The Multiquip 3940632 Thermostat Without is a genuine OEM cooling system component designed for DCA300SSC, DCA300SSCU, and MQP240 series diesel-powered generators. As a direct OEM replacement, this thermostat is manufactured to the same specifications as the original unit, ensuring proper coolant regulation and engine temperature management on your Multiquip generator. Sourced directly through authorized Multiquip supply channels, part number 3940632 is a reliable, drop-in solution to restore correct thermal control to your machine. DHS Equipment stocks this part to keep your generator running at the temperature range it was engineered for.
Key Features
- Genuine OEM Cooling Precision — Manufactured to exact OEM tolerances, ensuring the thermostat opens and closes at the correct temperature threshold for these diesel generator engines.
- Direct-Fit Installation — Engineered to seat and seal in the original thermostat housing without modification, maintaining proper coolant circuit integrity.
- Confirmed Generator Fitment — Verified for DCA300SSC, DCA300SSCU, and MQP240 diesel-powered generator models using Multiquip's OEM parts database.
- Protects Engine from Thermal Stress — A functioning thermostat keeps the engine operating in its optimal temperature band, preventing overheating and the damage it causes to seals, head gaskets, and internal components.
- Maintains Coolant Flow Timing — Correct valve actuation ensures coolant reaches the radiator at the right moment, supporting stable output performance during sustained generator operation.
The thermostat is a valve within the engine cooling system that controls when coolant flows from the engine to the radiator. When the engine is cold, the thermostat stays closed so the engine reaches operating temperature quickly. Once the target temperature is reached, it opens to allow coolant to circulate through the radiator and shed heat. A failed or stuck thermostat can cause the engine to overheat — or in some cases run too cold — both of which reduce efficiency, increase wear, and can lead to costly engine damage if left uncorrected.
