cooling system

i belive my heater core cloged, i do not have any water in the oil, and nothing is coming out of the exsost other moisture, but it keeps on over heating. what could be wrong, is it a cloged heater core, or is my head gasket fried, please, help me out guys, i just want my 80 celica gt back

??

Hard to diagnose over the internet.

Have you tried draining the coolant system? Flush and refill.

Do you have any coolant???

i have coolent, but it keeps burning off, and i have no heat, i lost all heat when the car started to overheat

overheat like how long?

hopefully you don't have a blown head gasket. :(

it takes it about 35 minutes to over heat, and i am almost positive that my head gasket didnt go, its not blowing smoke out from anywhere., but if it did go, anyone know where i can get a cheep 20R, or 22R?

so, it's overheated several times?!

By overheat, I mean the needle in the red.

That obviously isn't good. Warping head, etc...
