I need to replace the radiator, but can't figure out how to get the upper connection on the passenger side off. I tried to wiggle it out (assuming it is an O-ring connection) but it won't come off. I don't want to break anything.

Can someone chime in how it comes off?

Thanks.

that is the tranny cooler line, are you sure its not threaded it, if it isnt then just pull harder

No, its a hard line, and has that flange on it that bolts it to the radiator. Just like the 2 lines coming out of the trans. So I am 90% it is just an O-ring seal, held in place by the flange bolt. But wanted to make sure I am not braking anything (and the hose/tube must be reused for the new radiator0.

I will spray a little PB Blaster on and wiggle/hubble/wedge a bit harder.

Is this antifreeze or tranny fluid going through here?? recently found a leak on bottom side leaking from shiny circle metal connector. I didn't know how it was attached though. should i be worried that my bottom connection is dripping slow for a month now.. ive noticed coolant go low a few times.

Took quite a bit of force (slotted screwdriver, wedged in) plus wiggling to get it out. O ring seat corroded is what made it a bit harder.
