Mubea 32402904 Drive Belt Tensioner

The Mubea 32402904 is an OEM-quality drive belt tensioner engineered to maintain precise serpentine belt tension throughout the full range of engine operating conditions. Mubea has been developing and producing friction-damped belt tensioners for combustion engine auxiliary drive systems for over 30 years, and this unit is built to the same exacting tolerances as original equipment.

A properly functioning belt tensioner is critical to the reliable operation of engine-driven accessories. A worn or failed tensioner can allow belt slippage — causing reduced output from the alternator, power steering pump, and air conditioning compressor — or allow excessive belt vibration that accelerates wear on the belt and accessory pulleys.

Key Features:

• Friction-damped tensioner design maintains consistent belt force under varying engine loads and temperatures
• Engineered to OEM specifications for precise fit and function
• Helps eliminate belt squeal, slippage, and premature belt wear
• Suitable for conventional belt drive systems
• Manufactured by Mubea, a trusted Tier 1 OEM supplier to major European and domestic automakers

Replace the drive belt tensioner any time the serpentine belt is serviced, or when symptoms such as belt noise, visible tensioner wear, or irregular belt tension are present. The Mubea 32402904 restores factory-correct belt tension and helps protect downstream accessory components.
