There are two of these on most Sprinter 5-cylinder engines. Some models may use a smooth and smaller upper pulley. See below.
*If your Sprinter is a 2004-2006 model and the original upper pulley fitted to your engine is smooth and slightly smaller (54 mm) in diameter, this slightly larger ribbed pulley can be used as a replacement unit. This ribbed pulley may be used replacement for both upper and lower idlers on the Dodge parts diagram. Either pulley may be used in the upper position. The choice is up to you.
