So my car has been overheating alot latley.. And im starting to see coolant in my floor.. So Im thinking a cracked heater core.. But now I had heat before I pruchased a new radiator.. Then put the new one on and bleed the air out.. So what are your guys thoughts on what it could be? I have to feel the overflow resovior up every so often!!

If it's leaking onto the inside floor then it has to be the heater core but first check the hose outside by the firewall to see if you can spot any kinks.

If it's the core then you will have plenty of fun changing that cause you have to pull the dash. I had to on my EK and it was a mission cause when I pulled the dash I was like hmm might as well fix this and fix that, before I know it I was fixing everything and reorganizing the whole under dash....lol.

good luck with that i just had to replace the box that goes around the heater core because of a broken door that blocks the heater core off when the a/c is on. so i feel your pain

I suggest you find the cause for the overheating problem first.

Is it overheating while driving?

Is it overheating while idle?

Is the top hose hot? Is the bottom hose hot?

with the radiator cap off do you see any blockage in the radiator core?

How old is your coolant and how old is your thermostat?

How old is your water pump?

CRX T-Si brings up some good points to check out and possibly save you some hard work and more importantly time. your heater core leak may not be the main problem in your cooling system, a bad radiator cap not allowing your system to seal and build pressure could be the main cause of such symptoms?

good points

i would sugggest you try a leak dye and a black light to fully make sure you do not have a leak.
