it is recommended that it all the parts (belt and pulleys) are changed after 40,00 miles as the pulleys can fail before the belt prior to 80,00 miles as in the handbook suggests

80,000 miles or eight years. whichever is sooner. Replace the idler and tensioner pullies at the same time, these usually fail before the belt.
