Description
Keep your alternator, water pump, power steering, and A/C compressor running smoothly by applying consistent, correct pressure on the drive belt. This prevents belt squeal, premature belt wear, and accessory drive failure. Therefore, you must eliminate loose belts, slipping pulleys, and charging or cooling issues.
Built with a heavy-duty internal spring mechanism and a precision-machined pulley bearing, this original belt tensioner handles continuous engine vibration and high rotational speeds effortlessly. Also, it matches factory mounting points and arm alignment precisely so installation is exact and secure.
Cheap copy tensioners use weak springs that lose tension quickly and low-quality bearings that seize up under heat. Consequently, they cause your belt to snap or slip off, leaving you stranded with a disabled engine.
