Because it doesn't solve the problem. A lower temp thermostat or fans turning on earlier just means it takes slightly longer for the heat to settle at the high temps that it will settle at, but it still reached that point of overheat. It doesn't cool anything more than the existing cooling capacity.

KIS007

In S+ 225-235 normal driving. Pushing it a bit can easily go to 245. I have not crossed 250, but I have not taken it on a track. This is on 100+ ambient temp days.

you guys shouldnt worry, until mine implodes , i guess urs will be cool, the very first day i got the car, i think at 400 miles, spirited madness i got it to limp mode, but couldn't check d temp, i freaked out then, but now at 16k miles after 2 years, and countless spirited extreme madness in all temps, i can get to 270 and it runs like it needs to get to mars, if i relax, 5mins tops i get back to 230 for another bout of madness

Checked the part numbers again this morning, still not showing up. Hopefully next month...

I'll be curious how much this helps
They have increased air flow and cooler area but an important variable (perhaps most?) is the pumped oil volume/qty

2 main parameters (we can ignore oa temp since we have no control over it)
Air flow over the coolers
Oil flow thru the coolers

Wonder if the hoses and the cooler passages are bigger
This would reduce pressure drop and increase oil flow

whoover

If I'm reading this right, it's the cooler setup from the BS, which produces more power and has been tracked by many owners with no reports of overheating. It sounds like they know what they're doing.

Also, it seems to eliminate that annoying fan entirely, which is tells me that they were able to dispense with a hack because the fundamentals are right.

Ingenieur

They said it was from the F1 Safety Car
Which runs at good speed and airflow

If they know what they are doing why the problem to begin with?
And maybe it is larger flow and cross sectional area for the cooler
ie more flow

What is being done is pumping heat from the engine using the oil and conveying to the air
We are heating the air

Can't control air temp
Can't control air flow...dependent primarily on car speed
Can control oil flow with pump capacity

Increasing pumping by 20% is the same as driving 20% faster

whoover

I wasn't actually responding to your post. If I were, I'd have quoted it. That way, you can know when to start barking at what.

To hone your review, you might be interested that the cooling system is essentially unchanged from "F1 AMG Medical Car" to "DTM Safety Car" to "C63 Black Series" to Package 44O.

Same engine cooling system.

'Barking' as in a dog
Lot of passive agressive hostility nancy
Just because I've called BS on your inane technical rants no need to get huffy
Lol

Wasn't responding to yours, did I quote it?
Lol

Simmer down skippy you're getting bunged up
There is no 'us'
Stop making it personal
And I'll respond any way I like, don't need your permission

The pdf says F1 medical car
Not BS

zibby43

It's nearly identical (if not 100% identical) to the oil cooler setup on the C63 Black Series.

The F1 Safety/Medical Car used the same oil cooler setup as the Black Series.

That's why this "cooling package" is not applicable to the Black Series models.

Exactly.

Ingenieur

The product bulliten said F1 medical car???
What year was the BS introduced? 2012?
The F1 car in 2008 iirc

It won't work on pre-facelift cars either
Does that mean they share the system?

Ingenieur

Searching the part numbers looks like the coolers are from the SL65???

whoover

The front cooler is a transmission cooler and has been used on many models, including the SL65 and C63 BS, but also the SL500 beginning in 2003.

The wheel-arch cooler is an engine oil cooler and is from the SLS.
http://www.mbpartsworld.com/p/__/OIL...975001600.html

It's similar to the one used in the BS:
http://www.mbpartsworld.com/p/Merced...975001200.html

In the SLS it's one of a pair, but the left side cooler that 44O uses differs in mounting details, as far as I can tell from the diagrams, from the one used in the BS and all those other models.

whoover

All fitments of both larger wheel-arch units dispense with the fan because they're large enough to work without one. The fan is counter-productive at speed because it blocks the airstream. It was a hack necessitated by a cooler with 50% less surface area.

Yes, this info was posted on the AMG PL site a few days ago. My dealer (AMG Performance Center) has been looking into it since the beginning of the week but they have no availability & pricing info on it yet as it all has to come from Germany. IIRC from the posts on PL, AMG USA has yet to "test the solution" before they will make it available in the US. No pricing info exists yet outside of Europe where someone was quoted about 3K Euros.

Will be watching this my car seemed to suffer abit after driving to Austria in 37c temps

Bardman

If I understand correctly, this removes the oil cooling fan? If correct, and its a semi-reasonable price I will go for it. I cant stand the cooling fan when idling on a hot day (even on a cold day its a problem but my windows are down less).

I have asked my dealer for pricing and availability in Australia.

Bardman

The existance of this also explains why the C63s were so quiet at the recent AMG track day I went to. I was really surprised when we changed cars that the 507's were so quiet. I wonder what other changes they make to them for these days...

Bardman

For those interested, here are the prices for parts and install in Australia:

Panel: A2048800600 $690.00 Inc tax
Cooling System: A2045005700 $2900.00 Inc tax
$2000.00 for the install

So, approx $5.5k installed.

Looking into it further, it seems you will still get the cooling fan noise, but potentially reduced as it will be required less. For road driving, benefits seem marginal for that cost.

whoover

That's odd since the bulletin posted in this thread shows the fan's removal. Did they change the procedure?

But it does seem worthwhile only if your track the car.

Bardman

If you read through the procedure to the end it shows that you fit it back again (page 22).

whoover

I'm looking at .pdf in first post of this thread.

Page 22 shows refitting new oil cooler. I don't see the fan on that page.

Page 3 says "Elimination: Extractor fan in the wheel arch right."

Page 23 shows adding plug and seal to terminate fan power connector (presumably to avoid SAM diagnosing missing fan).

Don't mean to be argumentative but we're not reading this the same way.

Bardman

I think you are right. I was mixing up wheel arch "cooler" with wheel arch "fan". The diagrams are not really 100% clear, but the use of the word "elimination" and the termination of the fan connector do seem to confirm its gone.

The key thing being that the new cooler does not includes its own fan, and that does not appear to the case from viewing of page 16.

The confusing thing for me is, the C63BS does have a fan (from reading posts of JRCart), so it appears this solution is different (better?) than the BS solution?

rage2

C63 BS doesn't have a fan there. It's one of the things I noticed right off the bat, the lack of the cooling fan noise.

Bardman

Ok, I recall reading posts from JRcart that Weistec had made changes as to when the fan came on (ie at high speeds they made it switch off as it was actually less effective) on his BS, but he must have been talking about something else.
