change at 120,000 km (74,564 miles)
replacement time is 2.9 hours
there are 2 belts kits
1. injection pump belt + tensioner pully
2. cam belt + tensioner + tensioner pully + waterpump + guide pully
the belts alone are not expensive, but all the add-ons are.
From a non main dealer you could save over �300 for the same job.
Some garages wil offer to change the belts for less than �200, but they will proberly change just the belts... This is NOT advised.
p.s i was working from memory for the belt kit inventory.. i mabe slightly wrong.
