Most BMWs run on Timing Chain (not Timing Belt).
Search forum for tons of info on cooling system.

Your 528i does not have a timing belt, it has a timing chain and should last for the life of the engine.

You'll need two special tools (see links below) to remove the fan clutch nut.

While your doing the cooling system--change out your Vanos seals--that will bring your timing back into the spec's from the factory--do a search for Besian Systems

So I should just do the water pump and disregard changing the timing chain

are you sure your not mixing up the timing belt for the serpentine belt?

That's what I was thinking. OP probably referring to sepentine belt!
If you do the vanos, might as well do the valve cover gasket!

Good point mrpumpk1n and zybanuser.

On the E39 a water pump replacement is not sufficient to keep the car reliable. You should be looking at replacing at least the belts, radiator, hoses, expansion tanks, and a few other bits at this mileage. A cooling system overhaul!

To the OP, did you mean the belts shown in this picture (of the I6)?

Sorry but this is simply not the case, the special tools are not required.

I have removed the e39 fan clutch on 3 different cars and only use a 32mm wrench and a small hammer, both of which would not be considered special tools.

Now if you are unable for some reason to remove it then you might consider a getting/making/cobbling together a special tool i.e. "holding tool".

+1 I know you're getting a lot of do this do that, but if I were you I would do the radiator, expansion tank, and thermostat with the water pump. Serpentine belt too if you see its cracked. That's where I would start.

There are entire threads on what tools you really need for a cooling system overhaul ... plus a whole bunch of "I can't get my fan clutch nut off" help threads scattered about. Here's one, for example:
- Tools necessary for a cooling system overhaul

You're totally right that it isn't required that you have the special tools; but I have them, and, I would NEVER do the job without them. They made it sooooooooooo easy to get the fan clutch nut off (once I put them on right) that I wouldn't even consider the hammer trick.

There are MANY times where a special tool isn't required ... but the special tool makes the job sooooo much easier ... that it's worth it in the end.
- How to make your own thrust bearing tool
- How to make your own fan clutch nut tools
- How to make your own car ramps
- How to make your own subframe and differential bushings tool
- How to make your own oxygen sensor tool
- How to make your own VANOS solenoid socket tool
etc.

I am not paying a mechanic either and money is not an issue for me, if I need somthing I buy it, however there is no value in buying things I don't need.

Now do some folks need the tool, sure, I have been reading their posts for years and I have no idea why they can't get the darn fan clutch off.

I have taken the fan off 3 different E39s and each time it comes off as easy as pie without having a "special" tool. A simple carefully placed tap with a hammer on my 32mm wrench and voila done.

Not trying to nitpick but to say the special tool is required is not correct, now one might say if you experience difficulty removing the fan then you might want to consider buying the tool.

Hi XRaye39,
I'm sorry to imply the water-pump-counterhold tool was required. I should have been clearer. It's optional. A 32mm open-end wrench is required though.

As you said, some people get along just fine without the pulley counterhold tool. For example, in this thread, cn90 uses a simple screwdriver (see pic below).

Others (see this thread), say it's "100%" needed.

Either way, the OP has the information they need to make an informed decision by now.
