Trans cooling line rubbing against idler pulley

[Bill55AZ]

2002 Silverado, 5.3L engine, and my son, with the young ears, says something is rubbing under the hood. I just had it in for new oil pan gaskets and looks like the mechanic either forgot to mount the cooling lines back properly or the front bracket just broke off. Anyway, one of the cooling lines was rubbing against an idler pulley.

Looks to be very close in there, it wouldn't take much for this to happen on its own. Eventually, it would have worn thru and could have been a fast leak. Next time you guys are under your trucks, take at look at where your cooling lines are running and make sure the brackets are holding them where they are supposed to be.
