The Multiquip 0602011079 Radiator Cap is a genuine OEM component designed for DLW and DAC series diesel light welders and diesel alternator generators. As a direct OEM replacement, this cap is built to the same pressure and sealing specifications as the original, ensuring the cooling system operates exactly as engineered. It is confirmed to fit a broad range of Multiquip equipment including DLW300ES, DLW400ES, DLW330X2, DLW400ESA4, DLW500ESA4, DAC7000SS, DAC7000SSA, DAC7000SSW, DA7000SSA2, DA7000SSA2GH, GBX12S, GBX12SK, GBX24B, GBX24BK, and GBX24S models. Sourcing the correct OEM cap by part number 0602011079 ensures a proper seal and protects your cooling system investment.
Key Features
- Correct Pressure Rating: — Matched to the OEM pressure specification for these cooling systems, maintaining proper coolant pressurization and preventing premature boil-over.
- Genuine OEM Sealing: — Cap gasket and valve materials meet original equipment standards, delivering a leak-free seal at the radiator filler neck.
- Broad Multiquip Fitment: — Covers DLW300ES, DLW400ES, DAC7000SS, DA7000SSA2, GBX12S, GBX24B series and additional models — one part number across multiple Multiquip product lines.
- Drop-In Fitment: — Designed to seat and lock onto the OEM radiator filler neck without modification, making replacement quick and straightforward in the field.
- Cooling System Protection: — A correctly functioning radiator cap holds system pressure and allows controlled coolant release; a failed or weak cap leads to coolant loss, overheating, and engine damage.
- Pressure Relief Safety: — The integrated pressure-relief valve releases excess pressure at the correct threshold, protecting hoses, the radiator, and the engine from overpressure damage.
The radiator cap serves as the pressure regulator for the engine cooling system. It seals the radiator filler neck and maintains a set pressure level within the coolant circuit, which raises the boiling point of the coolant and keeps the system operating efficiently across heavy-duty cycles. When a radiator cap weakens or fails, it can no longer hold proper pressure — causing the coolant to boil at a lower temperature, leading to overheating, coolant loss, and potential engine damage. Replacing a worn cap with the correct OEM part is one of the simplest and most cost-effective steps in cooling system maintenance.
