Gates T43271 Engine Timing Belt Tensioner

Gates T43271 Timing Belt Tensioner

The Gates T43271 timing belt tensioner is built for OE-quality fit and OE-exact performance in Subaru timing systems. It is engineered to maintain proper belt tension, support belt life, and eliminate the need for a separate tensioning operation during installation.

Compatible with Subaru WRX STI, WRX, and Impreza applications that use interference engines, this Gates timing belt tensioner is a direct replacement for the factory-style hydraulic unit. The steel construction, smooth backside contact surface, and included bracket hardware details make it a focused solution for timing service on the Subaru WRX STI and related models.

Key Features

• OE Exact comparison rating for factory-style fit and function
• Hydraulic tensioner design for controlled belt tension
• Steel construction for durability in engine service
• Smooth/backside pulley contact surface
• Single-pulley design with 32 mm inside diameter, 34 mm width, and 60 mm outside diameter
• Includes tensioner, bracket, bolt, and Loctite threadlocker

Product Details

Gates PowerGrip timing tensioners are designed and tested to match OE-quality or OE-exact requirements, helping maintain consistent timing belt tension across the service interval. The hydraulic design supports stable operation in Subaru timing belt systems, while the smooth backside contact surface is suited to the belt routing used in these applications. This part cross-references Subaru 13033AA050 for the same application.

Use the Gates T43271 when servicing timing components on 2013-2021 Subaru WRX STI, 2013-2016 Subaru WRX, and 2013-2014 Subaru Impreza. It is a direct-fit timing belt tensioner for Subaru WRX STI timing belt service and Subaru Impreza timing belt replacement where OE-style hydraulic tension control is required.

Common Issues This Part Can Address

• Timing belt slack caused by a worn hydraulic tensioner
• Noise from a failing timing belt tensioner assembly
• Uneven belt tension during engine operation
• Timing service concerns on interference-engine Subaru applications
• Need for OE-style replacement during Subaru timing belt maintenance

Installation Notes

Install the tensioner during timing belt service and follow the vehicle-specific service procedure for belt alignment, torque values, and hydraulic tensioner setup. Verify all timing marks before engine start-up, especially on interference-engine Subaru WRX STI, WRX, and Impreza applications. The included Loctite threadlocker is provided for use during installation where specified by the service procedure.

Quality Assurance

Gates PowerGrip timing tensioners are engineered and tested to meet OE-quality or OE-exact expectations for fit and performance. The T43271 is built to help maintain optimal belt tension and support reliable timing system operation in Subaru applications.
