I don't think I've ever checked this
, so got a bit of a shock yesterday on picking Herman up from his biennial gearbox service at Mackies last night to see a Big Red Warning Light in the display.
Popped the bonnet (or rather John @ Mackies did...) to find the coolant level was way below minimum. Very weird - no issues on the last two long distance drives (back from MJs and then up here to Mackies), so I read this thread with interest and will be keeping an eye on it on the drive south later this morning...
