If you look closely, you'll see that is a five-cylinder OM602 engine, not M104. As mentioned previously, they have very different heat loads. And, he lives in a cool climate. And, he mounted the fan to a proper shroud so it works more effectively than zip-tying a fan to a bare radiator core, with no shroud.
LOL no shroud? You don't say

I was doing some measurements on my [124] wagon with the 606 engine. I don't think I can fit any known production puller fans in there, so I'd need to spend big $ on SPAL units.
This is incorrect.

Nah, his last reply in the debate was directed at Casey, and I'll let Casey respond if he's so inclined.

A quick update:

I have done the following since my last post. I finished today:

1. Removed aux fan shroud, cleaned condenser with coil cleaner, and used a pressure washer (electric) to pressure was the ENTIRE condenser. (both sides of condenser)

2. Replaced the viscous fan clutch with a new MB OEM clutch.

3. Replaced all hoses with MB OEM hoses.

4. Flushed coolant a few terms and replaced with new Zerex G-05.

It took me longer than planned due to things like having to special order expanding rivets for the aux fan shroud...and special ordering the fasteners for the pieces that go to the left and right of the condenser....

I cranked up today, checked for leaks and seems as though all is correct. Tomorrow I will double check the transmission fluid to make sure I didn't lose any while removing the radiator.


WHAT I NOTICED when I started it back up:

1. I hear the "roar" when the engine is warm and the fan clutch is engaged. This was definitely not the case with the old clutch. Even when the engine is running at idle there is a significantly higher amount of air being moved with the new fan clutch.

2. In 95F weather I was able to let the engine idle, with the a/c on, for about 45 minus and the engine temp never got above @85C. Prior to the changes it would have been closer to 95 or greater.

Tomorrow I will drive in stop and go traffic, 90F-92F ambient temperatures....and see what happens.

So far....the results are great.

Did you get fan clutch from the dealer? Is it a Behr unit?

Based on past discussions on this forums, I was looking at a Sachs unit but they have gone out of stock with no availability date....

Too early to say I told ya so but.....I was never happy with the fact that you didn't hear the clutch fan roar. And I mentioned that some members like Steve had tried multiple fans before he got a good one. In my old TE, the one I put in I never heard roar and in traffic, it would easily kick in the AUX fans...which was not how the system used to work when newer. This new-to-me TE you can clearly hear it roar. I can also hear the clutch fan roar in my work truck. I'm not sure the best way to test them working 100%, but you should hear a roar on hot days.

Steve should remind us which one he finally settled on....I think it was Sachs?

I got the original OE MB clutch, supplied by Horton/Sachs

It's been installed for about 6 years now, without a single issue.

Keep in mind this was for my diesel, and I picked a clutch designed for the W140 S class turbodiesel.
