Replaced the clutch fan with electric fan several years ago. Replaced one controller that I damaged but other than that no problems. Have it wired so it also runs after the engine is turned off to address potential heat soak. Very worthwhile mod. FYI, there is a thread in how to section to help with install.

So you’re replacing your transmission with a used one? Are you going to rebuild the used one? What is wrong with your original?

Cant find the how-to. I'm sure it is user error...one has to be 10% smarter than the thing they are dealing with and the search function kicks my butt!

Would love to pick you brains on how you wired it, and if it works well and keeps your x cool in the summer.

Forum search engines are often a liitle lacking...

Best way to search this form (or any site....) is to use Google with the "site:" tag...

Use a search term like...

site:xoutpost.com bcredliner electric fan

First result is this...

I had a rebuilt one ready to go but the moron driving the little Toyota pickup dropped it as it was being unloaded and the shift linkage besnt to shit enough to start leaking from the connector.
I picked up a transmission from a sand dune rollover and will be test driving today, but I have my old one to rebuild it. I think I can get a good kit including solenoids with friction and steels cheap enough (400 USD or less) then we'll see....

My old one had a nuked B clutch.

I bumped the thread so you can see it.

I think all your questions are answered in the thread but if not just let me know. Fan works great. As you can see from the thread the install was many years ago. I still have the same fan. Texas summers are hot. X5 has never overheated even sitting stopped on freeway for an hour when it was 105. I have it set so it comes on just before the electric pusher fan comes on and continues to run until the engine has cooled to below the setting after it is turned off. Hope this helps.

Arranged some time. Going to pick up F10 on monday.


E53 got new coils and wipers.

I love the cool down function.

We idle our cars a couple minutes after driving to cool the turbos and more or less drop the core temp "heat soak" but I love the fan after off idea. BMW had it set up like that on early n63 but disabled in software after it was killing batteries.

Thank you, I appreciate you digging the thread up, and the write up. It’s looking more like my belt problem was caused by a crappy plastic pulley on the Bosch rebuilt alternator I got from FCP Euro. It looks to be deformed on the front lip, and is already shredding the new belt. Once I sort this out I’ll turn my attention to the tired headliner, then the fan!

As far as what I did for my X today (yesterday actually): I installed two new rear hatch bump stops. Mine were 20 years old and the rubber was long shot. The new ones have a spring function that allows them to compress a bit when the hatch closes, thereby cushioning the impact. Very nice.

I still need to come up with a solution that keeps the hatch grip from loosening up and the rubber gasket from dislodging. I installed 4 new plastic inserts to screw the torx screws into but they suck and don’t hold well over time.

BC, you know how bad I need this modification. I am just so burnt out modding this E53. I am older now, and it is just harder now to make things happen. The headers were really a shock that it happened.
