oil cooler lines leaking

[2010LTZ4x4]

Noticed today that the oil cooler lines seem to be leaking where they are crimped near the rad, has anyone else notice this on there GMT900? it seem to be leaking enough that it is collecting in the front splash shield under the motor.

Common problem. Time for new lines

Yep had mine replaced Dec 2011 I think it was.

Thanks for the replies, good to know that the leaky lines are common. Will have to call up my buddy at the local dealer and replace them myself.

On a 2010?

You'll have to elaborate a little more on the "2010 ?"

[white1500]

Your oil lines are leaking on a 2010 Silverado?

I know! It surprised me too, have to thank that good quality and workmanship of the company responsible of supplying those rubber lines. I could understand it if the truck was 10+yrs old but not 3.5yrs old and only 41000 miles. Oh well there covered under the extended warranty.

Mine started leaking with less miles and a few yrs ago.

Well look at the bright side, you can now get better quality lines and fluid.

The quality is no different, same lines as replacement.

This has been a problem all the way back to the 99's. You would think somebody at GM would have enough COMMON sense too correct it. Probably the same supplier making them back then as today.

Had some silver paint peeling years ago on a 1992 C1500. Took it to the dealership, they covered it no problem. BUT the guy that ran the paint shop said it was a known issue with primer & it was cheaper for GM to do the few warranty claims than change the primer supplier. Guessing the lines as well as other parts fall into that category. From reading various forums that are out there, all mfg's seem to do it as well.

Not only is this common on the GM trucks, their cars are also affected by this. I just replaced the cooler lines on my wive's 2007 Pontiac G6 GT. They were leaking from the crimp. Those lines were easy to replace, as compared to the 2007 GMC Sierra Classic I did. There is no room to work to get the lines detached from the transmission.

Yup my 2008 leaking too....just check my oil often!
