Anyone get oil cooler lines replaced before they leaked or blew off?

[Radchad]

I’ve searched and read through all the other posts about the issue.  Truck is 2019 TB with 23000 miles

 My question is…. Has anyone got the engine oil cooler lines replaced before the dang things started leaking or worse yet blew off.????

 Are the new lines now an updated part with a better crimp???  

Obviously I may need to pay for it or do it myself because they haven’t failed to be claimed under warranty but I’m not waiting for them to blow off and damage my engine.  
 Any thoughts or experiences on this would be very much appreciated!

thank you

I have owned 8 gm trucks. 1990, 2003, 2006, 2008, 2010, 2014, 2016 and now a 2021. I live in Alberta Canada. Every winter as soon as it hits -35C the transmission cooler lines start to weap. Every single truck has had this happen and the new ones are never upgraded. I was told that the few that are covered by warranty are far cheaper than making the hoses on every truck better quality. And in warmer climates this doesn’t happen very often. 
On my third set for the 2006 ( I kept that truck for ten years) I had a hydraulic shop swap out the rubber part of the lines with steel braided line before installing them. That worked and they never leaked again. 
Yes I am a sucker for punishment ha ha. But every brand has their issues. 
They can actually “sweat” for a long time before they start to actually drip just so you know. I have never had one actually blow apart myself.

Yes, I had mine done on my 2019 at about 32,000 and almost 3yrs. old.

Is there a part number on these new cooler lines or how do we know if our trucks have the new ones already on from factory?
