The Wacker Neuson Gasket, Thermostat is a genuine OEM component designed for the G100 and G120 series mobile generators. Sourced directly from Wacker Neuson, this gasket delivers the exact material grade, thickness, and sealing profile specified for these machines — no guesswork on fitment. It covers an extensive range of G100 and G120 configurations including skid-mounted, cold weather, custom, switchable 600-volt Tier 3, and Transport Canada variants, as well as G70 mobile generator applications. When you need the thermostat housing sealed correctly, this is the part that does it right the first time.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's specified material composition and compression profile, ensuring consistent sealing performance at the thermostat housing interface.
- Drop-In Thermostat Housing Fit — Engineered to match the exact bolt pattern and mating surface geometry of the thermostat housing on G100 and G120 engines, seating flush without trimming or reworking.
- Broad G-Series Generator Coverage — Compatible with G70, G100, and G120 mobile generator configurations including standard, cold weather, skid-mounted, switchable 600-volt Tier 3, and Transport Canada-spec units.
- Protects Coolant System Integrity — A compromised thermostat gasket allows coolant to bypass or leak at the housing, leading to erratic operating temperatures and potential engine damage; this genuine replacement restores a verified, pressure-tight seal.
- Genuine Wacker Neuson OEM Part — Carries part number 5000217831 and is supplied as an authorized OEM replacement, meaning it meets the same production standards as the original part installed at the factory.
The thermostat gasket forms a pressure-tight seal between the thermostat housing and the engine block or coolant passage, preventing coolant from leaking at the joint while the cooling system operates under pressure. It works in tandem with the thermostat itself to keep coolant where it belongs, allowing the engine to reach and hold its correct operating temperature. When this gasket deteriorates or is disturbed during service, coolant can seep past the housing, causing visible leaks, loss of coolant, and inconsistent engine temperatures that shorten engine life — making a clean, correctly spec'd replacement gasket an essential part of any thermostat service.
