The Wacker Neuson Coolant Sensor Wiring Harness is a genuine OEM component designed for the G100, G120, G150, G180, and G240 series mobile generators. As a direct OEM part, it is manufactured to the exact electrical specifications required by Wacker Neuson generator systems, ensuring the coolant sensor communicates correctly with the machine's monitoring and protection circuits. This harness fits an extensive range of G-series configurations including standard mobile, cold weather, custom, skid-mounted, and Transport Canada variants across Tier 3 engine platforms.

Key Features

  • OEM-Spec Wiring Integrity — Manufactured with correct conductor gauge, connector pinout, and insulation rating to match the original harness specifications for Wacker Neuson G-series generators.
  • Plug-and-Play Connector Fit — Designed to connect directly to the coolant sensor and control harness using the factory connector housings, eliminating any need for splicing or adapter wiring.
  • Broad G-Series Compatibility — Verified fitment across G100, G120, G150, G180, and G240 mobile generator models in standard, cold weather, custom, skid, and Transport Canada configurations.
  • Protects Engine Against Overheating — A functioning harness ensures the coolant temperature sensor signal reaches the generator's control system accurately; a failed harness can cause false shutdowns or, worse, prevent overtemperature protection from activating.
  • Electrical Safety Compliance — As a genuine OEM harness, the wiring insulation and connector materials meet the original design standards for the generator's electrical protection system, supporting safe and compliant operation.

The coolant sensor wiring harness carries the temperature signal from the engine's coolant sensor to the generator's control and protection system. This signal allows the machine to monitor engine operating temperature in real time and trigger a shutdown if overheating is detected — a critical safeguard that prevents serious engine damage. When the harness is damaged, corroded, or broken, the sensor signal can be lost or corrupted, leaving the generator either unable to start correctly or, in a worst-case scenario, running without effective thermal protection.
