However, when these lines start leaking, it can lead to serious engine issues if not addressed promptly. The oil cooler lines can be damaged for many different reasons such as age, road debris, old oil or simply becoming clogged over time The oil cooler line is a hose that connects the engine and the oil cooler, enabling lubricating oil to cycle between these two parts

It’s a part of the oil cooling system
Issues with the oil cooling line will disrupt the engine cooling process
Symptoms of a bad oil cooler line include low engine oil levels, engine oil puddling beneath your vehicle, and damaged metal lines Also, it's my understanding that the bad oil cooler pipes were limited to certain lot numbers So, toyota doesn't really know which vehicles are affected That explains why there wasn't a recall
The bottom line, i don't think they'll pay for preventative maintenance They'll only pay when the pipe fails I just noticed an oil leak on the engine oil cooler lines Looks like its been a slow leak for awhile and its been below freezing where i live the past few weeks
I know this is unfortunately typical with silverado's
I have a 2013 5.3 4x4 with 150k miles The leak is starting where the metal. The flexible hose sections of my engine oil cooler send and return lines have started leaking at the crimps holding them on the rigid lines The only official option is to replace the whole thing with new oem lines, but that involves dropping the front axle and they will likely just fail again in the same spots.
