34-Piece Cooling System Service Kit: Combines cooling system pressure testing, vacuum purging, and coolant refilling in one set. Includes a hand pressure pump, vacuum refill tool, 23 adapters, angled hose clamp pliers, thermometer, wrench, hoses, air fittings, clamps, rubber sealing accessories, and a molded case. Test for Cooling System Pressure Loss: The hand pump provides a 0–35 psi (0–2.5 bar) range to help check for pressure loss around radiators, expansion tanks, heater cores, water pumps, hoses, pipes, and related cooling system connections. Vacuum Purging and Coolant Refilling: Connect the vacuum refill tool to a compatible air compressor to remove trapped air and draw coolant into the system. Its gauge offers a 0 to −30 inHg range, while the included European and American air fittings support common workshop connections. 23 Adapters for Broad Coverage: Includes 22 color-coded radiator adapters and 1 universal cone-shaped adapter for a wide range of domestic, European, and Asian cars, SUVs, and light trucks. Molded size markings simplify adapter selection; verify the radiator opening and cap style before ordering. Added Pliers and Sealing Accessories: The angled flat band hose clamp pliers provide improved access to spring clamps in confined engine compartments. Included clamps, O-rings, and rubber sealing pads support secure connections, while the 32–400°F probe thermometer and molded carrying case simplify service and storage.
