Golden Dragon Higer Bus Yuchai Engine Belt Tensioner AN1000-1002450
Product Description
Ensure the reliability and peak performance of your fleet's Yuchai engines with the premium Automatic Belt Tensioner from Nanjing Dingguan Auto Parts Co., Ltd. Part number AN1000-1002450 is a vital component, specifically engineered for the demanding duty cycles of King Long and Higer buses.
This tensioner is the key to maintaining the correct tension on the engine's main serpentine belt. It ensures that all critical accessories—such as the alternator, water pump, and power steering pump—are driven efficiently and consistently. A failing tensioner can lead to belt slippage, squealing noises, and ultimately, a snapped belt, causing an immediate and costly vehicle breakdown.
Key Features & Benefits:
- Automatic Tension Adjustment: Our tensioner’s robust internal spring mechanism automatically maintains the perfect tension on the serpentine belt, compensating for belt stretch and wear over time.
- Precise Compatibility: Designed as a direct, bolt-on replacement for part AN1000-1002450 on Yuchai engines, guaranteeing a perfect fit for King Long and Higer models and a hassle-free installation.
- Enhanced Durability: Featuring a high-quality, sealed pulley bearing and a rugged cast-aluminum body, this component is built to withstand extreme engine temperatures and vibrations for a long, dependable service life.
- Prevents Critical Failures: Proactively replacing a worn tensioner is essential to prevent unexpected downtime and protect your engine from the severe damage that a belt failure can cause.
As a specialized manufacturer, Nanjing Dingguan is committed to providing engine components that keep your fleet operational and profitable.
