I think the Williams has a water leak.
I had to top the coolant up yesterday, took it to work, flushed the system out, refilled it today. Bled up all ok - as you'd expect.
Drove home 22 miles and coolant is at minimum. Will top it up and take it back to work.
Is there any common pipes / areas for leaking. There is a coolant stain around the top hose on the rad - but it never looks damp.
Any help / experience / guidance would be appreciated.
