Edit: I just looked up the part # on the EPC for the oil filter nipples and tangofox was correct. The part # is exactly the same as for the repair "screwed nipple" for the oil cooler!!

jbaj007,

Thanks for that information. It could easily lead to thousands of dollars saved by forum participants. In a way, using the oil filter housing nipples on the oil cooler is an obvious no-brainer. But I would not have thought of it in a million years. Although it may just reposition the dissimilar metal corrosion problem. But for the oil cooler, two lives might be enough.

As for corrosion at the joint, I'm sure its a combination of many years with heat and the dissimilar metals. Whatever happens, it sure locks the threads - wow I had a huge open end wrench and I really leaned into it and then when it came free I saw the results!

Threads stripped clean away!

When I replaced hoses recently (on my '87 300Dt) I used a glob of Alunox on the threads. Its the joint material developed for aluminum wiring in commercial bldgs (rememebr when aluminum wiring was outlawed in home construction after so many homes burned up!?) As if I might have to change the new OE hoses I installed in another 19 years or so, heck I'll be 80 years YO then and I doubt that I'll have the car or even be working on it, but if its still running the next guy will find it easy to remove the hoses from the nipples, that I sure of!

I suppose I should renew the oil cooler hoses while the oil filter housing is off. The local MB dealer wants $180 for the two hoses. Anyone know a better source for genuine MB hoses? (I don't want an aftermarket version.)

*************** at about $50 each, OE. I used some and they worked just fine.

How long have the hoses been in service? I want some that will be still working fine 20 years from now.

Look for the tiny tri-star on the crimps of a OE hose. It should have a two-row crimp. I'll bet ******** AZ is selling the WorldPac hoses - the ones that have been known to blow at the single crimp. If its not layered hose I don;t use it. Even the dealer shipped the shop a WorldPac hose, so beware!
I'm a believer in saving money but only where its less important, things like oil cooler hoses have grave consequences if they fail.

My thoughts, exactly. That's why I specified genuine MB hoses. Thanks for confirming that decision.

I'm going to try this to see if it can fix my weeping lower oil cooler line fitting.

I was concerned about not being able to get all the cuttings from the threading operation out of the cooler before reattaching. I checked the oil circuit diagram and find that oil from the cooler flows immediately to the filter, so I'm somewhat relieved.

Any opinions? Other than reasonable diligence, do I need to do anything special to clean the cooler prior to installing?

Thanks,
Bob

Ones I have from ********az are OE, from Continental, not "WorldPac". They are double crimped. I can't warranty them for 20 years, but I've got some that are a year and a half old that are doing fine.

Double crimped is what is right, WorldPac sells some that are single crimped and not layered hose. ANd BTW ********Az is a great place to get MB parts!

My car still has its original hoses. The supply line is double crimped. The return line is not.
