heater core?
About six months ago I replaced my heater core because I was getting a fluid leak on the passanger side of my cab (coolant). The leak seemed to have stopped but on my way home I noticed it again. Is there anything else that it could be? I am really trying to avoid tearing into that extremely small hole. But the last time I replaced it nothing to seemed to be wrong with the original. Any help would be great thanks.

did you use a crappy autozone core?
it is not that hard pulling out the core, what small hole do you mean?
what year truck?
all it takes is a little pinhole to leak.
you need to take it out and look at it to know what is wrong.

the autozone ones are known for failure.
at advance auto they have a ready-arire core for 21 bucks.
and 4 four season cores between 50 and 60 bucks.
i would pick one of the four season cores.
i would bet the autozone one you got was 20 bucks and it lasted 20 bucks worth.
napa is also a good place to go or the ford dealer.

Also take a look at the seal just behind the core. It keeps the core from rubbing up against the heater box, I guess. Anyway, my last heater core showed signs of rubbing (vibration?) so I replaced the beat up seal with weather seal and it's been in since Halloween.
Others here also suggested looking for a bad ground on the engine, as it causes electraliasis.

I was concerned that the rubber wouldn't take the heat from the radiator, bear in mind It hasn't been real hot lately ;-), but did drive to Phoenix and back at normal freeway speeds.

I vote for a bad ground. There should have been an instruction sheet that came with your new core telling you about this. 2 bad cores in 6 months sounds like a classic case of bad ground.
good luck Frank

I had problems with one right after another heater cores getting leaks...even original factory ones. I found that the pressure side hose fitting is designed to meter the flow, with a smaller hole or with a tube that extends into the water jacket. What would happen with mine was I'd hit higher rpm's and the high volume pump would blow the seam...too much volume for the core.

To my understanding a bad ground can thru some Chemical junk I don't understand cause your coolant to become very acidic and eat the heck out of your coolant system. I don't know if there is some kind of test for this but I have heard about it several times.
I used to work at a auto supply store and most of the heater cores we got back under warranty were usually cracked around one of the two coolant tubes because of people having a hard time getting them lined up with their home and slightly twisting one of the tubes until the solder cracks. I have to admit I am guilty of this one too.
If you are looking for a good core look for someplace that sells the Murray brand.
