What I did, was cut the original hard-line about 3" from where they screw into the oil filter housing. (This end of the line usually comes right off) Then, weld on a 1/2" MIP to 3/8" FIP steel reducer. These are available at Home Depot for or any plumbing supplier for about a dollar.

Any welding place can weld these on for you if need be. The factory steel tubing is thick, so it's easy to weld. Then, add a brass 1/2" barbed x 1/2" FIP hose fitting (again, Home Depot). The last step is to get an aftermarket oil cooler with some BIG lines, and run your hoses to the front. I found a very nice cooler with specs similar to the Benz cooler on eBay for $35.

Here's what they look like when ready to add hose. I didn't want to take them off again for the photo. I chose to run my hoses up beside the inner fender. You can point your hoses in any direction you choose. Total cost with new hoses and clamps....about $60. And, ALL your parts are now new, not repaired.

Hope this helps.

your engine is yellow??????

Very Caterpillar yellow. It makes it really nice to work on. No oil leak goes un-diagnosed.

What is wrong with the stock oil cooler?

why not leave the hard lines where they are, and weld on your new ends.

weld new threaded ends on the oil cooler hard lines. then run two short hoses to the oil cooler.

what vehicle is this on?

Nothing is wrong with the stock oil cooler.

In the last couple of weeks, I had read multiple posts about folks having to replace or repair thier cooler and/or factory lines because of galling threads and siezed fittings. This method would save having to purchase the expensive Benz lines or finding a used replacement cooler.

The engine is being installed in a Toyota 4Runner.

Can you post a few shots of the whole engine? With the industrial yellow paint it sounds very interesting.

This is what I did I only replaced the hose and used the existing barbs.



I coated the degreased Barbs with Silicone Sealant as the hose ID was not a tight fit. I could not find better clamps that were small enough in time to finish the job and doubled up on the regular hose clamps.
Been in use for about 1 year now with no leaks in the hoses or where they are hooked up.

You could always cut the hoses off the stock cooler line and use the existing barbs on the end of them.

we talked about this before, but I welded on AN fittings when I did it about 5 years ago. You can find it if you search it. Then you can use basically any lines you want. I welded on the AN fittings on the oil cooler too. but I didnt cut the factory pipes, I did the AN fittings near the AC compresor.

Somebody did something like that on the old hoses on my SD, it leaked like a sieve.

Despite how it looks I did it with care and I took a lot of trouble to find hose that was made for the job.
I also found a local source of T-bolt type clams that are small enough to do the job at $7 each. But I am not removing the ones I have on now unless the cause some problem.

Also I later installed a low Oil Pressure alarm.
