Radiator leak

So something happen to my jeep and Im not quite sure. The engine starts and probably runs but the radiator will not hold fluid so I dont want to warp anything... I am trying to figure out what is wrong with it. When I pore water into my radiator then turn the engine on it just all pores out. I checked all the hoses in where I possibly could but there is no leaks... it looks like its coming from the transmission but I no its not because first that is the lowest part of the jeep and the water is clear when I put a cup of water in the radiator. I think its something with the heater core? I has to be something on the other side of the firewall... any ideas?

Trying to understand your description, I think I would take the thermostat out, run it long enough to see if it solves the problem, and put a new stat in. I'd personally start there, and the radiator itself.

Sounds like you also have a leaking heater core also.

You live in Florida. You can just take the one hose off the heater core and take the other hose and run it to the engine and bypass the heater.

The core itself is under 50 dollars. The labor time, not sure. Depends on the shop I guess. The heater core housing itself is bolted to the firewall. So you basically unbolt it from under the hood, behind the battery, and the lone fastener behind the valve cover. Then you remove the cables, ducts, etc from inside the cab, and take out the entire housing. Then, split the housing case, and replace the heater core. The core itself can be found most major parts stores. Here is my experience replacing mine. http://www.jeepforum.com/forum/f12/h...cement-870988/

Can you take pics or something? Its so hard to diagnose this issue when you say it pours out but you cant see from where...if its your radiator or hoses you would see it... approximately where is it ending up when it pours out? Mid Jeep? Front, rear, inside or out?

Sounds like the heater core to me too. I know it can get pretty cold in Orlando so I would fix it.

Down here I would not bother to fix it. I would just bypass the heater core.

Naples / Fort Myers area.
