well when my Vectra went it had no smoke at all idling, was a very hard rough spot when accelerating (once past it went fine as normal) - temp gauge shot to 100c so thought best pull over, flipped bonnet, looked like water bottle had had an orgasm, refilled, started, and watched as my Vectra 2.0 GLS did it's impression of an extremely powerful smoke machine at a rave oO
lol... me and cars...
