Product Description

The Gates 38170 OE-Exact Belt Tensioner is designed to restore or upgrade the accessory drive system on compatible 3.0 L inline-six Lexus and Toyota engines from the 1990s to mid-2000s. Engineered to meet OEM specifications, its steel housing and precision bearings ensure stable, reliable tension for serpentine/V-ribbed belts - maintaining proper drive of alternator, power steering, A/C compressor, and other belt-driven accessories. That makes it an ideal replacement when worn tensioners cause belt slippage, noise, or inconsistent accessory operation.

Thanks to its direct-fit mounting and OE-exact dimensions, the 38170 installs without modification or special tools. The built-in torsion spring and vibration-damping design also help prolong belt and accessory life by ensuring consistent tension over time and reducing mechanical stress. If you drive a 1993-2005 GS300, 1992-2000 SC300, 2001-2002 IS300, or 1993-1998 Supra with a 3.0 L I6, this tensioner provides a dependable, OEM-level replacement to restore proper accessory drive performance.
