6.3

Rubbing Hoses
FEMA
Since Ron mentioned something about this today, it came to mind as I've been meaning to ask; my front sway bar has the lower radiator hose sitting right on top of it. Is this correct? If not, please let me know how this should be positioned so I can work on it.

There's a lot that looks tight down below there - I think Ron mentioned the oil cooler line of a car he just worked on as rubbing.

Francis,
It should not touch. Are your engine mounts or radiator mounts sagged?

The radiator mounts are basically a rubber strip down each side of the radiator,undo the trans ,oil coller and radiator hoses and lift it up to check the conditon,On Robs 6.3 the rubbers weren't even there and the radiator was lying so low the fan had knocked on the shroud.There is supposed to be two rubber oval shaped rings on the top of the radiator to hold it firm, if they have broken the radiator will tend to drop and move about in the support frame. All this can cause problems like core leakage and fans going through the radiator...[:(]

The subframe mounts were replaced when I bought the car; the engine mounts were not. It sounds to me the this radiator may be the problem because the rings that are supposed to hold it at the top are not secured with the rubber as ron mentioned - can't recall if I ever had these. My mechanic in Denver may have forgotton to put them back last time. Either way, thanks! Now I know.

The rings have to go to the radiator as it is slid back down the hole ,you can't get them on if the radiator is in place,he probably put in the hole then decided it was too much effort to pull it back out...
Thec rubber strips which go each side are marked Left and Right and are available new from Mercedes.While you have the radiator out,it's a good oppurtunity to look at the engine mounts,you can see them clearly.It's also a good time to clean the fuel filter and the antifreeze device.

Ron, I am at the stage where I have to install the radiator, on reading your message it looks like I have to first hook the rings onto the hooks on the sides of the radiator bay and then pull them back over the hooks on the radiator. I tried doing it the other way, meaning installing the rings on the radiator first and then on the hooks on the sides of the bay but was not successful for some reason the radiator kept popping out of its slots.

Part numbers by chance for all these rubber pieces?

Engine mount kit was 109 586 00 22. Daimler-Benz don't sell single engine mounts, always a pair, which makes me wonder about some of the prices quoted in the posts on this topic. Radiator mounting kit was 108 586 00 50, both rubbers, both rings. Francis, I would also add that it is next to impossible to reuse the side rubbers as they have mounting lugs to hold them in place that break off when you remove them from the metal channeling.

Fracis, great job on the mag. I like your way of describing the tech stuff. Nice work bench.
Art, love that series on the "resto of the BASKET CASE" I laugh evrytime I see an article on the progress. You guys note what Art did with his fuel tank? He restored it as well.
Francis, Art and Ron have a handle on this. My best guess; the engine mounts. Happened to us after an estimated 200,000 miles on the Blue Goose. Then we put on another estimated 100,000 miles. I BLEW that engine through pure stupidity. We have now put on another new set because the engine was restored, thus you do everything else just for drill because the labor is almost zip, it's just the part price.

Dan, thanks.

After closer look at the radiator, it has looked crooked/cockeyed since last after the mechanic got thru with it - I remember looking at this and thinking is this the way they mount??? The radiator is definately in scewed, so I will remove and replace and get the new rubber. The oiler cooler line is sandwich between the sway bar and the alternator bracket, but appears to have enough slack to slide a boit to the right and get out of this sandwich.

I'll try to get to the engine mounts too, just not sure what I'll get done by June!

Undo the shroud first,and just lay it back against the engine,It does'nt come out with the radiator.

Thanks Ron, I was wondering about the shroud!

On the radiator poor mounting and alignment, I found the rubber/install kit that Art suggested - I'll get you the latest PN.

Now, isn't there supposed to be a clamp at the top of the radiator to hold the fan shroud? Mine is missing and the shroud flaps a bot - when I asked the dealer about the clamp in the picture they showed me with the radiator mount kit, there's apparently a note that says "it does not apply to this model", i.e., a 6.3.

Any clues?

It's a clip and I haven't seen too many still on the 109's but they should be there,it's a sheet metal part that fits over the radiator top tank and slips inside the shroud and there are grooves in the shroud to hold it down.I am sure that W114's have the same thing but slimmer.
There should three 10mm bolts each side to hold it place also.

Francis,
6.3's do have the clip according to the parts manual, PN 108 505 00 06. The 300's don't and the 3.5's do, but a different PN from the 6.3, 108 505 01 06.
Art
Ron B
None of my own 3.5's ever had the clip ,but i am sure i have one amongst my pile of rubb..I mean "rare and valuable spare parts"...The 3.5 one would have to slightly smaller as the groove in the shroud is smaller than the 6.3.

Searching the old data available for the lower oil cooler line that passes tightly between the alternator and the sway bar. What is the proper clearance for this line and should it be touching either part at anytime, for example when the front end is jacked up?

Just replaced the front subframe mounts so this question has re-surfaced and I have not found a definitive answer, yet.

Art Love
Francis, I still wonder about the engine mounts on that car. On #765, there is a good half an inch between the oil cooler line and the sway bar and about an inch between the alternator and the oil cooler line. I can't imagine that there is any specified clearance. No comment on your original question regarding the lower radiator hose and the sway bar because the RHD cars have a different radiator, other than to say the hose should not be on the sway bar.
Art
FEMA
Thanks Art, understood on the motor mounts because that is something I have never addressed.

I adjust that hose pipe for equal clearance between the alternator and sway bar with the car in its natural driving position. --The length of the alternator belt, integrity of engine mounts, sub frame mounts, radiator side support rubbers all influence the clearance.

Thanks much Michael, very helpful.
