Not the usual overheating problem

[headup240]

Alright. So I obviously had a bad heater core. The car was overheating, coolant dripping into the floor, etc. I replaced the heater core. I blew air through it to make sure it traveled through and it wasnt blocked up. I now have heat, no leaking in the floor, but still overheating and I dont know why! Someone please help.
HINTS:
1. Only one of the heater core hoses is hot. One is slightly warm and the other one is hot.
2. I've recently replaced radiator, water pump, thermostat, radiator cap and bled the cooling system.
Any help is greatly appreciated.

put your heat on full turn your car on.... Let it heat up.. then shut the car off.... and bleed the air out of your system .... you can do this by turning the rad cap a little with a rag a shit load of air with come out ...be sure you keep pressure on the cap with your hand and dont turn it all the way off...cause you have AIR IN YOUR SYSTEM HAD THE SAME PROBLEM ... keep doing this until the air doesnt come out anymore and just coolant comes out... you might have to turn the car on and heat it up a few times cause there is only so much pressure you can let out each time before there is no pressure to push the air out.......

my .2 cents

you must make sure that your radiator cap is the highest point of the cooling system for it to bleed. and make sure ur thermo opens up too

When you filled it up did you unscrew the bleeder valve enough to the point where coolant would come out?

If you haven't that means there definitely is air still inside as that is the highest point the coolant goes through

Also,

For bleeding your system, I HIGHLY recommend using the yellow bucket/funnel with cork deal

It works very well and you can keep the coolant you don't use

I hope its one of the things the others posted, if not it may be a blown head gasket. You mentioned overheating, sometimes overheating will cause a blown headgasket.

Bleed the system, more than likely your problem here. Also, do you have an e-fan setup or a clutch fan?
