Oil Cooler Lines 2004 GMC Sierra 2500

[Shellygirl]

Recently installed some new oil cooler lines on my 2004 gmc sierra 2500 pick up truck and they leak. I am pretty sure that I installed them correctly. They are leaking on the block.

I have not messed with oil cooler lines in quite some time. Did you remove any old seals or gaskets at the block prior to installing new seals or gaskets?

Get a new gasket and try to torque the two bolts down evenly, I think the torque spec is 105 inch pound.

Make sure the adapter block isn't leaking also.
