So my question, is the fitting in the cooler a serviceable fitting (IE replaceable) or do I need to source another cooler? There are two 300Ds in my PaP weight the coolers in place.

Help! I was doing a routine oil change and decided to replace my oil cooler hoses as they were leaking pretty bad. I took the two fittings off the filter housing OK, and the lower fitting on the colder no problem. The upper one though was harder to turn though and I found out why. Gotta love it when previous owner cross threads an important connection.

I took the steel fitting out of the oil filter housing on my spare engine and got a machine shop to cut the cooler threads off and tap the hole 18x1.5.
Bingo fixed. My cooler still sitting in the back seat of my toyota since I picked it up though

At the threaded fitting in the cooler comes out easily? I was afraid to try and to mess it up worse. Guess I can get just the fitting from a junkyard part then.

Ok so I got lucky as hell, it looks worse than it is. I was able to chase the threads with a thread file, and clean the stripped material from the nut. Goes on hand tight easy now. Wondering if I should use antisieze or JB weld. I know the next time that cooler line comes off that fitting probably will need replacing.

Ah, well then. Hopefully it holds together...something like that wouldn't hurt

Just get the large sized tap and die kit from Norther Tool and run a die over it. That will clean up the threads.

Any chance you know the thread size and pitch? Might be something that I look at the next oil change. I put the car back together today, I used antisieze on all the threads. Everything went on tight and no leaks! Now to figure out my weird vibration issue when/after braking. Keeping an eye on it over the next several days, put ~50 miles on it today without issue.

I don't remember, but I will try to figure it out once the heat wave breaks ... my garage is an oven right now.

The jist is that apparently Mercedes was aware of the threads stripping and created a solution. Cut off the threads and drill the hex portion of the oil cooler 21/32 for a M18 x 1.50mm tap. Tap the hole and use MBZ p/n 915013-013002 thread replacement adaptor.
I've called my dealer and the price is ~$5 each.

It's a little late now, but in trying to find material to repair a 603 oil cooler I found this gem.
