FYI: Mechanical Fan to Electric Fan Swap

also I wasn't blaming anyone for the problem on my car.
I am hoping its an electrical malfunction and the tranny is in limp mode? If not then its simply on its way out.
I DIYed this just fine. I'm still learning and like to do my own work. I also don't have money to be pissing away at crooked mechanics. So cut me some slack!

I have got to see this; post some pics. Would be good for other members that may have this double plug!

What do you mean double plug? The plug in that goes into auxiliary fan plugs into the electric fan..so the auxiliary fan was not running was just there is What I meant.

I just want to say I did this DIY and it's amazing how quiet the car is now! worth every penny!

So I'm trying to figure out how to remove the front bumper. Looking at the Bentley manual it illustrate removing a total of 6 screws. 4 of the screws are located on each end of the bumper underneath, 2 screws on left and 2 screws on right side corner. The other 2 screws located underneath the bumper front center symetry. The manual also suggest removing fog lamps and grill next to the fog lights. Is there a video on this bumper removal. I don't see any thing in the manual about any clips that has to be remove that tends to break.

Thanks in advance for any help with this bumper removal.

Look at this as another view for 10/01 build and later, and this for up to 9/01.

Thanks a million Sansho!

This is some of the damage done by the fan blade. My Transmission Oil Cooler got destroyed. It is difficult to get the transmission's quick connect to disengage from the oil cooler. After struggling with the transmission hose with no success to get it lose, I was wondering if cutting the transmission's hose behind the quick disconnect would cause a problem. If I install the cut transmission hose onto the new oil cooler with a clamp, will it hold or will it have to much pressure and cause a major leak.

Thanks for any suggestion in advance.

Bump???

Bumping this.

Hows everyones trannys holding up?

I had a fan clutch on order, but it's been delayed. My Xi's is toast - just freewheels. Currently running my Xi with just the electric pusher.

Considering just cancelling the fan clutch order and going with with the OEM electric puller swap.

might sound crazy, but spray some wd-40 in and around that quick disconnect. i fought with my ps cooler lines when doing this repair awhile back, and after at least an hour of cussing at the car, walking away for the night after spraying wd-40 on the connection made for a 30 second disconnect the next day. if you must cut, i'd recommend buying a new line, just a little bit more piece of mind down the road. how did your hood fare during the fan explosion? i had at least one blade try and make it through my hood lol. left a nasty gash in the insulation on the underside of the hood as well as taking out most of the hoses, the radiator, and a power steering line. i also support the mech-> electric fan swap. good luck man.

First time poster here.. I'm planning to do this swap ASAP, as my mech. fan is almost at 110k miles on my 02' 330I. I've read through the post and can't see a reason not to. On the note about the tranny getting too hot after the conversion, I live on Houston and it gets hot down here.. really hot... Has anyone removed their transmission t-stat? I know we used to leave the engine t-stat out of Big-blocks back in the day to improve water flow, as our winters here last about 3 weeks and it aided greatly in cooling. Would this same principle work on the tranny as well? Becasuse of the location of the tranny t-stat it also seems it would vastly reduce the restriction on water flow it causes in the bottom of the expansion tank.

Hey guys I wanted to have feedback from people who have done the mech fan delete , any issues with auto transmission and engine temp? I have 74 k and was thinking of doing this project instead replacing fan and clutch as I fear fan will explode on me as she ages.

No issues with my transmission at all after a year and a half and 15k miles. My coolant temp is a bit high but that's because of my thermostat. Don't debate, just do it!

Thanks Solid, what's up with your thermo? Mine was replaced last year was getting stuck. Where in NYC are you? I'm in Long Island. Was originally from Queens

Mine has been in around 1.5-2 years, no issues.

Eh, not too sure. My temps are just flucuating from 93-101 for some reason.

I'm near middle village in queens.

Another question comes to mind, during summer time with the A/C on stopped at light is the airconditioning just as cold ??? I was wondering since front fan is out if cooling is affected.

If so, not noticeable.

The 5spd cars rely on just 1 Efan so I'm sure you wouldn't notice a difference as far as the ac cooling.
