I think you need to go take a closer look, your radiator has two coolant hoses, one bottom, one top, they're about 50mm or so in diameter, the other two hoses at the bottom, the little ones, which I think are what you're describing, connect to the automatic transmission "heat exchanger" in the radiator bottom tank, and those should have automatic transmission fluid flowing through them.

You might want to check & see what it is that is actually leaking, coolant or ATF, and where it's leaking from, coolant leaking past the AT fittings would suggest the bottom tank is compromised, pray that you don't have coolant leaking in to the ATF (or vice versa or you're going to be looking for a new transmission soon

 

So it is clearly coolant (green and smells like coolant). Doesn't feel greasy/slimy/whatever-the-english-word-that-describes-ATF. Transmission works fine as well. I didn't realize those hoses are for ATF. I guess I will take it apart and see. If the bottom tank is compromised, is it a radiator replacement?

 

That is, as I said earlier, a transmission "heat exchanger" line. In theory, you might be able to seal it by snugging down on the nut that holds the fitting to the plastic tank, but, I can see the plastic tank is discolored towards the top of the picture, that's not a good sign, I'd suggest you replace that radiator sooner rather than later - that tank can fail without warning.

 

Thats just the light playing tricks. It is black throughout without discoloration. My biggest issue right now is finding a parts supplier in Canada (BC) for the rad. If you happen to be in the Great White North, any suggestions?

 

Make sure you have a radiator handy before you try to touch that sealing nut. I'll bet even money the tank cracks as soon as you try. They will fail without warning, when they do, you dump all the coolant and its at the very least head gaskets and a resurface. They overheat that quick.
