharpened pencil and used that as my "dip stick" for the over-flow jug. As Tuff4x4 mentioned, there are marks for Low / Full on the outside of the jug, but my the one in my wife's car is opaque and difficult to see how much fluid is in there when parked in the garage. So, I used the pencil and marked where the fluid level was (before adding any more), where "Low" looked to be and where "Full" appeared to be. By no means exact, but closer than I was getting just by eyeballing via the opaque outside of the jug. If you're losing a lot of fluid and have puddles under your car, you may want your mechanic (or the Kia dealer) to test the system for leaks. Ours ended up being separate issues with the A/C & heater units that caused the radiator fluid leaks. Good luck :)

Thank you so much. Would you happen to know how to drain the radiator to put fresh water and antifreeze back in?

There should be a drain/petcock on the bottom of the radiator usually on the drivers side facing the engine.
