W220 secondary heat exchanger part #?




Also any clues as to its dimensions and capacity?
MB are friggin useless unless you give them a VIN number to search for parts.
It might be cheaper getting this unit than having a custom one fabricated.

Use this number when ordering any bits for the s class (WDB 220 074) S class 55 AMG Kompressor.
Low Temp Radiator (Upper large one) A220 500 25 03
PM me if you need any other info.
Cheers




So its $700 here ... not cheap but custom made unit is same price but 6 week wait. Custom might be able to go a bit bigger. Will check dimensions tonight. But should be a decent fit ... and also can take car back to stock very easily.
This replicates the W220 system ...

Thanks
And thanks Finny for the part #




Finny can you give us some insight here - will fitment be an issue and are we better off going for a custom unit - or mbe modify this OEM unit?
I want this to look as OEM as possible.
Its not massive but its a decent size non the less.
BTW found it cheaper at non Benz store - roughly half price ... no surprises. Going to get it at that price ...

I kinda like the OEM piece in the car... Ill make up a template from their diagram and see how it fits ...




Seems fitting can happen withy some jiggy jiggy - but it seems the bonnet catch frame (at the rear) may need some grinding for clearance - and its possible the unit may mount onto this frame - but only once I have the unit will I be able to check the exact fit.
Hmm lets build that mock up rad then ....




I think the W220 design is setup so that this extra rad sandwiches up to the engine and A/C rads ... but sits up front. The power stearing coolers sit up front ahead of the AC/motor rads - but this is a pretty loose loop and can be manouvered to make space for this extra rad quite comfortably.
Clearance on the sides might be the only issue. The thing is the lower you go the easier the fit - but the more out of the airflow you are... so will need to see how this works.... rad has fabulous surface area and not restrictive on flow - only 21mm thick - so the motor (etc) rad should not even notice it.
It will work but it aint going to be plug and play...
