4L80E Cooler Lines
Confirmed that the radiator is leaking due to a crack in the plastic tank on the drivers side. New radiator ordered, and looking at what else I should replace as part of the job. The engine oil cool...

I always convert them to soft lines. NAPA has adapter fitting with hose barbs. I use Nitrile hose because it holds up to heat better never hardens like rubber lines.
Those lines OE-style hard are difficult to source aftermarket, GM wants way too much, and they will eventually end up in the same condition anyways. And on some of the trucks, like the TrailBlazer, you have to drop the crossmember to swap the lines.
