Multiquip C3924200324 Radiator and Inter-Cooler Assembly

The Multiquip C3924200324 Radiator and Inter-Cooler Assembly is a genuine OEM component designed for DCA400SSI4F series Super-Silent diesel generators, including the DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B configurations. As a direct OEM replacement, this assembly ensures correct fitment and full compatibility across the DCA400SSI4F generator family without additional modification. Sourced directly from Multiquip, part C3924200324 meets the same engineering standards as the original unit installed at the factory. DHS Equipment stocks this part to keep your generator cooling system operating at full capacity when it counts.

Key Features

• Genuine OEM Cooling Assembly — Manufactured to the exact material and construction specifications of the original, ensuring correct coolant flow rates and inter-cooler thermal performance for the DCA400SSI4F platform.
• Combined Radiator and Inter-Cooler Unit — Integrates both the engine coolant radiator and the charge air inter-cooler into a single bolt-on assembly, matching the original mounting configuration for a straightforward installation.
• Confirmed Fitment for DCA400SSI4F Series — Verified for DCA400SSI4F, DCA400SSI4F3, DCA400SSI4F3PB, DCA400SSI4F3PD, and DCA400SSI4F3B Super-Silent generator models.
• Protects Engine from Thermal Overload — A functioning radiator and inter-cooler assembly maintains safe operating temperatures under sustained load; a degraded unit risks overheating, power de-rating, and unplanned shutdowns.
• Critical for Continuous-Duty Generator Operation — Super-Silent generators are frequently run at sustained output for extended periods; maintaining a correctly performing cooling assembly is essential to protecting the diesel engine and alternator from heat-related damage.

The radiator in this assembly draws heat out of the engine coolant to prevent the diesel engine from overheating during operation. The inter-cooler — also known as a charge air cooler — reduces the temperature of compressed intake air delivered by the turbocharger, which increases air density and allows the engine to produce rated power output efficiently. When either component is compromised by leaks, blockage, or physical damage, the engine is exposed to elevated thermal stress that can lead to loss of power, increased fuel consumption, automatic shutdown, or long-term engine damage. Replacing the assembly with a genuine OEM unit restores the original thermal management performance the generator was engineered to deliver.
