Detailed Product Overview

This Gates 39297 automatic belt tensioner assembly is engineered for the accessory drive belt system on 2011-2015 Honda CR-Z and 2010-2014 Honda Insight models. It uses a steel body, a single flanged pulley, and a V-ribbed grooved contact surface to maintain proper belt tension and pulley engagement. The 17 mm bearing bore, 70 mm outside diameter, and 19 mm width reflect the OE-style dimensions needed for accurate replacement service. This part cross-references Continental 49487 for the same application.

Common Issues This Part Can Address

• Belt squeal caused by weak or inconsistent tension
• Accessory belt flutter or visible belt movement
• Improper belt tracking across the pulley system
• Noise from a worn tensioner pulley or bearing
• Loss of stable belt tension in the accessory drive system

Installation Notes and Tips

Verify the vehicle application before installation by matching the year, model, and accessory drive belt layout. Inspect the belt, idler pulleys, and surrounding components for wear before replacing the tensioner. Confirm pulley alignment and belt routing after installation so the V-ribbed belt seats correctly in the grooves.
