Lisle Stretch Belt Installation Tool for GM 5.3L/6.2L/6.6L — Double‑Sided Steel with Long & Short Tabs

Compact, double-sided steel tool designed to install stretch belts on GM 5.3L, 6.2L and 6.6L gas engine pulleys safely and accurately. The Lisle 59560 is a purpose-built belt installation tool for modern GM trucks and SUVs, engineered to speed up and simplify fitment of one-time-use stretch belts without stressing other components. Made from heat-treated steel with a black oxide finish, the tool offers two usable tab lengths so technicians and DIY mechanics can reach both A/C and main drive pulleys across different model years.

Which GM engines and pulleys does this tool fit?

The Lisle 59560 is intended specifically for GM 5.3L, 6.2L and 6.6L gasoline engines where OEM stretch belts are used. Its double-sided design covers the common pulley locations on late-model GM trucks—the long tab addresses A/C belt routing on 2014+ models, while the short tab is shaped for main drive belts on 2019+ vehicles.

• Compatible with GM 5.3L, 6.2L, 6.6L gas engines
• Long tab for A/C pulley applications (2014 and newer)
• Short tab for main drive pulley applications (2019 and newer)
• Works with OEM stretch-style drive belts used on these model years

How does the double-sided design improve belt installation?

The two-tab configuration gives you the correct reach and angle for installing stretch belts without needing multiple tools. By providing a dedicated long and short end, the tool reduces the risk of misalignment, slippage, or damage when positioning a new belt over stationary pulleys.

• Swap between long and short tabs depending on the pulley location
• Reduces force required to stretch and position one-time belts
• Helps maintain correct belt seating and alignment during installation
• Eliminates makeshift bending methods that can harm the belt or components

What materials and finish does the tool use, and why do they matter?

Lisle built the 59560 from heat-treated steel to resist bending or fatigue under repeated use in a garage or shop. The black oxide finish protects the metal from corrosion and provides a low-glare, durable surface suitable for professional environments.

• Heat-treated steel for added strength and longevity
• Black oxide finish for corrosion resistance and reduced glare
• Compact, single-piece construction for reliable leverage

How should I use the tool for safe, efficient installation?

Position the appropriate tab against the pulley and pull the belt into place while keeping pulleys aligned. Use steady, even pressure—avoid sudden bending—so the stretch belt seats correctly. After installation, inspect belt routing and tension per OEM procedure before engine start-up.

• Select long or short tab based on the pulley being serviced
• Apply steady pressure to stretch and guide the belt into grooves
• Confirm belt seating and alignment prior to running the engine
• Store tool clean and dry to preserve the finish and strength

Who is this for: The Lisle 59560 is aimed at professional mechanics, fleet technicians, and experienced DIYers who work on late-model GM trucks and SUVs that use one-time stretch belts. If you routinely service 5.3L, 6.2L or 6.6L gas engines and want a reliable, compact tool to speed belt changes while protecting pulleys and belts, this tool is a practical addition to your toolbox.

FAQ

Q: Will this tool work on non-GM engines?

A: The 59560 is designed for GM 5.3L, 6.2L, and 6.6L stretch-belt applications; fitment on other engines is not guaranteed.

Q: Can the tool damage a stretch belt if used incorrectly?

A: Improper, sudden bending can harm a stretch belt; use steady pressure and the correct tab for safe installation.
