The Wacker Neuson Heater Hose 5/8 X 55 is a genuine OEM component designed for G100 and G120 series mobile generators. As a factory-sourced part, is built to the exact dimensions and material standards required for proper coolant routing and cold-weather heating system performance on these machines. This hose is confirmed to fit an extensive range of G100 and G120 configurations, including standard, cold weather, custom, and Tier 3 variants across multiple production runs. Having the correct hose in place ensures your generator's heating circuit operates as intended in demanding job conditions.
Key Features
- OEM-Spec Hose Construction — Manufactured to the exact inner diameter and length specification (5/8 in. x 55 in.) required for proper flow and sealing in the heater circuit — no trimming or adapting needed.
- Direct-Connection Fit — Routes and connects exactly as the original, mating correctly with factory fittings on G100 and G120 generator heater systems for a clean, secure installation.
- Broad G100 and G120 Coverage — Fits a wide range of configurations including standard, cold weather, custom, Tier 3, Canada Transport, and 600-volt switchable variants of both generator families.
- Cold-Weather System Integrity — A worn or cracked heater hose can cause coolant loss and heating system failure in cold-weather-equipped generators, compromising engine warm-up and cold-start protection.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this part carries the OEM part number 5000179791 and is backed by the confidence of genuine manufacturer quality for a critical fluid-carrying component.
The heater hose routes heated coolant from the engine to the generator's cab or cold-weather heating system, maintaining the operating temperature needed for reliable cold-climate starts and continuous operation in low-temperature environments. On cold-weather-equipped G100 and G120 generators, this circuit is essential — a failed or leaking hose can cause the heating system to lose pressure and effectiveness, leaving the engine and electrical components vulnerable to the cold. Replacing a degraded hose with the correct OEM part restores the circuit to full function and prevents coolant loss that could lead to broader engine damage.
