Is there a way to bypass the heater core? I've got a 2004 Dodge Dakota 3.7 l. V6 four-wheel drive manual tranny

 

Disconnect the hoses from the heater core, stick an appropriately size piece of pipe in there, and clamp it down.

 

Well, now I'm actually wondering if it is my heater car. My floorboard's wet, but when I pulled the top hose off of the heater core, coolant leaked out of it

 

Feel the stuff on the floor, does it smell sweet? Does it feel oily? That's coolant.

 

It's actually I had to replace the radiator so all that was in there was water. But that's the only thing that I could think it could be because my floorboard is literally saturated and it's on the passenger side

 

Plus
There's no longer any water in my radiator. At least I can't see any at the fill cap

 

Refill the system, then pressure test it. You can 'rent' the tool from your local big chain auto parts store. Fill the system, pressurize it, then look inside, and see if you can see where the water is coming out. If it is indeed coming from the heater box, time for a new heater core.

 

Well, I'm not able to do that. if I'm being honest, I'm stranded down here in South Miami. My truck overheated, when it did the radiator that was in it blew. so I replaced it sitting in Walmart parking lot. The way that the water could be getting inside my cab is through the heater core. That's the only means of getting in there. there's no other way for it to get to the cab inside of it anyway into my passenger floorboard

 

Not something I would be attempting in a wal-mart parking lot.... gotta pull the dash..... Bypass the heater core to get it someplace that you CAN work on it. Wal-mart will have everything you need. Including the tools.....

 

Well, technically that's not true. Mine has gotten wet after sitting in a downpour. Doesn't sound like your case though. Bypassing the core can be done anywhere quickly. Replacing the core is a whole nother ball game. To bypass, you'd pull the hoses off the firewall and hook them to something like this....

Note: They sell better ones with metal ends vs this Dorman junk, but you'd probably find the Dorman quicker, given your situation.
