Multiquip DZ113662 DEF Tank - OEM Replacement Part for WhisperWatt Super Silent Generators

The DEF (Diesel Exhaust Fluid) tank is a critical emissions system component for Multiquip WhisperWatt super silent generators equipped with John Deere turbocharged EGR diesel engines. This tank stores the diesel exhaust fluid required for the selective catalytic reduction (SCR) system that enables these Tier 4 Final compliant engines to meet stringent emissions standards.

Before initial generator start-up, the DEF tank must be completely filled with DEF fluid. During operation, never overfill the tank as DEF fluid expands when heated. For refilling during continuous operation, it is recommended to shut down the engine first. Always ensure the engine is OFF before removing the filler cap to add fluid. The tank cap must be tightened securely after each refill to maintain proper system pressure and prevent contamination.

This genuine OEM DEF tank is engineered specifically for WhisperWatt series generators and ensures reliable operation of the emissions control system. Regular monitoring of DEF levels is essential to prevent shutdown warnings and maintain uninterrupted generator performance.
