• Seamless Integration: Designed as a direct replacement and enhancement for Lisle Serpentine Belt Tool Sets 57800 and 57900.
• Enhanced Leverage: Provides additional leverage for loosening stubborn tensioners and ensures proper belt installation without damage.
• Versatile Compatibility: Facilitates serpentine belt removal and installation on a wide range of vehicle models, including most domestic and many import applications.

Applications

This long extension is essential for mechanics and technicians performing routine maintenance and repairs on serpentine belt systems. It is particularly valuable when working on vehicles with transverse-mounted engines or those with limited clearance around the serpentine drive, alternator, water pump, and A/C compressor. The extension proves critical for accessing tensioner arms with 3/8-inch or 1/2-inch square drive receptacles. Its design helps to prevent damage to belts and pulleys by allowing for precise and even force application during installation and removal. Beyond serpentine belt service, this robust extension can also serve as a leverage aid for other automotive tasks requiring extra reach or breaking torque with standard sockets.
