I am a new member of the forum and was hoping for some info. My Barina was purchased new in 2009 (3 door auto 1.6). It has done 34,500 km (about 21,562 miles). My Holden dealer, at the 4 year mark in 2012, as per the service book only changed the timing belt and none of the other ancillary items such as water pump, tensioner pulley, etc. I've read on the net in many places that all items in the "timing belt kit" should be replaced at the same time. The service department here in Australia probably only have instruction to check the condition of the water pump etc while the timing belt is changed. Should I be concerned with the kilometres I drive or don't worry and just have it done at the 8 year mark when the timing belt is next due for replacement? I'm really worried about this.
