The Multiquip V471788 Thermostat Upper Sealing Ring is a genuine OEM component designed for the DCA-220SSVU, DCA220SSVU-50HZ, and DCA220SSVU-60HZ super-silent diesel generator series. Sourced directly from Multiquip, this sealing ring delivers the exact material grade and compression fit required to maintain a leak-free thermostat housing on these units. Correct fitment is confirmed across both 50Hz and 60Hz variants of the DCA220SSVU platform, so you can order with confidence.
Key Features
- OEM-Grade Sealing Material — Manufactured to the precise compression and heat-resistance spec required at the thermostat upper seat, ensuring a consistent, pressure-tight seal in diesel cooling system conditions.
- Drop-In Thermostat Housing Fit — Seats directly into the thermostat upper housing on DCA220SSVU generators with no trimming or adaptation, matching the original profile exactly.
- Confirmed Fitment — DCA220SSVU Series — Compatible with DCA-220SSVU, DCA220SSVU-50HZ, and DCA220SSVU-60HZ super-silent diesel generator models.
- Prevents Coolant Bypass and Overheating — A failed or degraded sealing ring allows coolant to bypass the thermostat circuit, causing erratic temperature regulation and potential engine overtemperature events; this genuine replacement restores proper coolant flow control.
- Fuel and Coolant System Safety — Maintaining an intact thermostat seal is critical to keeping the cooling circuit pressurized correctly, protecting the engine from thermal damage during extended generator run cycles.
The thermostat upper sealing ring forms a critical pressure barrier between the thermostat housing and the engine cooling circuit. It prevents coolant from escaping around the thermostat seat, ensuring that coolant flow is properly directed through the radiator when the engine reaches operating temperature. When this ring deteriorates or loses its compression seal, coolant can leak externally or bypass the thermostat entirely, leading to inconsistent engine temperatures, visible coolant loss, and accelerated engine wear if left unaddressed.
