Keep the accessory drive belt tracking true and quiet with the Four Seasons Idler / Tensioner Pulley (P/N 45973). This smooth, back-side idler pulley rides on the flat side of the serpentine accessory belt to route it and help hold proper tension. It drops in as a direct-fit replacement for the listed applications, including the 1987-1989 Buick Century [V6-2.8L], 1990-1997 Chevrolet Lumina [V6-3.1L], 1997-2008 Ford F-150 [V6-4.2L] and 2005 Dodge Stratus [V6-2.7L].
Steel and thermoplastic build: combines the two materials for longer life and superior dampening.
High-grade bearings: made to withstand higher operating temperatures.
Smooth pulley face: a back idler with a smooth groove that contacts the back of the belt.
Steady tracking: helps hold the belt against slip and the noise slip can cause.
Specs: 3.500 in (88.9 mm) outside diameter, 1.000 in (25.4 mm) belt width, and a single mounting hole.
