Bleeding cooling system on a 740 (archive)

Anyone know how you go about doing this? My car has very weak coolant to the extent that it boils when you come to a halt from a high speed run, so I need to drain it and refill. This despite having just had an inspection II, I'll be having some very short and direct words with the idiots that did the service on Monday. From now on I find the time to do as much work as I can myself, that way I get it done right.

As I can't find an obvious bleed screw, does this engine self bleed or is the bleed screw hidden under the engine cover?

The car will normally sit with the guage perfectly on the center but as soon as you stop from highway speed it starts to climb. It will start and idle with the guage on center as well, its just heat soak that causes it to go to just below the next segment and vent coolant out of the pressure release. My 735 did this once when a hose split on me and I was forced to top up with water only to get home. I'll check the fan clutch as the same time though, I presume the procedure for this is the same as for the sixes?

I'll be ordering the Bentley manual ASAP, In the meantime I would appreciate any help on this.
