Awesome! Ya it's on my "to do list". Makes sense you would notice a bit more pep. Less drag on the engine. I did the same mod on my old Chevy 4x4 and noticed it right away also. My fuel mileage went up about 1 mpg also.

Do it...
Im not expecting my mileage to go up as im driving her harder since the conversion, never fails to put a smile on my face...
gawd, i love my zhp... lol...

Bump. Anyone else do this mod?

Anyone else do this yet? I'm gonna pull the trigger and get it done before it gets too hot here.
Here is a link for the fan for $192 and FREE Shipping.

IDK Gary. As hot as things get there, wouldn't 2 fans be better? I once thought I'd do this, but I'm not positive I've heard anything that say absolutely this is a better thing. Until I hear more, I'll likely pass on this. I hope it goes well for you though.

From what I read all the Manuals have the single Electric Cooling Fans. BMW did away with the Mechanical fan in the E46 in 2006. Several guys on E46Fanatics have done this Mod and live in Hot & Humid climates such as Arizona, Texas and Florida. There is a guy that just posted photos of what his mechanical fan did when it came loose on his E46 just before doing this Mod. Ouch...

Cool. Let us know how it goes.

Found This...
The only big black question mark that was never understood was:
Why did the BMW Steptronic Automatic cars all come with two fans up until around 2006?
The possible answer or best anyone could come up with was the Steptronic Automatic transmission required some extra cooling hence the extra fan.
But the question still begs is why did BMW abandon the fan in 2006 with the advent of the E90 and the E60 M54 engine facelift? Did they realize the extra fan was not required?
Terraphantm a while back found some pertinent information relating the relevance of having a second fan to regulate transmission temperature since M3 cars all have the two fans.
But that discussion was not followed up because candidates doing the swap are not doing it on an M3.
As for M54 engine transmission cooling and long term effects I can't say.
Kpeng is the only member I know whom has driven with this mod in his car the longest and he has driven his car daily for a number of years in the hottest/most humid place in the USA (Florida). Another member has driven for over a year in Phoenix Arizona, the hottest/driest place in the USA, with this mod and had no issues.
Both claim that they had no issue with engine temp or tranny temp in all that time so based on their experiences I don't think it will be an issue for anyone living and driving in cooler regions.
The AC compressor is not driven by the fan but it is driven by the fan belts. In theory the AC compressor should perform slightly better because we are removing about 5+ lbs out of the belt drive system when we remove the mechanical fan.
Said and done the entire DIY is 1000000% reversible if after a couple of days you find your car is going bananas. Even if you can't return/refund your electric fan after changing your mind you can sure sell it on eBay for easily what you paid for it.
Also the DIY pays for itself when you sell your old mechanical fan and aux fan assembly. Both on their own each are easily worth $75 to $100 and carry a high demand.
