Question about 2003 Kia Sedona
Rear heater tubes replaced and then flushed with a small pump to get rid of any air lock. Great flow through tubes. Blower runs fine, good cabin airflow but no heat. Tubes at core in rear are too hot to hold...ideas?

I'm going to go out on a limb and say it could be the blend door. This is a door that switches air from the A/C side of things to the heat side of things. Also if you are leaking coolant it could be the problem but I would check out the blend door and make sure that it's working correctly. Good luck and feel free to ask more question!

If the heater core is not damaged or leaking ie: if you don't see coolant on the INSIDE of your windshield or coolant on the floor inside the car then chances are you may just need to BLEED the radiator.
remove radiator cap
Fill coolant resovoir to the cold line if the engine is cold from sitting overnight.
Start engine with cap off
Wait till engine gets hot
While waiting you will see a big gurgle of air bubbles come out and the coolant level will drop
Fill the radiator with more coolant to compensate.
When the fans come on and it stops gurgling air install the radiator cap
You are done
Watch the coolant level for the next few days and top off in the resovoir as needed to keep it filled.
Your heat should be very hot now providing you installed the correct oem thermostat correctly.
Hope this helps
