We strongly suggest replacing the crankshaft bolt (a stretch bolt) on the front end of the crankshaft at the same time. See this bolt (two different versions), listed below.
Only for models with standard A/C, which has a single A/C compressor. NOT for models with rear A/C which has a second A/C compressor (One above the other). See this other version pulley below.
Detailed Description
Sprinter 2002-2006
Not for vehicles with accessory rear A/C having a 2nd A/C compressor, which is driven by a second belt, a V-belt. Those vehicles require a special two-belt pulley that is shown below.
