big antifreeze leak
99 5.4 auto 2wd expedition. The heater core has already been bypassed. It seems to be leaking around the rear passenger side. It will leak about a gallon idling for around 5-10 minutes. I cannot see where its leaking from. The truck runs perfectly fine. If you have any ideas please let me know.

I have a 99, 4.6l, 2wd, EB ( with rear heat) and could not add water wast enough from a water hose once... metal line going from the front to rear heater core had a 2 inch, 1/8 wide split in it... right under the tail gate..... could not see it until getting up under the truck....
haven't replaced it yet (Alabama summer... so i probably wont need heat)..... just bypassed the rear hoses.

I dont think its the freeze plug i can see the drivers side one and it looks fine but I cant see the passenger one. This has heat for the rear seats so maybe there is another heater core that I dont know about. The trucks going to my uncles shop monday because even if I find the problem I need it fixed faster then I could probably do it.
