SANY 60133548 Engine Overheat Alarm Switch For SANY Excavator
●SANY 60133548 Overheat Alarm Switch Technical Support
●The 60133548 Overheat Alarm Switch (Switch, overheat alarm / 过热报警开关) functions as a critical engine safety thermo-switch on compatible SANY hydraulic excavators.
●Material number 60133548 is installed into the engine cylinder head coolant gallery or thermostat housing, directly sensing engine coolant thermal changes. When engine coolant temperature exceeds the calibrated high-temperature safety threshold, the switch contacts trigger an immediate electrical warning signal to the excavator central controller (ECU) and cab instrument panel/buzzer, alerting operators and initiating engine derate protection to prevent cylinder head cracking and engine seizure.
●Verify mounting thread pitch, probe immersion length, alarm trip temperature threshold, and electrical terminal connector style prior to order confirmation.
Compatibility note: Cataloged in parts directories and parts manuals for SANY hydraulic excavators (including SY75C, SY75C3I3R, SY75C9, SY75C9I3H, SY500 series engine and cooling system electrical harnesses). Verify machine serial number and engine model before ordering.
