The A-Premium Belt Tensioner Assembly with Pulley is a direct-fit replacement tensioner that restores correct belt tension for select Toyota, Lexus and Scion 4‑cylinder engines.

How does this tensioner match original equipment performance?

The unit is manufactured to OEM‑style tolerances with the same critical dimensions—pulley diameter, bearing bore and width—so belt tracking and tension behaviour are consistent with factory parts. Using matching dimensions reduces misalignment, belt wear and accessory noise when installed correctly.

• Pulley outside diameter: 70 mm for correct belt wrap
• Bearing bore inside diameter: 17 mm to fit original shaft sizes
• Pulley width: 24 mm to support V‑ribbed belt profile
• Single pulley configuration designed for the specified accessory routing

What should I expect during installation and service life?

Installation follows the factory service procedure: relieve belt tension, remove the old tensioner, install the new assembly and retension the belt to specification. When fitted and torqued to the manufacturer’s instructions, this tensioner provides reliable tensioning and reduces premature belt failure and squeal due to worn tensioner components.

• Direct bolt‑on replacement — uses factory mounting points
• Accepts standard V‑ribbed belts used on listed vehicles
• Replacement recommended when the original shows play, noise, or bearing roughness
• Inspect belt and accessories during installation for complete reliability
