J71007-89 is a precision aviation maintenance tool compliant with AS9100D standards and FAA/EASA regulations, dedicated to aircraft engine cooling systems and ground support line maintenance. Forged from high-strength anti-corrosion alloy steel with heat-resistant coating, it withstands -55℃ to 180℃, resisting coolant erosion, high-temperature oxidation and vibration for stable, durable performance in frequent MRO operations. Specialized in disassembling, installing and calibrating engine coolant hoses, radiator connectors and thermostat valves, it features precision-machined non-damaging working ends with tight tolerances to avoid leaks and cooling failure, critical for engine temperature control and operational reliability. Its compact, ergonomic design fits confined engine bays, matches mainstream aviation specs, streamlines workflows, cuts ground downtime, safeguards cooling system integrity, and is an indispensable tool for aero-engine stability and overall flight safety.
