HitmanX, does your M110's water pump looks like this? http://catalog.worldpac.com/mercedesshop/sophio/quote.jsp?clientid=catalog.mercedesshop&cookieid=2E70WNSVV2EV17OO4G&baseurl=http://catalog.peachparts.com/&partner=mercedesshop&year=1984&product=G3000-95807&application=000383042

Here's the real question: do you know by chance if the water pump in the link above will fit drop-in on a 617.952 engine?...and if it is a perfect fit for a 617, does the 606's fan cluch and blade fit's on this M110's water pump? I've been wishing to do this 606 fan clutch and blade upgrade for better airflow and cooling efficiency but the 617 stock set-up wouldn't allow me to....

Mine does at least, I doubt it was updated due to the PO's. I'm working on an '82 for someone that has the large water pump pulley and steel fan.

3K RPM should be 60+ MPH in top gear Are you having cooling issues?

The cooling issues that I am having is when it is 95 deg or above and I'm stuck in traffic, the gauge creeps up the the AC is not as cold when at idle and the electric aux fan can't cool off the condenser well enough at idle, but only when it's hot outside, other than that, when it's raining or night time driving, no issues at all.
That's why I want to upgrade the fan set up into a 606's to improve the cooling efficiency, plus the 11 plastic blade is lighter that the 9 aluminum blade that I have right now.

The 280S is out of town, so I can't check for you now

I'd venture to say yes it'd be the same, I know it has that style bolt pattern and the car was maintained very well... I got it cheap due to the lovely (insert sarcasm) Solex 4A1.

606/603 fan and clutch will not work with the 617 or 110 pump/fan/clutch. The 617/110 all bolt to the water pump with four bolts (a la 116/117) and the fan bolts on with four bolts.

606/603 fans bolt to the clutch with three bolts and to the pulley via one bolt in the center. 8mm I think

If you're having cooling issues, you probably need to go ahead and buy a new radiator, clean the A/C condenser VERY well, inspect water pump for corrosion, flush the system, etc. Their life in vehicles is around ten years to me. Plastic becomes brittle with age and the fins collect crap over time, this is worse when green coolant is used in them.

Does your aux fan work properly when AC is on?

My '85 (build date Oct '84), which should qualify as a "late 617," has the plastic fan. I have not measured and compared pulley sizes but believe the package came that way from the factory.

EPC shows the 110 part number for the fan blade for my VIN with the break point 50,000 VIN numbers (cars?) earlier. Before the break point, a 108 part number fan was used; I suppose that was the metal one that you are referring to.

Pretty normal of temps. I get into the 87-95C range often in hot traffic at idle, aux fan on.

For some reason, my 617 has 116 clutch and a 116 9 blade aluminum fan with a pulley diameter larger than that of an SD's, the SD's use 10x1000 alternator belts and the D's, like mune use a 10x1035 alt. belts.

I wish I can just install a 606 11 plastic blade on my existing clutch but the 606 has a 3 bolt pattern and my 116 clutch has a 4 bolt pattern, so in order for me to convert clutch into a 606 3 bolt pattern, I also need to change my water pump because the 606 clutch attaches to the water pump with a bolt at the center but the 116 clutch has 4 bolt attachment to the water pump....

Jeremy5848 · #82 07-09-2008, 08:45 PM

The 606 fan also has 9 blades, not 11; the part number is not cast (pressed, engraved, painted, embroidered) into the plastic but there was a paper label stuck to it when it arrived (from ********AZ) with the part number 602 200 04 23. I'll post pictures later this evening.

Cool! I'll just remind you to check it for me when the car comes back if you don't mind when this thread gets opened again.

My radiator is actually about 4 years old, but the AC condenser is probably from the day the car was born. I do periodical flush, I did the last one last Fall of '07 and I'm sure the water pump is still moving the water because whenever I get away out of the traffic, the temp gauge immediately goes back to 90deg normal op temp, and stays there until I get stuck in traffic again...and by the way I use the non-green stuff, Zerex G-05.

Aux fan kicks in whever the condenser gets hot and stops when I water hose it,(that's how I troubleshoot it's normal function).

There's a new version upgrade that has an 11 blade plastic fan used on 210's I believe. I'll post the link of the photo if I can find it. I think that's what is this thread for....before I hi-jacked.....

Edit: Found it! Here you go!

Does that ECE M110 pump have a threaded middle to it?

A quick check shows the M110 (USA version) pump interchanges with the 617 pump (same PN)... so it'd be safe to say the ECE M110 pump will bolt to the 617.

For sure clean the A/C condenser, pull the aux fan and use some foaming cleaner. You'll be shocked how nasty it is... plus the AC vent temps drop off quicker too.

If it matters, my SD is 10/84.

When I ordered a new plastic 606 fan blade, I assumed I'd get the latest kind. My '96 E300D also has a 9-blade fan; perhaps the change was made later in the 210 series? Do you have a part number for the 11-blade fan? I looked up the E300D Turbodiesel (606.962, 1998-99) in EPC and got a part number of 606 200 01 23 for the fan -- is that the one you mean? (The picture still shows a 9-blade fan but I know you can't depend on those drawings to depict what the part really looks like.)

The pictures attached here show the 9-blade 603 metal fan alongside the 606 plastic fan. They are identical as regards size but notice the way the 606 fan blades are unevenly spaced . . . is this to prevent sympathetic vibration or something?

After installing the new 606 fan and clutch on my 603, I checked the fan and noticed that it spins fairly freely on the clutch as expected for a cold engine. Then I started the engine and tried sticking a rolled-up newspaper into the fan blades.

No way did it want to stop; all I did was shred the newspaper. Glad I didn't try that trick with my fingers.

The 11 blade fan came on the 98-99 E300s.

Damnit why couldn't I have seen this thread before I spent a mint on a new plastic 603 fan and clutch...

We all have been in your shoes; don't be hard on yourself (blame someone else).

It's interesting that ********AZ lists the 606 parts when you ask for a fan and clutch for a 603.

it appears to have a threaded female center hub, but what I'm not sure if the 606 clutch will fit???
