Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compression and heat-resistance characteristics required at the thermostat housing of the SA6D125E-2 engine, preventing coolant seepage under operating temperatures.
- Direct Housing Match — Dimensioned to seat flush against the thermostat housing bore on DCA220SSK units, requiring no trimming or shimming during installation.
- Confirmed Fitment — Validated for the DCA220SSK ultra-silent generator platform running the SA6D125E-2 engine; cross-reference part number 6150226490 before ordering.
- Coolant System Integrity — A correctly seated thermostat gasket maintains a leak-free seal that allows the engine's thermostat to regulate coolant flow accurately, supporting stable operating temperature and preventing overheating.
- Genuine Multiquip OEM Part — Supplied as original equipment, not a generic substitute, so material grade and gasket geometry match what left the factory.
The thermostat gasket forms the sealing interface between the thermostat housing and the engine block or coolant passage on the SA6D125E-2 diesel engine. Its job is to contain coolant under pressure at that joint, preventing external leaks while allowing the thermostat to open and close freely in response to engine temperature. When this gasket deteriorates — through heat cycling, compression set, or improper installation — coolant can escape at the housing, causing the engine to run hotter than intended and potentially leading to overheating that interrupts generator output or damages internal engine components.
