The Multiquip RE527018 Thermostat is a genuine OEM thermostat designed for the DCA220SSJ and DCA220SSJU ultra-silent diesel generators. As a direct OEM replacement, this thermostat meets the original engineering specifications set for these machines, ensuring the cooling system operates exactly as intended. Sourced directly through Multiquip's authorized parts network, the RE527018 is the correct part for DCA220SSJ and DCA220SSJU service and maintenance.
Key Features
- Genuine OEM Cooling Precision — Manufactured to the exact opening temperature and flow rating specified for the DCA220SSJ and DCA220SSJU engine cooling circuit, not a generic approximation.
- Direct Drop-In Replacement — Matches the original thermostat housing seat dimensions and connection interface, so installation follows the standard service procedure without modification.
- Confirmed Fitment — Verified for DCA220SSJ and DCA220SSJU ultra-silent diesel generators in the Multiquip DCA series.
- Protects Engine Operating Temperature — A properly functioning thermostat keeps the engine within its optimal temperature band, protecting against both overheating and inefficient cold running that accelerates wear.
- Fuel System and Engine Safety — Correct coolant temperature regulation directly supports safe combustion conditions and protects downstream components including the fuel system and exhaust on diesel generator sets.
A thermostat regulates the flow of coolant through the engine's cooling system by remaining closed during warm-up to help the engine reach operating temperature quickly, then opening to allow coolant to circulate through the radiator once the correct temperature is reached. On a diesel generator like the DCA220SSJ, maintaining precise temperature control is critical — an engine running too hot risks serious damage, while one that runs too cool burns fuel inefficiently and produces harmful deposits. When the thermostat fails or sticks, the engine loses that regulation, making prompt replacement with the correct OEM part essential to keeping the generator running properly.
