GEAROLL 43300 is an eight-piece pneumatic fan clutch wrench kit designed to remove stubborn fan clutches quickly using an air hammer.

This professional-grade removal set was created for mechanics and DIYers who need a fast, reliable way to free fan clutches on Ford, GM, Chrysler and Jeep engines. The kit includes multiple drive wrench sizes, a long leverage handle and a molded storage case so you can carry the right wrench for a range of V6 and V8 applications. Built from hardened steel with a protective black finish, the components resist corrosion and hold up under repeated shop use.

Which vehicles and engines will this fan clutch wrench fit?

The GEAROLL 43300 kit covers many common passenger truck and SUV fan nut sizes used on Ford, GM, Chrysler and Jeep platforms, including several 4.3L, 5.0L and 5.7L GM engines. Before buying, verify the fan nut diameter on your vehicle to match the included wrench sizes. The kit is especially useful for older model trucks where the clutch is seized from heat and grime.

• Compatible makes: Ford, GM, Chrysler, Jeep
• Common engine fitment: 4.3L, 5.0L, 5.7L GM pick-ups
• Check vehicle-specific fan nut diameter prior to use

How do I use the pneumatic fan clutch wrench safely?

Using the set requires an air hammer (not included) and basic shop safety precautions. Slide a chosen wrench onto the air hammer, engage the fan nut area, and apply short controlled impacts until the clutch loosens. Wear eye protection, gloves and ensure the engine is cool before starting work.

• Attach selected wrench size to an air hammer — air hammer sold separately
• Use short, controlled impacts to avoid damage to the fan or shroud
• Wear PPE and allow the engine to cool before removing the fan clutch

What tools and parts are included and how durable are they?

The kit ships with seven interchangeable drive wrenches, a long 17" handle for manual leverage, and a blow-molded case that organizes the components for easy transport. Each wrench is manufactured from high-strength steel with a black finish to reduce wear and resist surface rust. This construction helps the kit survive frequent use in a busy garage environment.

• Included sizes: 32mm, 36mm, 40mm, 47mm, 7/8", 1-7/8", 2"
• One 17" long handle for added leverage when needed

Can this kit replace specialized pinning tools or additional adapters?

The GEAROLL set is intended to work with air hammer impact action so you typically won’t need extra pinning tools for fan clutch removal. Because the kit provides several common wrench diameters, it often eliminates the need for multiple individual adapters. Confirm size fitment and your chosen removal method before proceeding.

• No special pin tools usually required for air-hammer removal
• Multiple wrench sizes reduce the need for extra adapters
• Air hammer compatibility is essential; the air hammer is not included
