I have looked and searched for this but have not found anything. Has anybody thought about or actually removed the stock radiator fan and installed an electric unit on the under powered m110 engines? It seems there would be a small gain associated with the freeing up of some of the power the motor makes. While it wouldn't be much by itself but combine with a cold air intake, some exhaust work...blah, blah, blah. All of the mods being greater combined than the sum of their parts idea. Thoughts???

I did on my w126 diesel.I only use fan for city driving

Depends on the model year. The '73 model is an easy conversion. From '74-up you either need to use 2 small 8-10" fans, the thin version or mount it in front of the condensor.

I'v done all three. My '74 280C has the front mounted fan and my '72 250C has the rear mount.

Wouldn't just as much (if not more) energy be needed to generate the electricity for the electric fan?

Elekti As I was saying I hardly ever turn it on,just for traffic.It might use more energy,but fan was $30 at the time,fan clutch $179.

I set up a electric fan for my 230ce. So far so good. It has lasted a few arizona summers now. I used a thermostat based relay and also upgraded my alternator to power the additional load.
