Just bought this car -Kia Optima 2004- and cannot find the way to drain the water from the radiator. Also, cannot find books or manuals for my car yet.
So, how do you drain the cooling system, besides removing one of the water hoses?.
TIA

There should be a radiator drain near the bottom of the radiator tank. If not remove the lower radiator hose. Here is a diagram to help you. Check out the images (below). Let us know if you need anything else.

Look for a radiator drain near the bottom of the radiator tank. If no drain is present, remove the lower radiator hose to drain the cooling system.
