1995 blaze, 2dr, auto, 4wd. At the top of the radiator drivers side. It appears to be one or both of those connections, I don't know if that is a ac line but it is bolted on to the hosing and insulated. Drips out pretty constant under pressure. Only other place it could be would be the crimp around the plastic tank. I have coolant residue there as well. Is there a seal in that area that might need replaced? Any suggestions ?
Thanks

those are the oil cooler lines, you can try removing it, and putting some plumbers tape on it

 

I determined the source it is the top of the radiator and about 1-2 inches down from the top where the metal crimp is it is hissing out of the crimp when pressure builds can that be repaired or does it have to be replaced ? If is there a seal that needs replaced as well.

 

Radiator shop,or replace it. I chose to replace mine.

 

Mine was leaking at pretty much the same place. Driver side, right on top where the side tank is crimped onto the core. I thought about a radiator shop, and I might still, since I still have the old one. But I just ended up replacing it.

 

What did the replacement cost

 

It was around $100 at rockauto.com. Autozone wanted like $160, I think.

 

its like 100 for a rad, real easy to replace. you honestly can do it on your own.
