Where is the expansion valve located on the 2004 KIA Sedona

Next I replaced the FRONT expansion valve. My original post above needs to be deleted but I see no means to do so in thei forum. The FRONT expansion valve in in the engine cpmpartment mounted to the firewall. It has 3 bolts, each different one is a stud one a ling bolt and one a torx screw. You will need to unbolt the enging ground strap and remove the 10mm nut holding the wiring harness. You will also need to unbolt one pair of freon line connections in each direction, one about 6 inches forward of the expansion valve and one pair under the vehicle. If you do not unfasten these you will not be able to remove the expansion valve from the stud and will have excess difficulty trying to reinstall the bolts. Just clean and reoil each o ring seat when you do so and never touch the valve seal areas without gloves and fresh refrigerant oil, PAG 46 for this vehicle. Once replaced and reassembles, run a vacuum for minimum of 1/2 hour, a full hour preferred. The system takes 35.4 ounces of R134a freon. So three 12 ounce bottles will fill the system. But you likely lost some oil when you opened some of the line connections, so best to add an half an oil charge cannister, first before refillig with freon. While the system will fill itself from the pressurized bottles with correct low side connector, A set of A/C service gauges will tell you much more about what you are doing if you know or learn how to use them.

Hopefully you don't have to replace the interior evaporator coil or heater coil as to do so requires total removal of the dashboard and entier supporting framewofk beneath. Its a major task best left to well trained mechanics. The air bags will need to be removed, so first disconnect the negative battey terminal and wait a few mnutes before proceding. The entire front dash has to be removed, no shortcuts. Despite that once the glove boxes are removed you can see the FRONT HVAC box, and it does come apart 3 ways, there is no way to remove the part even if you could remove the rear screws and clips. The Kia dealers want $550 labor plus parts to do this task.
