Show original supplier description

The Genuine Lexus 16620-31031 is a direct replacement accessory drive belt tensioner assembly, ensuring a proper fit and function for your vehicle's accessory drive system. This tensioner is crucial for maintaining the correct tension on your serpentine belt, which drives various accessories like the alternator, power steering pump, and air conditioning compressor. It directly replaces the superseded part number 16620-31030. The product specifications include dimensions of 10.7 x 10.2 x 7.9 inches and a weight of 3.10 pounds. This drive belt tensioner pulley kit is compatible with a wide range of Lexus models. Specifically, it fits: 2016 Lexus GS200t (6 Cyl 3.5L), 2006 Lexus GS300 (6 Cyl 3.0L, 3.5L), 2013-2016 and 2007-2011 Lexus GS350 (6 Cyl 3.0L, 3.5L), 2006-2007 Lexus GS430 (6 Cyl 3.0L, 3.5L), 2013-2016 Lexus GS450h (6 Cyl 3.5L), 2008-2011 Lexus GS460 (6 Cyl 3.5L), 2017 Lexus IS Turbo (6 Cyl 3.5L), 2016 Lexus IS200t (6 Cyl 2.5L, 3.5L), 2006-2015 Lexus IS250 (6 Cyl 2.5L, 3.5L), and 2016-2018 Lexus IS300 (6 Cyl 2.5L, 3.5L). It is also listed as compatible with various Toyota models including FJ Cruiser, Highlander, RAV4 III, Sienna, and Venza. However, one forum discussion suggests that 16620-31031 might be for RWD cars, and a different part number (16620-31040) might be the entire tensioner assembly. Always verify fitment with your specific vehicle's VIN.
