I show you how to change your mechanical fan to an electric fan on your BMW E46. I did this particular video on a 2002 BMW 325i but can be used for any E46. I will explain in detail in the video.

Yep, you are totally correct. The fan on my 1998 540i blew up last week. It knocked off the cooling hose going into the radiator but the worst damage was tearing up the hood liner and putting a crease in the hood.

Two questions 1-Did you notice deleting the clutch fan freed up any hp to the engine? 2-Are you sure one electric fan can cool as much as both the old clutch fan and the ax aux electric fan? I would be nervous it wouldn't cool enough with only one fan.

@shoman24v 6 лет назад

So, just to be clear, you said the auxiliary fan, which uses the same motor as the manual electric fan, only comes on when the AC is on or if engine "over heats". First off, the fan doesn't come on when the engine overheats. The fan comes on by direction of the coolant temperature on both automatic and manual cars. When the coolant temperature reaches a certain point, the fan turns on. The only difference here now is you went from a pusher fan to a puller fan. The function of the electric fan is to cool hot coolant when the car is not moving, at speed, fans will do little, if anything to cool the coolant. It seems that people get all freaked out thinking that if they remove the manual fan, all of the sudden the car is going to overheat.

How is this fan controlled? Surely you would have to put in some kind of coolant temp switch to turn it on when the temp exceeds a set point otherwise how will it come on at the right time? At least with the clutch fan you know it is always running even when its not strictly needed.

@arnolduk123 5 лет назад

I like your videos very much, but I'm not sure about what you acheived here. How do you have the aux fan connected to cool the radiator if you are using that connection to power the newly installed electric fan ? The viscous fan cools the engine as it heats up and the aux fan cools the water in the radiator. In your video you show only one fan connected and that will lead to an overheating engine when car is stationary. Also what direction is the air flow for the electric fan that you installed ? is directed at the engine (which is what is should be) or is it directed at the radiator ?

@tomcanada4047 8 лет назад

The coolant temp sensor that plugs into the radiator controls the aux fan. It will keep the coolant temp in a range so it will cycle on and off when at idle and low speeds where there is no air passing throw the radiator while driving.

@beaferoner 8 лет назад

I did this fan delete for my 2004 325i. One concern I had was that on my obdII gauge my temps would fluctuate from 96-100 and sometimes 105 but, at this point the electric fan would kick in but never stay on a constant(as you would expect the original aux fan to behave). I tested this on my friends 2005 330i ZSP and the electric fan came on around 90 and stayed on a constant lowspeed unless it reached 98 then would kick in high speed. I know the ZSP's are tuned alittle differently but I wondered how I could get my fan to behave the same. I tryed swapping the fans between the two to see if it was the fan itself but turned out the same. I've since bought an new used 2004 325ci auto and have noticed with the two fan set up my temps run a constant 95-96, and rarely peaks at 98 when in traffic at which time the aux switches on and brings it back down to 95. I would consider doing this mod again but, only if there is some way to get the electric fan to kick on at lower temps and not let the temps spike up and down. Pardon my ignorance but I am not sure if this makes any difference at all but knowing these engines sensitivity to overheating I'd rather stick to whats proven. Searched the forums but no luck on how to adjust the behavior of the electrical fan. If anyone knows how PLS PLS PLS let me know, I've been looking for some time now.

@ShopLifeTV 8 лет назад

The fans will cut on and off automatically to keep the car in a certain temp range. The fans are only really doing work when the car is standing still, otherwise airflow usually takes care of the rest when driving. As long as you have done maintenance to the cooling system, just relax and drive. Thanks for watching!

@markhammer9975 3 месяца назад

I don't know if you still have the car but somebody just told me that the reason the clutch fan is on automatic is because the extra heat created from the automatic transmission needs the constant air flow apparently.
