The Multiquip 5137700301 Thermostat is a genuine OEM component designed for DCA45SSIU2 series ultra-silent diesel powered generators. As a factory-sourced part, it meets the exact specifications required for proper engine coolant temperature regulation in the DCA45SSIU2, DCA45SSIU2-GEER, and DCA45SSIU2-FEMA models. Sourcing the correct OEM thermostat ensures your generator maintains the thermal management performance it was built to deliver. DHS Equipment stocks this part for fast fulfillment and verified fitment accuracy.
Key Features
- Genuine OEM Temperature Calibration — Factory-set opening temperature matches the original coolant circuit spec for the DCA45SSIU2 engine, ensuring accurate thermal regulation rather than an approximate range.
- Direct Drop-In Replacement — Engineered to seat directly into the original thermostat housing without modification, using the same flange dimensions and seal interface as the outgoing part.
- Confirmed Fitment for DCA45SSIU2 Series — Compatible with DCA45SSIU2, DCA45SSIU2-GEER, and DCA45SSIU2-FEMA ultra-silent diesel generator models.
- Sustained Engine Operating Efficiency — A correctly functioning thermostat keeps the engine in its optimal temperature band, supporting fuel efficiency and stable power output during extended generator run times.
- Cooling System Integrity — A failed or stuck thermostat can cause chronic overheating or under-temperature running, both of which accelerate engine wear and risk unplanned shutdowns on critical power applications.
The thermostat is a valve in the engine's cooling circuit that regulates coolant flow based on operating temperature. When the engine is cold, the thermostat remains closed, allowing the engine to reach its optimal operating temperature quickly. Once that threshold is reached, the valve opens to route coolant through the radiator and dissipate excess heat. A thermostat that sticks open causes the engine to run too cool and inefficiently; one that sticks closed causes rapid overheating. Replacing a faulty thermostat promptly protects the engine and maintains consistent generator performance.
