Help: Lack of heat Options

[azian_advanced]

hey guys.. i'm trying to figure out why i don't get much heat from the heater. i'd say i'm getting half the heat than what i should be getting.

i recently replaced my thermostat and radiator cap and flushed my radiator fluid and have no leaks whatsoever inside or out.

when i warm up the car, the upper radiator hose gets hot and the lower one is sort of warm (like it should).

but the heater hoses are barely warm. i've bled the system for any air locks also. my guess is there is a clog somewhere along the heater core lines or perhaps the heater core is defective/corroded. i really hope it isn't cuz it costs $400 or more from the dealer.

what do you think the problem might be? any help would be greatly appreciated.

ok.. i just finished working on it.

i was able to squeeze my hand to where the coolant hose for the heater is located (the hose between the coolant neck from the block to the heater coolant valve). i squeezed the hose and felt like something was in it, it felt like slush/ice. so i removed that hose and drained the fluid and noticed some dirt particles that remained inside. you see, that hose is like a U shape and the bottom of the U shape is where dirt was getting collected.. this is not a good sign for the heater core and lines. now after filling up with coolant and rebleeding the lines all over again, the heater lines are now heating up like they should. yay!

right now, i'm getting sufficient heat. so i'm happy. and i don't think the heater core is that bad considering the heat i'm getting now.
