Multiquip RE52722 Coolant Temperature Sensor Engine Side

The Multiquip RE52722 Coolant Temperature Sensor Engine Side is a genuine OEM component designed for the DCA85USJ2 ultra-silent diesel generator. As a direct OEM replacement sourced through Multiquip's authorized parts network, RE52722 is manufactured to the exact specification of the original sensor installed at the factory. This part is confirmed to fit the DCA85USJ2 series, making it the straightforward choice when you need a verified replacement without guesswork.

Key Features

• Genuine OEM Accuracy — Manufactured to the original electrical resistance and output specification for the DCA85USJ2 engine-side coolant temperature circuit, ensuring the generator's control system receives a correct, calibrated signal.
• Direct Plug-In Replacement — Matches the original connector, thread pitch, and mounting position on the engine side, allowing straightforward installation without modification to wiring or mounting hardware.
• Confirmed Fitment — Verified for the DCA85USJ2 ultra-silent diesel generator; always cross-reference your unit's serial plate and parts manual before ordering.
• Protects Engine and Generator Output — A properly functioning coolant temperature sensor allows the generator's control system to monitor engine thermal load accurately, enabling correct automatic shutdown responses before overheating causes internal engine damage.
• Critical Safety Circuit Component — The engine-side coolant temperature sensor feeds directly into the generator's protective shutdown system; using an OEM-spec sensor maintains the integrity of that safety circuit.

The coolant temperature sensor on the engine side monitors the temperature of the engine's coolant and transmits a continuous electrical signal to the generator's control panel. This data allows the control system to track operating temperature in real time and trigger an automatic protective shutdown if the engine approaches a thermal threshold that could cause serious damage. When this sensor fails or drifts out of calibration, the control panel may display false readings, fail to respond to genuine overheating conditions, or trigger unnecessary shutdowns — all of which affect both equipment reliability and site safety.
