{"type":"firestarter.listing","listing":{"id":"lst_DDcrq7Mu","product_name":"Powerbuilt Master Fan Clutch Wrench Set - 647759","category":"Specialty Tools - Cooling","description":"The right tools for the job make a project go smoother and quicker. Servicing a viscous fan clutch is one of those jobs. The Powerbuilt master Fan Clutch Wrench Master Set is designed to remove threaded-on viscous fan clutches on Ford, Chrysler, Jeep, and some imported vehicles with these strong heat-tempered steel fan clutch wrenches. The larger wrench keeps the water pump shaft from spinning while you loosen the fan clutch nut with the appropriate smaller wrench. Wrenches are 1/2 inch square drive, allowing the use of breaker bars and ratchets. The wrenches' black finish is strong and durable for a lifetime of use. The set comes in a sturdy blow-molded hard case with professionally written usage instructions and photos. All Powerbuilt installer kits meet or exceed ANSI standards.","images":["https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647759-02.jpg?v=1774180564","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647759_APC_1.jpg?v=1774180564","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647759_APC_2.jpg?v=1774180564","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647759_APC_3.jpg?v=1774180564","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647759_APC_4.jpg?v=1774180564","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647759_APC_5.jpg?v=1774180564","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647814-07_1f4a7e7d-d83f-4157-b300-752a39e52a34.jpg?v=1774180564"],"price":99.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:27:12.175Z"},"share_url":"https://firestarter.network/l/lst_DDcrq7Mu","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
