The ZTech Belt Tensioner (22674901 / 85023371) maintains proper serpentine belt tension on Volvo D13 engines in VNL trucks. The belt tensioner automatically adjusts belt tension as the belt stretches with use, ensuring consistent drive of the alternator, coolant pump, and other accessories. A worn tensioner allows belt slippage, causing charging system faults, overheating, and power steering failure. ZTech tensioners are manufactured to European OEM specifications for reliable long-term performance.

Q: Which trucks and engines does this belt tensioner fit?
A: Fits Volvo VNL trucks with D13 engines. Replaces OEM part numbers 22674901 and 85023371.

Q: What symptoms indicate a failing belt tensioner?
A: Belt squealing, visible belt flutter, charging system warning lights, and visible wear or cracks on the serpentine belt.

Q: What is included with this tensioner?
