THERMOSTAT (P/N 99717-000) - As Removed

The 99717-000 is an aircraft thermostat that senses engine oil temperature and automatically regulates coolant flow through bypass circuits. This temperature-sensing component maintains optimal powerplant operating conditions by switching flow paths based on thermal input, preventing overheating or excessive cooling. Commonly installed in engine oil cooling systems on general aviation and business aircraft.

Installation and function verification must follow the applicable engine or airframe maintenance manual before return to service. The thermostat integrates into existing cooling assemblies and requires proper orientation and torque per OEM specifications.
