Dave, just if you could let me know a price, as im not sure if pulleys were done, the sticker is a gates sticker so i guess thats the belt but i cant read if it says pulleys etc were done?
if you are unsure of the history, i would change them for peace of mind. the cost of repairing it if it goes wrong greatly outways the cost of fitting them now as preventative maintainance. also check the waterpump.
