I need to change the thermostat in my 2000 kia sephia. How do i do it?

The thermostat is a very inexpensive part that is usually inside the radiator hose connection housing going into the engine. so just take off the (usually 2 bolts or nuts) housing and pull out the old thermostat and put in the new one. i think the water manifold is on the front of the engine, just follow the big radiator hose.
