I have coolant dripping from the seem below the passenger door. Even when the truck was pointed down hill it still leaked below the door. I just flushed the coolant and double checked everything I touched and anything else. Cant find where its coming from. Its loosing a gallon every two weeks. I'm thinking the heater core but the cab dont smell and the floor isnt wet. Thats the only thing i can think off considering how far back the drip is.

Anyone have any ideas? If it is the core any instructions on how to get to it?

 

put some Bar's Leak Heavy duty sealant. works GREAT!! just put some in my radiator a week ago and it hasn't leaked yet.

 

check the hose connection by the firewall going into the heater core- sounds like it could of came loose during your flush and is dripping down the cab.

And Dont use the Leak sealant-- check for a leak first.. i would only use that stuff if its leaking out of a rad.

 

Okay so my floor is now wet. So now I know its the heater core. I checked the firewall connections and they are fine.

So... I opened the drain on the radiator so it stops leaking into my cab.

Stop leak is the worse thing i can see me putting in there. I would only do that if I was stranded somewhere.

So looks like i'm off to pull the heater core.

 

Well at least you know what the issue is now. Stop Leak and other things like it I will never put in my engine. They gum up everything.
