With the right tool, it’s easy. The Powerbuilt Cooling System Pressure Test Pump Kit is a heavy-duty 3 stage pump and hose you can attach to a vehicle’s various pressurized systems to track down the problem easily. The easy-to-read pump gauge displays pressure ranges of 17-19 lbs., 20 lbs., and 28-30 lbs., with a color-coded dial that makes it simple to test higher pressure caps and systems accurately. Use the correct Powerbuilt coolant system adapter for the vehicle, attach the pump, and pressurize to see if there’s a leak or a faulty component. The kit comes in a heavy-duty organizing carry case with usage photos and detailed instructions.","images":["https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642-a.png?v=1774180545","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642_APC_1.jpg?v=1774180545","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642_APC_2.jpg?v=1774180545","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642_APC_3.jpg?v=1774180545","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642_APC_5.jpg?v=1774180545","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642_APC_4_a9l0yf.jpg?v=1774180545","https://cdn.shopify.com/s/files/1/0443/2681/3852/files/647642_APC_6_czdgfz.jpg?v=1774180545"],"price":119.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:27:09.762Z"},"share_url":"https://firestarter.network/l/lst_8CFzbRha","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
