Remote oil cooling lines
 

Remote oil cooling lines have a hard time getting to the 13 mm by oil pan

What have you tried?

When I changed them on my old Bravada, I had to jack up a bit on the engine as the engine mounts had sagged a bit over time making things tighter down there. I just used a 2x4 under the oil pan & a floor jack to lift the engine up taking some load off of the engine mounts. That and I used a shallow socket with a wobble extension and enough extensions to get out in front of the axle.

This this is the one that supports the lines with a small bracket? It is a hard one to get to and even harder to start when reinstalling. But it can be done. A ratchet box end wrench my help to get in there.

unless i'm thinking of a different bolt , I used a foot or more of extensions and went along side the engine from the front.
