Nearly cooked the Mondeo earlier when I got stuck in a horrible jam in Newport for about an hour and didn't notice the temp was in the red until we got moving and she felt a bit sluggish!
Luckily I was just about to rejoin the motorway, so whacked the heaters on full blast and cruised at about 60 in top gear until the temp came down.
It seems OK, but will have to check the fans.
