- a drive pulley connected to a crankshaft for rotation therewith and located at a lower central portion of the engine;
- a first accessory aggregate pulley which, when seen in a vertical direction, is located above said drive pulley and, when seen in a horizontal direction, is spaced in a first direction from said drive pulley;
- an accessory aggregate pulley set including a second accessory aggregate pulley which, when seen in a horizontal direction, is spaced in a second direction opposite to said first direction from said drive pulley;
- and
- an idler/tensioning pulley set which includes an adjustable tensioning pulley and two idler pulleys which, when seen in a horizontal direction, is spaced in said second direction from said drive pulley and is located between said drive pulley and said accessory aggregate pulley set, with a serpentine belt extending from said drive pulley to said tensioning pulley and from said tensioning pulley to said first accessory aggregate pulley.
