M113 with M112 electric fan
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.

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.

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",,!!

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 :/

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.

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

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

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

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