need help asap

Ok so I just did some work on my truck, replace the Y pipe in the back what a nightmare that was, any how I removed the radiator to replace the water pump and thermostat, and when I removed them the trans cooler lines were rusted up pretty good, ok so I just put the radiator back in and now I have a leak from the passenger side trans cooler line on the radiator, Now a black o ring did drop out and I put it back into the nipple coming out of the radiator but I still have a leak, any ideas this radiator is a year old i sure hope I dont need a new one.

when I move the trans cooler line up and down the coolant pours out, this oring ws inside the radiator not sure if its replaceable

[sinner6.0L]

the trans line should be unscrewed and the fitting left in the rad. trans line is 5/8" the fitting is around 1 inch

[littlebigrig6.0]

ye that fitting in the radiator is around one inch, I had to remove both of them to unscrew the trans lines, the driverside is fine no leaks its the pass side im having problems with is their any way to fix this with out buying another new radiator

[sinner6.0L]

Not sure, I've never taken one of those fittings out

Ya don't unscrew the fittings out of the radiator if you did most likley your screwed and will have to either replace it or have a shop pull the lower tank and reset the fittings. I learned the hard way, cost me a new radiator, the trans coolin lines unsnap and they be a major ***** to unsnap with out a special little tool. I made my own after messing up my fittings and finding out how they come apart. Good luck to you. Oh the little o ring goes on the tube that unsnaps and slips out.

fixed new fittings and cranked them down good no more leaks
