What tools are needed for installation?

You typically need a serpentine belt tool or a long-handled socket wrench to release tension, and a torque wrench for final installation.

Is the pulley included with the tensioner?

Yes, the Gates DriveAlign unit comes as a complete assembly including the tensioner housing, spring, and the pulley.

Can I use this tensioner on any engine?

No, this part is engineered for specific vehicle applications. Never force a part that does not match your vehicle's specifications.

Troubleshooting

Pros and Cons

Pros

  • Meets or exceeds original equipment (OE) quality standards
  • Reduces vibration and belt noise
  • Easy to identify compatibility using part number T38239
  • Prevents accessory failure due to improper belt tension

Cons

  • Requires professional-grade tools for safe spring tension release
  • Compatibility is strictly limited to specific vehicle engines
  • May be difficult to access depending on engine bay layout

Setup, Compatibility & Care

Before installation, use a serpentine belt tool to relieve pressure from the existing belt. Always verify the routing diagram for your specific engine, as improper routing will lead to immediate failure. When installing the T38239, clean the mounting surface of all debris and torque the mounting bolts to the manufacturer’s specified values; over-tightening can crack the housing, while under-tightening may lead to vibration. Periodically inspect the pulley face for signs of glazing or cracks, especially when replacing the serpentine belt, as a worn pulley can damage a new belt in short order.
