I am.

About GBP13.

The book says to drain half the coolant.  No idea why.  I changed mine during a 
speech by one of the Sport quattro owners at the Woburn event.  I just thought: 
"Hang on, this is getting a bit boring" and I happened to have bought a spare 
that morning.  So while he droned on for a bit, I whipped the old one out and 
put the new one in.  No measurable water loss.  He was still talking when I 
finished and shut the bonnet.
