What is the Serpentine belt routing on a Volvo 2.5TDI?

The serpentine belt routing on a Volvo 2.5TDI typically involves a path that goes around several pulleys, including the crankshaft, alternator, Power Steering pump, and the water pump. The belt starts at the crankshaft pulley, loops around the tensioner pulley to maintain proper tension, and then routes through the various components in a specific sequence. It's essential to refer to a service manual for the exact routing diagram, as it can vary slightly based on the model year and specific engine configuration. Always ensure the belt is properly tensioned and aligned to avoid wear and potential failure.
