All things considered you should just replace the thing. I'm doing mine Wednesday, and during the process I'm flushing out the whole coolant system with vinegar. I'd just replace the heater core though.

u should find out what hose is the intake hose and what hose comes out, then get a garden hose and pull off both hoses and stick it in the outgoin so it pushes back out thro the intake hose but make sure the intake hose is pointed towards the ground, but your best bet would be to go to orileys or something and get a coolant flusher u hook up a garden hose and water and then do it but u can just use a garden hose to it will work

A flush probably won't fix your problem. I sent you a PM.
