Hi there i currently have 82k on my cinq sporting and was wondering should i be in need of a hg change soon? I mean the car has only ever overheated once while i had it when the rad went and even then it was just below the red line on the temp gauge. Since the new rad about 10k miles ago its been hovering around the 70c mark on the temp gauge normal driving and 90 to 100 while sat in traffic
