Volvo D13 Mack MP7 Belt Tensioner – Continental Elite OE – Replaces 21819687

Ensure the reliable performance of your engine’s accessory drive with the Volvo D13 Mack MP7 Belt Tensioner by Continental Elite. As an Original Equipment (OE) level component, this tensioner is engineered to maintain the precise amount of belt tension required to prevent slippage and premature wear on your alternator, water pump, and AC compressor. Built for the high-torque environments of Mack and Volvo diesel engines, it eliminates belt squeal and reduces vibration, extending the life of your entire serpentine system.

OE Engineering: The Volvo D13 Mack MP7 Belt Tensioner Advantage

The Volvo D13 Mack MP7 Belt Tensioner (Automann Part # 816.49608) features Continental’s advanced internal damping system. This technology absorbs the high-frequency vibrations produced by heavy-duty diesel engines, preventing the tensioner arm from "chattering" and protecting the engine bearings from shock loads. Note: Manufactured with a high-strength cast aluminum housing and a precision-ground pulley, this assembly provides the factory-spec fit and durability required for long-haul duty cycles.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize drive components that keep your cooling and charging systems fully operational. This assembly is a direct professional-grade replacement for Mack 21819687 and Contitech 49608. It is widely used across the Volvo VNL and VNR series as well as Mack CXU models, ensuring a reliable fix for active belt-drive issues.
