The Multiquip 43140-18 Coolant Temp Sensor is a genuine OEM component designed for STXDF series super-sized hydrostatic ride-on power trowels. As a direct OEM replacement, this sensor is built to the exact electrical specifications required by the engine management system on STXDF equipment, ensuring accurate temperature readings from the moment it is installed. Sourced directly from Multiquip, part 43140-18 delivers the fitment accuracy and signal reliability that operators and service technicians depend on to keep these machines running safely.
Key Features
- OEM-Matched Signal Output — Built to the precise resistance and voltage output specifications required by the STXDF engine management system, ensuring accurate coolant temperature readings without calibration adjustments.
- Direct Drop-In Replacement — Matches the original connector, thread pitch, and housing dimensions for a straightforward installation into the existing sensor port.
- Confirmed STXDF Fitment — Verified for Multiquip STXDF super-sized hydrostatic ride-on power trowels with dual fuel capability.
- Protects Against Overheating Events — A functioning coolant temp sensor allows the engine control system to respond to rising temperatures in real time, helping prevent costly thermal damage to the engine.
- Electrical Safety Compliance — As a critical engine monitoring component, using the correct OEM sensor ensures the temperature warning and shutdown systems operate within designed parameters.
The coolant temperature sensor monitors the operating temperature of the engine coolant and transmits a corresponding electrical signal to the engine control system. This real-time data allows the system to adjust fuel delivery, trigger warning indicators, or initiate a protective shutdown if temperatures exceed safe thresholds. When the sensor fails or reads inaccurately, the engine becomes vulnerable to undetected overheating, which can lead to serious internal damage and unplanned downtime on the worksite.
