Fits 2005-2011 Volvo V50, N/A, VIN 202465 & After; interference engine application. Gates T43172 is a direct-fit timing belt tensioner for these Volvo models.

Common Timing Belt Issues It Addresses

• Incorrect timing belt tension after service
• Belt noise caused by worn or weak tensioner components
• Premature timing belt wear from inconsistent pulley pressure
• Timing instability in interference-engine applications
• Service delays from replacing a worn tensioner during belt maintenance

Installation Notes

Verify engine code and VIN breakpoints before installation, especially on 2004-2012 Volvo S40 and 2005-2011 Volvo V50 applications listed with VIN 202465 & after. Inspect the timing belt, pulleys, and related wear components during service, and follow the vehicle manufacturer’s timing procedure exactly. Proper alignment and torque are important on interference engines.
