Coolant loss - watch this space

[markie_wales]

are you overfilling the reservoir  tank. the high mark is hard to see but is quite away down from the top, if it is overfilled maybe it could syphon itself out?

I can see the mark on mine OK - as you say it's probably not half way up the overflow tank, so good call to point it out, even if I'm OK.

cheers
