pretty legit coolant leak

hey guys, so i came out from lunch today and there was a massive puddle of coolant under my truck, it was right about under where the passenger seat is, its dripping off of the heat shield over the cat and off the passenger side frame rail about even with the transmission. I also found my carpets wet with coolant, i could squeeze them and coolant would run from them. the coolant was coming from under the middle of the dash. i couldnt see any leaking coolant from the engine bay but when i climed under the truck it was leaking all over the place at a pretty steady pace. thing is that it only leaks when its cool, so when i start the truck it starts leaking and leaks for a few min till its hot. then it wont leak while im driving, but as soon as the truck turns off and starts to cool it begins to leak and leaks pretty heavily. It usually leaks about 2-3 quarts from when i turn it off to whenever i come back out and turn it back on. It does stop leaking eventually after i let it sit when its off, im not sure what makes it stop leaking however. here are some pictures of how much it leaks and from where

this is in the cab

in the cab again its down in the black area, by the vent on the floor on the right

this is the carpet pulled up on the passenger side, you can see the pool of coolant, and that whole area was wet with coolant, its not aparent but if you touched it you had a coat of coolant on your hands

this is that black plastic piece in the cab removed and you san see coolant on stuff in here too

this is about 2 min worth of leaking after shutting the truck down

passenger side wheel well looking backwards toward the cab

under the truck its hard to tell where it is leaking in this but you can see its coming from several areas. if you look at where the cross member meets the close frame rail, it looks like there is an out of focus string hanging down but that is actually a steady stream of coolant leaking

and dont worry i threw some kitty litter down there to soak up anymore leaking fluid, just had to snap some pics first

in the pictures if something looks wet, it is coolant, inside the truck and out/under

there is no coolant in the oil, i checked that too even though im mostly sure its not a head problem

SO this look like a heater core? something worse? my money is on hearter core, i think they did something wrong last time or it was defective. we will see tomorrow, i dont have time to tear it apart and do it myself.

thanks boys

Most definitely heater core.

yup it was a defective heater core, i just had it replaced about three months ago i believe, and i took it back didnt cost me a cent and they had the rugs and carpet professionally cleaned to get the oily coolant out.
