The Wacker Neuson Thermostat is a genuine OEM thermostat designed for the G100 and G120 mobile generator series, including skid-mounted, cold weather, and custom configurations. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, this thermostat meets the exact specifications of the original component — no guesswork on compatibility. It fits an extensive range of G100 and G120 generator variants, including Tier 3 models, Transport Canada-compliant units, and switchable 600-volt configurations, making it the right choice for fleet operators and service technicians working across multiple generator builds.
Key Features
- Calibrated Opening Temperature: — Built to the OEM-specified activation point, ensuring coolant flow begins and ends at the correct engine temperature — not too early, not too late.
- Drop-In OEM Fitment: — Matches the original housing bore, flange dimensions, and seal interface of the G100 and G120 engine cooling system for a straightforward installation.
- Broad Generator Series Coverage: — Compatible with G70, G100, and G120 mobile generator variants including standard, cold weather, skid-mounted, custom, and Tier 3 configurations.
- Engine Temperature Stability: — A functioning thermostat keeps the engine in its optimal operating range; a failed one causes overheating or chronic under-temperature running, both of which accelerate engine wear and increase fuel consumption.
- Genuine OEM Part: — Supplied directly from Wacker Neuson, part number 5000217830, so you're receiving the same component built into these generators at the factory.
A thermostat regulates engine coolant temperature by blocking or opening the flow of coolant to the radiator depending on how hot the engine is running. When the engine is cold, the thermostat stays closed to help it reach operating temperature quickly; once the target temperature is reached, it opens to allow the radiator to dissipate heat. A failed thermostat — whether stuck open or stuck closed — causes the engine to run either too cool for efficient combustion or too hot for safe continuous operation, both of which can lead to premature wear, poor power output, and potential engine damage on a working generator.
