The Multiquip 0602011029 Radiator Cap is a genuine OEM component designed for DCA and MQP series diesel-powered generators, including the DCA125SSIU, DCA70SSIU2, DCA45SSIU4, DCA85USJ2, DCA150SSI, DCA150SSIU, and MQP56. As a direct OEM replacement, this cap is built to the exact pressure and sealing specifications required by these generator cooling systems. It fits the DCA125SSIU50HZ and DCA125SSIU60HZ variants as well, making it a versatile service part for fleets running multiple DCA-series units. Order with confidence knowing part number 0602011029 is the correct, authorized cap for your machine.
Key Features
- Exact Pressure Rating — Engineered to the precise pressure relief specification of the DCA and MQP series cooling systems, ensuring the system pressurizes and vents correctly.
- OEM Sealing Material — The cap's sealing surfaces match the original neck seat geometry on these generators, delivering a leak-free fit without machining or adaptation.
- Broad DCA Series Coverage — A single part number covers the DCA45SSIU4, DCA70SSIU2, DCA85USJ2, DCA125SSIU, DCA150SSI, DCA150SSIU, DCA125USI, DCA125USI3CAN, DCA125SSIU50HZ, DCA125SSIU60HZ, and MQP56.
- Cooling System Integrity — A correctly rated radiator cap maintains optimal coolant operating temperature and prevents boilover, protecting the engine during extended generator runtime.
- Direct Swap Service Part — Sized and threaded to drop onto the original radiator neck — no tools or hardware beyond basic hand tightening required for installation.
The radiator cap is a pressure-control valve for the engine cooling system. It seals the cooling circuit and maintains a set pressure level, which raises the boiling point of the coolant and keeps the engine operating within its safe thermal range. When a radiator cap wears out or loses its seal, the system can lose pressure, causing coolant to boil off prematurely, the engine to overheat, and — in a generator application — a costly unplanned shutdown on a live job. Replacing a worn cap with the correct OEM-rated unit is one of the simplest and most impactful cooling system maintenance steps available.
