My Ride: 330Cd and 325Ci
330d aux fan delete

Hi Guys,

Great Thread.

I am going to be upgrading the Intercooler on my 2004 Sport Coupe 330cd.

Was originally going to add some smaller electrical fans to replace the front mounted AC Aux fan that will be displaced by the larger Intercooler, but saw this thread and thought yeaaaaaaah.......perfect!

Makes perfect sense to me. My old 2001 325ci only had the engine viscous fan, so I was surprised to see the extra fan on the 330cd. It makes a racket as well, but not this time of year, its freezing.lol.

I could probably reuse the old front mounted Aux fan, by playing about and fitting it into the viscous fan housing, but I can get a 2nd hand fan for about 50.00 with the exact part number shown in the thread - 17117561757

my cars got 204,000 miles on it so far. I am looking to get at least 300k..............................anything that helps with the MPG and efficiency gets my vote!!!!!!!!!!!!!!!!!!!!
