This is a picture of the hoses and the cooler before I started on it.
It is obvious the lines are seeping oil. The one on the left has damage from road debris. Both lines are seeping oil and they get replaced. If you look at the seal around the cooler it is rotted out and it gets replaced as well. Those old hoses are now off, and the cooler is out. I will R&R the cooler seal and the hoses.
That area has a hard life. All the road debris and lot of water from driving in the rain. Since my car has windshield wipers I do drive it on the road and sometimes it rains.
