Multiquip RE504208 Water Temperature Sensor Engine Side

The Multiquip RE504208 Water Temperature Sensor Engine Side is a genuine OEM component designed for DCA150USJ3CAN and DCA150USJ2 series ultra-silent diesel-powered generators. As a direct factory replacement, this sensor is built to the exact specifications required by the engine-side cooling circuit on these units. Multiquip OEM parts are sourced through the authorized supply chain, ensuring the component you receive matches the original part in fit, form, and function. Confirmed fitment includes DCA150USJ3CAN, DCA150USJ3CAN (FR), and DCA150USJ2 generator models.

Key Features

• Genuine OEM Accuracy — Manufactured to the exact resistance and output specifications required by the engine-side cooling system, ensuring the generator's control circuit receives a correct temperature signal.
• Direct Bolt-In Replacement — Matches the original sensor's thread pitch, connector type, and mounting position, allowing straightforward installation without modification.
• Confirmed Fitment — Verified for DCA150USJ3CAN, DCA150USJ3CAN (FR), and DCA150USJ2 ultra-silent diesel generator models.
• Protects Engine Performance — An accurate water temperature reading allows the generator's management system to regulate cooling and prevent thermal overload during extended runtime.
• Critical Safety Function — A failed or out-of-spec temperature sensor can mask overheating conditions, leading to unplanned shutdowns or engine damage; replacing with a genuine OEM part maintains accurate fault detection.

A water temperature sensor on the engine side monitors the coolant temperature at the engine block and transmits that data to the generator's control system. This reading is used to manage cooling system operation, trigger high-temperature warnings, and initiate protective shutdowns before damage occurs. When the sensor fails or drifts out of calibration, the control system loses visibility into actual engine temperature — increasing the risk of thermal damage and unreliable operation under load.
