Thanks for the replies, according to factory the cam belt should be changed every 5 years or 90 - 100,000 kms , so time wise its due this year. I pulled the cover off as suggested and everything looks clean , belt looks fine, tension ok. Just working my way through all the general service items, replacing all fluids, filters and plugs all genuine parts of course. The belt will be next on the list hopefully within the next couple of weeks, belt, tensioners, idlers , water pump and thermostat etc.
