A damper and pulley assembly for an internal combustion engine is disclosed. The damper and pulley assembly, including a pulley closely fitted between two dampers, is configured to have increased air movement for heat dissipation while conforming to low spacing requirements of an engine compartment. The pulley can have multiple slots along its two side surfaces and openings located in the slots. The slots and openings of the pulley are aligned with openings of the two dampers, and facilitate air movement through the pulley and around the dampers.
