I accidentally kinked one of my oil cooler lines (don't ask :cool:) and I'm looking to replace them. Only the "Inlet" line is available and Mopar discontinued the other cooler line. I'd rather create my own oil cooler lines and be done with it. So I was able to remove the oil cooler lines but what a PITA to get the lines through the gap between the frame and radiator core support. Incredibly tight fit and I had to carefully use a crowbar to open up that gap with damaging the frame or core support.

This is a shot from the oil cooler. I plan on slightly enlarging the hole I cut out for my brake cooling duct to allow the routing of both oil cooler lines. The gap where the stock lines are routed is ridiculously tight and I understand now why the lines rub together. Even though my lines didn't leak I did find that the lines were rubbing together, starting to splinter and it was a matter of time before they leaked.

I decided to create my own lines as opposed to looking for used and non-existent aftermarket replacements. The costs of doing this project which includes everything needed (listed below) was below the cost of two brand-new OEM lines (if they were still being made).

Making the actual lines was the easy part. Connecting them was just a very painful experience due to the my large hands and tight fit nature around the oil filter adapter. But it's done.

First, here's the view from the front of the oil cooler. I used one 90 degree AN fitting for the inlet line and a 45 degree fitting for the outlet line. (AeroQuip -10AN). I had to remove the bumper reinforcement, air dam and panel that was blocking me from being able to access oil cooler connections with my wrenches at the oil cooler. Made the job of tightening the fittings at this connection much, much easier. I ended up routing the new lines through the same location where the stock lines ran.

This view is from the side directly behind the oil cooler connection. They route through the same opening as the stock lines did.

From the engine bay. It's still a tight fit between the frame and radiator support. I will protect these lines with rubber tubing as I did with the OEM lines as well as secure them away from rubbing against the frame.

Connection at the oil filter adapter. Just a very tight and difficult area to work with when tightening the fittings. Even with protective tape, AN wrenches, etc. I scratched up the nice AN fittings. I'm not losing sleep over the scratches on these fittings that but I know some of you are fainting over the scratches. :cool:

In cases like this, pictures don't say a hundred words.

I am sure as you say, it was a PITA, where as the pictures make it look easy.

Good for you and your efforts ! Wish I was inclined as some of you here.

Do yourself a favor, take a piece of 5/8th heater hose about 6" long cut down one side and where the braded hoses touch each other, place the H/hose between them and wire tie them. That will keep them from rubbing through! :drive:

Nice work! I just did mine last night and wondering if I connected the hoses correctly. Does the line off the bottom of the cooler go to the fitting directly above the oil filter?
