The Multiquip 50655900 Low Coolant Sensor LS450 is a genuine OEM component designed for the LS450 hydraulic-driven concrete pump. As a direct OEM replacement, this sensor is built to the exact specification required by the LS450, ensuring accurate coolant monitoring and proper integration with the machine's protection systems. Sourced directly through authorized Multiquip supply channels, the part is the correct part for operators maintaining or restoring their LS450 to full working condition.
Key Features
- OEM Coolant Detection Spec — Engineered to the exact threshold and output signal required by the LS450 cooling system, so the machine's protection circuit responds correctly when coolant drops to a critical level.
- Drop-In Replacement — Matches the original mounting thread, connector, and harness interface of the LS450, allowing straightforward installation without adapters or modifications to the wiring loom.
- Confirmed LS450 Fitment — Verified for the Multiquip LS450 hydraulic-driven concrete pump; use model code LS450 when cross-referencing against your machine's parts diagram.
- Protects Engine and Hydraulic Components — A correctly functioning coolant sensor triggers shutdown or warning before low coolant causes overheating damage to the engine or hydraulic system. A failed sensor leaves the machine running blind to a dangerous condition.
- Electrical Safety Compliance — As a protective safety sensor in the machine's thermal management circuit, using the genuine OEM part ensures the shutdown threshold and signal output remain within the system's designed safety parameters.
The low coolant sensor monitors the coolant level in the engine's cooling system and sends a signal to the machine's control circuit when the level drops below a safe threshold. This triggers a warning or automatic shutdown to prevent the engine from running hot and sustaining serious internal damage. When this sensor fails — whether through a broken float, corroded connector, or degraded signal output — the machine loses that layer of protection entirely, leaving the engine vulnerable to overheating without any alert to the operator.
