What is the name of this Line(s) on this 2018-19 Chevy Silverado 2500HD

My 2019 Chevy Silverado 2500HD 6.0L V8-Flex work truck picked up a fight with a boulder and the boulder won, surprisingly! This incident left me with a damaged radiator, transmission cooler and front bumper that all needs replacing, I was able to find the information on other parts that need replacing but I can't seem to find out what these lines are called so I can buy them. They are leaking coolant and needs replacing.  Any idea what they are called? 
They are certainly not oil cooler lines (those are behind the radiator), and they are not the auxiliary trans cooler lines, those are right on top of the transmission cooler itself, these that seats in front of the radiator are the ones I can't find out what they are.
