Premium Belt Tensioner for Yuchai Engines with PN G5AYA-1002450SF1 and Temperature Range -40℃~125℃ Zinc Coated

The reliability of your fleet's Yuchai engines depends on every component working in perfect harmony. At the heart of this system is the serpentine belt, and its performance is dictated by the Automatic Belt Tensioner. Nanjing Dingguan Auto Parts Co., Ltd. manufactures this high-quality replacement, part number G5AYA-1002450SF1, engineered for King Long, Kingwin (JINLÜ), and Yutong buses.

This tensioner's job is to maintain constant, optimal pressure on the belt that drives critical accessories like the alternator, water pump, and power steering pump. A worn or failing tensioner can quickly lead to squealing belts, loss of power to these systems, and ultimately, a costly roadside breakdown.

• Automatic Tension Control: Our tensioner's robust internal spring automatically compensates for belt wear and stretch, eliminating belt slippage and ensuring all engine accessories are powered efficiently.
• Broad Fleet Compatibility: Designed as a direct, bolt-on replacement for part G5AYA-1002450SF1, this component provides a versatile, single-part solution for your mixed fleet of King Long, Kingwin, and Yutong buses.
• Enhanced Durability: Features a high-quality pulley with a smooth-running, sealed bearing, engineered to withstand the extreme heat and vibrations of the engine bay for a long, dependable service life.
• Prevents Costly Downtime: Proactively replacing a worn tensioner is a small, smart investment that prevents unexpected belt failures, protecting your engine from damage and keeping your vehicles on the road.
