I've done it, (240D) I removed the belt driven fan and replaced it with a SPAL fan I got from Surplus Center. I have removed the A/C from my car, including the evaporator, that reduces the pressure drop thru the radiator. My intent was to see if I would improve mileage. Result - it makes absolutely no difference in fuel consumption. The system works fine, no problems with charging - probably because most of my driving is highway and the fan is not running under those conditions. You be the judge.

I'd stick with the stock 240D fan. No clutch. no sensor or relay or other potential electrical bugs. The stock 240D fans just don't have problems unless you have an accident.

Happy Motoring, Mark

UPDATE: Cleaned both sender and sensor and added additional ground to instrument panel. Gauge seems less twitchy and car runs above 80C (about 90c) in high 90's weather here in Northern Calif. Gauge was acting a little erractic with needle rising and then needle would drop quickly for no apparent reason at times, needle would act a little "twitchy" at times -might have been electrically induced. Will keep an eye out and will do a fluid change along with T-Stat change as it has been two years since last fluid service -thanks

The auxillary fan will not replace the mechanical driven fan. the aux fan is a pusher fan and is ok for what it does. a puller fan that is on the back side of the radiator is more efficient. It can pull a lot more through the rad than a pusher fan will.

Today I was at a street rod show, and here was a guy with a Bucket "T", 383 stroker with a Jimmy blower etc.... and pushing 600hp. on the back side of the radiator is this 16" electric fan . maybe I should have told him he was going to over heat his engine and all sorts of bad things were going to happen.

this something I posted on ARMY`s thread

Will I get vibration problems if I remove my cooling fan?
