Litens 999036A Automatic Belt Tensioner

The Litens 999036A is an automatic serpentine belt tensioner engineered to maintain precise belt tension throughout the accessory drive system. Litens Automotive is the original inventor of the automatic belt tensioner and is a leading OEM supplier trusted by major automakers worldwide, making this a premium replacement that meets or exceeds original equipment standards.

The tensioner uses a spring-loaded pivoting arm with an integrated idler pulley to continuously apply the correct amount of tension to the serpentine belt. This prevents belt slippage, reduces noise, and extends the service life of the belt and driven accessories such as the alternator, power steering pump, air conditioning compressor, and water pump.

Key Features:

• OEM-quality construction from the inventor of the automatic belt tensioner
• Precision-engineered spring mechanism for consistent, automatic belt tension control
• Integrated idler pulley with high-quality bearing for smooth, quiet operation
• Corrosion-resistant materials for long-term durability
• Direct OEM replacement — no modifications required for installation
• Meets or exceeds original equipment specifications

Replacing a worn or failing belt tensioner is a critical maintenance item. A faulty tensioner can cause belt squeal, premature belt wear, accessory failure, and in severe cases, complete belt loss. The Litens 999036A restores proper drive belt system function and is an ideal choice for a reliable, long-lasting repair.
