These are the ones you want....

Firstly, this was my second purchase of these same tools to remove the fan clutch on my 2000 BMW 540i/6. The first set, which were chrome plated and came in a red plastic sheath, were junk. The first time I attempted to remove the fan clutch, the open end of the wrench spread open and slipped on the nut...rendering the entire set virtually unusable. With much trepidation and after reading the reviews, I ordered this set. Within 5 minutes, I had the nut broken loose with this set. You'll want to use some heavy leather gloves when applying pressure as these do have some sharp edges when you're straining to break the nut free. Other than that, this is the set you want for your tool box if you're a "weekend wrencher" like myself.

but the other device (the bar with two holes on either side) was still usable and combined with my own wrench it easily released the fan clutch nut

I bought this item for the wrong vehicle (2001 ford explorer sport trac) and it still made my life way easier. I couldn't use the wrench, but the other device (the bar with two holes on either side) was still usable and combined with my own wrench it easily released the fan clutch nut, that my last mechanic payed Superman to twist on.

This was actually pretty hard to do (bend it) because the metal is ...

Worked perfectly for my E46 fan removal. Pro tip: bend the pulley-holder tool a bit so it curves toward the radiator and gets it around the top edge of the valve cover. This was actually pretty hard to do (bend it) because the metal is so strong.

Better quality than more expensive options!

I've seen a lot of these tools online and they all have their flaws. They are either flimsy aluminum wrenches or poorly designed fitment. This is the closest thing to the actual BMW tool you can buy from the dealership and for much less! Did the job and I am glad I chose these!

Got the fan off an automatic E46 just fine. Tried the single-wrench and hammer method

Got the fan off an automatic E46 just fine. Tried the single-wrench and hammer method, but my 32mm spanner wrench was too thick to seat on the nut, so for a couple bucks, got the job done right.

'99 BMW Z3

I needed to replace the thermostat on a '99 BMW Z3. However, to get to the thermostat, you need to remove the fan. Both of these wrenches were an absolute MUST in getting the fan removed. One wrench is for the fan nut, the other wrench is to hold the spindle assembly in place and prevent it from spinning around. PS: The fan nut is reverse threaded. When facing the front of the car, you want to turn the nut counter-clockwise.

2000 BMW 323i (E46)

I bought this BMW new in 8/1999 and it currently has 173,000 miles. It still had the original water pump, thermostat, coolant hoses and expansion tank. It developed a coolant leak, so I decided to replace all of these parts while I was doing the job. The Fan Clutch had never been off before, and the ABN wrench set worked perfectly. You can see in my photos that the wrench set is still in mint condition after doing the job. I do want to mention, that I looked at other wrench sets and saw negative reviews on all of them, plus photos of broken tools. One thing that stood out in the majority of those photos, was that the "holding tool" was broken in the "wrong" direction. If you don't understand what I mean by that, maybe you should look up how to properly use an open end wrench (the fat part of the wrench should be on the back side of the direction you are turning the wrench or holding tool). Not to mention, there is no telling how many of those people were also trying to loosen the fan nut by turning it "counter clockwise", which is wrong (no fan removal set will work if you are tightening the fan nut when you really want to remove it!). I took my fan off with just normal pressure (I didn't need to hit the wrench with anything) with my two hands (turning the nut "clockwise"). The ABN Fan Clutch wrench set is worth the small price for the ease it will help you remove the fan (if you do it correctly).

it worked.

Used on 2003 BMW 530I, M54 3.0L engine. it's a bit of a trick to get the Hub Holding Tool. The trick is that the bolts on the water pump pulley are not evenly spaced- 2 "sides" are wider apart than the other two "sides". The hub holding tool fits into the wider set bolts. Also, use the end of the hub holding tool with a circle and a "notch" , not the end with 2 circles. It'll make sense when you see it.

Sturdy and strong tools, get the job done easily

The 2 pieces look sturdy and strong. I don't see how anyone using them could make a dent out of them. However, I did make a minor enhancement to it to provide even better leverage when turning the wrench. Since my BMW E46 (2002) fan bolt is rust free, with the extra leverage, all I need is a slight pull to the right (clockwise), and the bolt is loose! First pull tentative, second pull success! Feeling good. I also attached cable ties to the fan clutch, so that the tool doesn't run away from me! It did take me many attempts to proper seat the fan clutch. Note the low angle of the fan clutch (left side) when I finally got the tool to secure the nuts.

Did the job!

The product arrived on time and in perfect condition. The wrench and holder functioned as expected. These tools are designed for a specialized function and are not meant to be used with any frequency, sacrificing durability and ergonomics for an extremely low cost. If your fan clutch nut is thoroughly frozen, you will want to use heavy work gloves and/or some padding to avoid hurting your hands. Also apply some WD-40 or equivalent to the place where the nut meets the spindle from the water pump and let it sit for half an hour before trying again. The wrench is hard enough to round off the nut if it is really and truly stuck, which speaks to the quality of this tool.
