Key Features
- OEM-Spec Electrical Accuracy — Manufactured to the correct switching threshold and circuit specification, so the sensor triggers at the right coolant level — not too early, not too late.
- Direct-Fit Installation — Designed as a drop-in replacement with the original connector and thread pitch, fitting the G1100 coolant system without modification to wiring or mounting points.
- Confirmed G1100 Fitment — Verified for the Wacker Neuson G1100 Generator, giving you confidence you're ordering the correct part for your machine.
- Engine Protection Where It Counts — A properly functioning low coolant switch allows the generator's protection circuit to shut the engine down before heat damage occurs — a failed switch leaves the engine exposed to serious overheating risk.
- Electrical Safety Compliance — As a genuine OEM switch, 5100029801 meets the original protection circuit requirements, ensuring the generator's coolant monitoring system operates as the manufacturer intended.
The low coolant switch monitors the coolant level in the engine's cooling system and sends a signal to the generator's protection circuit when the level drops below a safe threshold. When it detects a low-coolant condition, it triggers an automatic shutdown, protecting the engine from overheating and potential seizure. A faulty or failed switch can either allow the engine to run unprotected through a low-coolant event, or cause nuisance shutdowns by triggering incorrectly — either way, replacing a worn switch promptly is essential to keeping your generator running safely and reliably.
