Oil cooler line leaking again

[Poobear]

Oil cooler lines leaking. They were replaced little over a year ago before i bought my Jimmy. Is this a recurring problem with gm oil cooler lines?

How did they replace them, and with what parts?

 

I did the engine oil, transmission fluid and power steering lines on my truck several years ago and they aren't leaking for me (acdelco for engine and transmission, whatever brand from napa for the PS lines).

In a word, yes.  For the last 35 years, I've never seen a GM oil cooler line, transmission cooler line, or power steering hose that didn't leak sooner or later.  Our 2009 Silverado is on it's 3rd set of oil cooler lines and is starting to 'sweat' at the crimps again.  I've been told that NAPA parts may be better than the AC Delco/GM replacements, or that getting custom made hoses at a hydraulic shop would be the best.
