Multiquip 3940632 Thermostat - OEM Replacement Part for Super Silent Generators

This thermostat regulates coolant temperature in the water-cooled diesel engine system of Multiquip's Super Silent generator series. Proper thermostat operation is critical for maintaining optimal engine operating temperature, preventing both overheating and inefficient cold-running conditions that can lead to premature engine wear, reduced fuel efficiency, and potential generator shutdown.

The DCA300SSC series generators are powered by 6-cylinder, 4-cycle, water-cooled, direct-injection diesel engines (Cummins QSL9-G3) that require precise temperature regulation for reliable performance. A failing thermostat can cause erratic temperature readings, overheating alarms, or engines that run too cool, leading to incomplete combustion and increased maintenance requirements. In cold climate applications where jacket water heaters are utilized, maintaining proper thermostat function is especially important for consistent generator operation.

This thermostat is designed specifically for Multiquip's WhisperWatt™ Super Silent generator series, which feature sound-attenuated enclosures and advanced excitation systems requiring consistent engine temperatures for optimal power output and voltage regulation.

Compatible Models:

• DCA300SSC
