The Wacker Neuson Radiator Cap Mg is a genuine OEM component designed for the G100, G120, G150, G180, and G240 series mobile and skid-mounted generators. As a direct factory-sourced part, it meets the exact pressure and sealing specifications set by Wacker Neuson for these cooling systems. This cap fits a wide range of configurations across the G-series lineup, including standard, cold weather, custom, and Transport Canada variants. If you're servicing a G-series generator and need a verified replacement, part number is the correct OEM choice.
Key Features
- OEM Pressure Rating Match — Sourced directly from Wacker Neuson, this cap is engineered to the correct pressure relief threshold for the G-series cooling system, ensuring the radiator operates within its designed pressure range.
- Direct-Fit Installation — Designed to seat and seal on the radiator filler neck exactly as the original, with no modification to the cap or neck required for proper installation.
- Broad G-Series Coverage — Fits G70, G100, G120, G150, G180, and G240 mobile and skid-mounted generators across standard, cold weather, custom, and Transport Canada configurations.
- Cooling System Integrity — A correctly rated cap holds the system at optimal pressure, raising the coolant boiling point and protecting the engine from overheating — a worn or wrong-rated cap can cause coolant loss and thermal damage.
- Verified OEM Part Number — Cross-referenced to Wacker Neuson part number 5000183885 so you can order with confidence that this is the correct replacement for your machine.
A radiator cap does more than seal the cooling system — it acts as a pressure valve, maintaining the correct operating pressure inside the radiator and coolant reservoir. By keeping the system pressurized, it raises the boiling point of the coolant, allowing the engine to run at optimal temperature without losing fluid. When a radiator cap loses its seal or its pressure valve weakens, the cooling system can lose coolant, cause overheating, or allow air pockets to form — all of which accelerate engine wear on a working generator.
