The engine is a 2.0L petrol turbo (197 bhp) ,with chain driven cams ( current type ). The vehicle is 2009MY and the Water Pump was original it had only done 68,000 miles.
The plastic water pump housing had broken along the top edge, allowing the seal between cylinder block and pump to blow out and empty the coolant,
Hope this is enough information
Kind regards
