Solution Kits: Ford F-Series Trucks Gary and Monika Wescott, international explorers with the Turtle Expedition, rely on NAPA's Solution Kit for 1999-2003 Ford F-series trucks with 7.3L diesel engines. It routes a hose around the accessory drive system to reduce replacement time and labor costs.
Diagnosing Belt Noise: Using the Spray Bottle Test Whereas belt chirp generally indicates misalignment between the pulley and idlers, belt squeal points to a loss of tension in the system. Use a spray bottle test to determine the cause of belt noise in your Accessory Belt Drive System (ABDS).
Subaru Stretch Fit® Belts For car manufacturers, self tensioning belts allow for greater flexibility in engine design and reduce the overall complexity of the primary belt drive system. For automotive technicians, installing these belts is radically different from standard V-ribbed belts. Follow this video for detailed installation instructions.
Alternator Decoupler Pulley: How to Inspect and Replace Learn how to reduce belt drive system vibrations with specialized, high-tech alternator pulleys that reduce belt drive system vibrations, improve engine efficiency and increase the life of the belt and tensioner.
