Fan removal.

Is there a way to take the fan and shroud off without the holder? I have a 32mm wrench but no holder. Can it be done?

I'm assuming you mean the fan/fan clutch assembly and not the fan shroud. I tried using a strap wrench and screwed my water pump pulley up. Lesson here, use the right tools for the job. The one shown in the ebay link is a good deal.

I used a screw driver between 2 bolts and it was a success. Just be careful because you can mess up your pulley.

I did the same as Sawhead.

Wedge a narrow screwdriver against two bolt heads, push counter clockwise while turning the bolt clockwise.
Funny thing though, I can't seem to get mine off either. Haven't even started the engine after the rebuild so I don't understand why its so difficult.
I gave up on it yesterday and took a break from the car all together so go luck with your removal.

Since you all on the topic of fan removal can some pics be taken so the newbies can understand what you all talking about and see first hand how to do it..

Here ya go Jamafia,

Here is a pitcure of the tools, the screwed up pulley and the old and new pulley.

To get an idea of how it works, look at the picture of the screwed up pulley. You can see the large 32mm bolt on the shaft of the water pump and you can see the 4 small bolts holding the pulley on. Imagine using the hold down tool (the one with the holes and carved out sections at each end) to put over two of the bolts on the water pump pulley. Then you put the 32 mm wrench on the nut on the shaft of the water pump.

To loosen the nut, you must turn it in a CLOCKWISE direction since it has reversed threads. If the fan/fan clutch has not been removed in a long time, this can take some strength or a good rap of a hammer on the wrench.

lso, I have seen the screw driver method used before, but I would recommend loosening the four 10 mm bolts that hold the pulley on prior to using the screw driver. This way, if you happen to monkey the bolt heads up, you can remove them by hand.

I made my own tools to remove BMW fan clutch one to hold the bolts at the narrow position and another to remove the fan. They work wonders and these tools go about all over town everytime a friend needs to work on their car .

for some reason i only have this one pic of the pulley wrench. this one holds the pulley. they are thin so that you can remove the fan without taking the air box off or anything no hoses nothing works great on the z3,e36,e39,e34,e30 i'll to to get a pic of them tomorrow from all angles. They look cheap but work wonders the other one is a thinner version of this one.

Air will pop it right off, I use an air chisel and one quick rap and it spins right off. It may leave a little nick in the nut but I just reuse the same spot.

I researched this and put all the results into the VERY best of E39 Links, but this one thread below will have more than you can find on your own and should be as applicable to the E34 is it is on the the E39:

Hello -

I have come across different methods of removing the Fan Clutch. Some have used the screw driver method where you jam something like a large flat head in between the bolts to stop the water pump pulley from turning. I tried this while testing the idea one and broke the pulley. Mine was not metal, but rather a ceramic like alloy / material.

I would recommend getting the right tool for the job. A number of vendors provide Clutch Removal Tools - you would do wisely to get one slim enough to fit into that space. There are some GM tools that an do the job too.

The nut on the clutch is counter intuitive or reverse threaded as it is self locking based on the pulley rotation.

I am not 100% sure on this, but I thought the E34 and E39 use different clutches and pulleys - M60B40 vs. M62 engines. Where there is a difference is usually the nut size of the cluth itself and then the distance between the bolts on the pulley - that is often why you see pulleys tools with either an extended hole on one end or double sided tools with different spacing at each end.

Cheers,

Michael
