2003 kia sorento no heat

Things to check first:

Rev. Tom, Changed thermostat and replaced coolant. I seem to get heat while driving. At stops or idle NO HEAT. Saw a lot of complaints about overflow reservoir. I?m thinking water control valve to heater core if I can find it,or a collapsing hose, last thought is bad water pump impeller.

Yes, those are the next places to go. Unless it is about time for the timing belt to be changed, you might want to hope it isn't something with the water pump. But if it is, make sure you replace the timing belt anyway.

I'm not a mechanic but all this talk about timing belts and pumps is scary. Think it through in steps, is the car overheating ? No ? You can eliminate the pump, belts , electrical system , Obama and squirrels nesting for the winter. There are two hoses that go to the car interior ( add 2 more for the ac if you have one) if they are warm when the engine is running the water is circulating through them from the engine so the water level is ok. Next is why is there no heat in the interior.?

Phil, I can?t see to feel heater hoses for warmth. I can?t find a repair manual which would help. Blend door seems to check out. Because I do get some heat while driving I?m thinking a loose W/P belt (but no squeal noise) or W/P impeller is worn and pushes more water with higher RPM. Ordered a Shop Manual from Kia still waiting. My bet is a stuck water control valve if I can get to it easy.

The water control valves are usually on the firewall ( if it has one ) my daughters Ford had heat circulating through the heater core continuously. I need to pop the hood on my Rio today before winter sets in, I'll take a look at mine.
