Yes, it failed.
But only on the offside indicators being too slow and the O/S/F wheel bearing being "noisy".
Not too bad really - cleaning up the earths should sort out the indicators (he says, hopefully) whilst a new wheel bearing shouldn't be too much of a problem.
In addition I have to fit the new electric fan thermostat thingy - I have bought one recommended by the famous Dave Sideways so let's hope it lives up to it's billing.
It should certainly stop the water loss by the side of the other one in the top hose.
