Thanks for response. Yes it is indeed a local haunt for me so more than likely to have been my car. As it happens, I was on the Gairloch road last week - not in the XJ-S though. Turns out Precision Engineering in Inverness will recore mine so that's my current plan. Just have to get it stripped out ...

Thanks. I'll look into that. As a followup - any recommendation for best antifreeze/ inhibitor?

Just had a closer look at my radiator and its not in good condition. Wondering about replacement. Jag rad is c£800. Any views on ASI PRO PERFORMANCE AA5052 aluminium radiator - or alternative suggestions?

I appreciate the great response David. Clearly a bit of work to do! Pic is at Kessock Bridge as the A9 passes Inverness onto the Black Isle. Part of but not the official route for the NC500.

Since I got the xjs 3 years ago the temp gauge sat 'mid N'. Top hose leaked last year and I replaced it and bled system. Since then on start up the water light comes on for a minute or so and goes out and stays out. Is that drawing coolant from expansion tank? Today on a dull 6° run for Drive it day...
