Has anyone tried to retrofit the m113 with the electric fan the m112 comes with?

Can't imagine it being too difficult and an electric fan won't suck down power when in use.

Can you possibly elaborate as to why you would you want to do that!!!

The fan is driven by a pulley. When the clutch engages, it robs power from the motor..

Idea of an electric fan is to remove the fan clutch and have an electric motor spin up the radiator fan and this would relieve the motor of it's duty.

If I remember correctly, I saw an E55 with an electric fan a few years ago, try searching on the AMG forum.







Good luck

Good ques., i hate the clutch idea, and always ask myself many times why MB equipped an Electric fan to the 4/6 cyl.

rather than 8 cyl...!??!

is that has any related to the RPM rotational mass...??

I think I read somewhere that the clutched fan drew one tenth of a HP---so for me this is a WGAF situation---you loose that much with under inflated tires plus the ware and that is a GAF situation!!

Agree with you,

i tried driving the car without fan & fan clutch, its more fun, i feel i didn't lose drive ability, especially after 4000 RPM...!!

Glad that I'm not the only one that wishes for an electric radiator fan.

The idea of using the M112 fan and shroud is to have a direct swap...hopefully!

Our blocks have the same thermostats it's just getting a switch that'll do switching on and off. Going off the top radiator hose is a possibility BUT even that is beyond what I'd like to do.

I might purchase a E320 radiator fan with the shroud and see how hard it would be to do...for all I know, there wont be enough room.

If anyone has any other ideas, please chime in.

It's a great idea to get that damn clutch-off,

i think W210 OEM Electric fan comes with "430W", while W203 4cyl. & 6cyl. is "600W", and 8cyl. "850W",,!!

Thanks ZAYED for info!

I'm overseas but I was able to buy the electric radiator fan. Once I get back, I'll slowly start to tinker away at how to do this efficiently. One thing I did notice is that we (with M113) don't have much space to work with :/

Any Time,,

definitely worth to try....

The M112 electric fan is not simply switched on and off - in fact it is rarely completely off. It is a variable speed fan controlled by a module fitted in the left front wheel well. Fan speed is based on load determined by several inputs to the controller/module. The twin fans fitted in front of the A/C condenser are also eliminated. On high speed the electric fan is quite noisy. It also draws a fairly high electric load which translates into extra load on the alternator, so what HP gain can be achieved is questionable.

SerbNerd

The idea is to retrofit parts from the V6 model to get OEM hookups and not tap into a radiator hose like aftermarket setups.

I agree that there will be no HP gains in going this route because energy is energy but drawing 30A from the alternator shouldn't be too big of a deal. Noise also isn't too big of an issue.

I assume that having electric fans will feel like they aren't robbing as much power from the motor because it's not being run off the belt. I'd also like to be able to run the fans at full speed at a stand still just like we can run our AC fans on full.

Honestly, if we're all driving at highway speeds and not in stop/go traffic then we can run without a fan clutch :p

Since I'm overseas, I can only talk at the moment so there won't be much updates but I'll start to experiment within a month or two...or may do a swap to the big boy M113

Old thread i know... But anyway...

Where do you think the electrical power comes from to drive the electric fan?

SerbNerd

Off the alternator being run off the main crank. Positives are that by switching off the electric fan you decrease the load put on the engine by the alternator.

W202AMG

Yep, but if the fan is running because youre not moving fast, itll put just as much drag on the accessory drive.

A fan clutch has better cooling potential but an electric fan offers attractive features. Most newer vehicles use electric fans and so does the Mercedes M112.

A quick google search nets these points:

-Consistent cooling—they maintain their airflow at all times
Reduced water pump wear
-Versatility—they can be mounted in front of or behind the radiator
-Multiple sizes and configurations—they can be found in diameters up to 20 inches and are available with single- and dual-fan setups
-Fitment—some electric fans have thin profiles so they can fit where belt-driven sometimes can’t
-Control—some electric fans have an adjustable thermostat while others allow you to operate your fan from your driver’s seat

Yeah mate i know the benefits, but the effort involved and loss of originality on a rare car kills it for me.

SerbNerd

Not sure I'd call non-AMG w210 rare but I understand. It is a hassle and we know Mercedes tested these machines from absolute zero to plasma temps.

The only bothersome thing is that a garbage truck and my W210 sound similar until I fly by

W202AMG

Not so much a W210 but mine is a W202, there was only 60 C43s came to Australia.

SerbNerd

Ahh well sir, you have a rare car! I salute you in keeping such a car alive in Australia!

Believe it or not, Purdue University has 2 C43s and 1 C36 only a few houses apart

W202AMG

Ive only ever seen 2 C36s on the road here, and never seen another C43
