2004 kia sedona eng temp gauge goes to hot after about 10 minutes coolant level good heater blowers not getting warm

SOURCE: 2003 kia sedona over heating and no heat

Check your rear coolant lines, These lines always rust and start leaking coolant and thats why your engine over heats and you dont get any heat inside your car. This is a common problem with kia sedona that have rear A/C and Heater. There are two fixes to this problem. The first is to replace the rear heater coolant lines with the updated lines from kia. The second will be bypassing the rear coolant lines with a hose, however the rear heater will not work with this method.

removing the rear coolant lines is not that easy. The lines near the fire wall are really hard to remove. Its also much easier to replace the lines with the car on a hoist.
hope that helpfull

Hi!! check the oil if is like milk color head gaskets problems . o. if is the rear maybe the water bypass hose o this van has rear heaterinside the van . but follow the lines by the chasis on the bottom thats two thick lines about 5/8. o 3/4 . this line provide heat to the back

it is located on the drivers side underneath the van. you have to remove it from the underside of the car. you will need a 17 millimeter socket or wrench. Remove the ground cable before attempting to remove the starter.
