The Multiquip 200438 Thermostat LS300 is a genuine OEM component designed for the LS300 hydraulic-driven concrete pump. As a direct OEM replacement, this thermostat is built to the exact specification required by the LS300, ensuring the engine cooling system operates within its correct temperature range. Sourced directly through the Multiquip parts network, the part is the correct service part for maintaining thermal regulation on LS300 equipment.
Key Features
- OEM-Calibrated Opening Temperature — Engineered to open and close at the precise coolant temperature the LS300 engine requires, preventing over-cooling and overheating.
- Direct-Fit Replacement — Matches the original thermostat housing seat and coolant port dimensions of the LS300, dropping straight into place during a standard service interval.
- LS300 Concrete Pump Fitment — Confirmed compatibility with the Multiquip LS300 hydraulic-driven concrete pump series.
- Engine Temperature Stability — A properly functioning thermostat keeps the engine in its optimal thermal window, protecting the hydraulic system and pump components from heat-related stress.
- Fuel Efficiency Protection — An engine that reaches and holds correct operating temperature runs more efficiently; a failed thermostat causes the engine to run cold, increasing fuel consumption and accelerating cylinder wear.
The thermostat is the primary control valve in the engine's cooling circuit. It stays closed when the engine is cold, allowing coolant to circulate only within the engine block to build heat quickly, then opens progressively as the coolant reaches operating temperature to route flow through the radiator. On a concrete pump like the LS300, where the engine is working hard to drive the hydraulic system, a thermostat that sticks open will prevent the engine from ever reaching full operating temperature, while one that sticks closed will cause rapid overheating and potential engine damage. Replacing a worn or failed thermostat with the correct Multiquip 200438 restores proper thermal management and protects the entire drivetrain.
