my 520i se was overheating

Hi there, my 520i se was overheating but not all the time, i could drive around town and it would be fine but as soon as i reached around 60mph for a few minutes up went the temp gauge. anyway after a chat on a few forums here i changed the thermostat - which turned out to be fine, and the water pump which was broken, the originals have a plastic fly wheel on them which is renowned for breaking after 70000 miles or so, i did 135000 on mine so had some work out of it. have fitted a new one with a metal fly wheel and it is now back to its former self. thanks for all your help out there i really appreciated it. :)
