I recently bought an 06 Impreza 2.0RX for use over the winter. The car has a full service history and had a full service including plugs, fuel filter, gearbox and diff oil just before I bought it but I cant find any record of the timing belt being done at any stage. There is just shy of 90k miles on the car and so its more than due a belt. Is there a need to buy a full belt kit including pulleys or will changing the belt suffice? The car drives 100% and there are no issues with any of the pulleys that I'm aware of. Theres quite a difference in the cost of the kit v belt and the labour cost for doing just the belt compared to pulleys and belt. Like I said its just a winter car, it'll only be on the road if we get snow and even then I wont be doing any more than 500-1000 miles a year but do intend to keep the car for a few years.
