No, I cannot really see any evidence, that's the problem.
I got the "Coolant Low" message on Friday after about 3 miles, and found the coolant tank nearly empty. Topped it up and drove home - half down by then.
I've not touched it until today, and it's down just a little. The only witness marks I've seen are some red antifreeze on the apron under the engine, just belowthe aux. belt area, but no wetness near the water pump at all.
I've ordered some UV tracer dye and hope that will identify the leak; it seems that the engine needs to be running and the system under pressure, but I couldn't do that over the weekend as my neighbour has a young child feeling poorly and the engine noise wouldn't have been welcome.
