Multiquip P3206 Engine Coolant Temperature Sensor

The Multiquip P3206 Engine Coolant Temperature Sensor is a genuine OEM component designed for C30HDNI series Mayco concrete pumps. As a factory-sourced part, it meets the original design specifications required to keep the engine management system operating accurately on C30HDNI and C30HDNI Precision equipment. Sourced directly through Multiquip's OEM supply chain, this sensor is the correct replacement when the original unit fails or reads inaccurately. Verify your model code before ordering to ensure a proper fit.

Key Features

• OEM-Grade Sensing Accuracy — Manufactured to the original electrical resistance and output specifications, ensuring the engine control system receives accurate coolant temperature readings.
• Direct Drop-In Replacement — Engineered to match the original mounting thread, connector, and harness interface on C30HDNI concrete pumps for a straightforward swap.
• Confirmed Fitment — Compatible with C30HDNI and C30HDNI Precision Mayco concrete pump models.
• Protects Engine from Overheating Events — A functioning coolant temperature sensor allows the engine to respond correctly to thermal changes; a faulty sensor can mask dangerous overheating conditions or trigger false shutdowns.
• Critical Fuel System & Engine Safety Component — On concrete pump engines, accurate coolant temperature data directly influences fuel delivery and ignition timing, making sensor integrity essential to safe and compliant operation.

The engine coolant temperature sensor monitors the temperature of the coolant circulating through the engine and sends that data to the engine control unit. This reading is used to adjust fuel mixture, ignition timing, and cooling fan operation to keep the engine running within its safe thermal range. When the sensor fails or drifts out of calibration, the engine may run too rich, overheat without warning, or shut down unexpectedly — all of which can interrupt pumping operations and risk engine damage.
