The Multiquip 9137168042 Thermostat Housing is a genuine OEM component designed for DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator models. Sourced directly from Multiquip, this part meets the original design and material specifications for these generator cooling systems. Verified fitment across the DCA25SSI series means straightforward installation without guesswork. DHS Equipment supplies this part backed by Multiquip's OEM sourcing, ensuring you receive the correct housing for your machine.

Key Features

• OEM Cooling System Integrity — Manufactured to the original housing geometry and material spec, maintaining proper coolant flow routing and thermostat seating within the engine cooling circuit.
• Direct-Mount Replacement — Matches the original bolt pattern and port dimensions on DCA25SSI-series generators for a bolt-on installation using existing hardware.
• Broad DCA25SSI Series Fitment — Compatible with DCA25SSIU, DCA25SSI, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generator models.
• Protects Engine Temperature Regulation — A properly seated housing keeps the thermostat correctly positioned; a cracked or warped housing allows coolant to bypass the thermostat, leading to engine overheating or overcooling and costly engine damage.
• Coolant System Sealing — Precision-formed mating surfaces support a reliable gasket seal, preventing coolant leaks that can compromise generator output and engine longevity.

The thermostat housing is a structural coolant-system component that encloses the thermostat and directs engine coolant between the engine block and the radiator. When the engine is cold, the thermostat stays closed and the housing routes coolant in a short loop to help the engine reach operating temperature quickly. Once the engine warms up, the thermostat opens and the housing channels coolant out to the radiator for heat dissipation. A damaged or leaking thermostat housing disrupts this cycle, causing coolant loss, unstable engine temperatures, and — if left unaddressed — engine overheating that can result in significant internal damage to the generator's diesel powerplant.
