Installation Notes and Tips
Verify the belt routing, pulley style, and mounting location before installation. Confirm the bearing bore, pulley diameter, and width against the original tensioner to ensure the correct accessory drive belt tensioner assembly is selected. Inspect the belt, idler pulleys, and related drive components at the same time so the new tensioner is installed into a clean, serviceable system.
Use the vehicle’s service information for torque specifications and belt routing details. Gates 38506 is listed as an accessory drive belt tensioner assembly with one mounting hole and included bolt, so confirm the application before final assembly on Honda Civic, Toyota Corolla, or other OE-matched vehicles.
