Spectra Premium Radiator P/N:2001-1721P
Spectra Premium 2001-1775P front radiator for the 2018-2027 Freightliner Cascadia and other vehicles removes heat from engine coolant as it flows through the core. This Spectra Premium radiator is a heavy duty unit built to meet or exceed the performance of the original equipment it replaces, across all components, including engine and transmission.
Coolant stains around the tanks or core, a coolant level that keeps dropping or an engine that runs hot can mean this radiator is worn. A thermostat or water pump can also be behind a hot-running engine, so trace the cause before you replace the radiator.
This is a 2018-2027 Freightliner Cascadia radiator replacement, and it also fits the 2022-2026 Western Star 49X 6-cylinder 14.8L or 15.6L and the 2023-2026 49X 6-cylinder 12.8L, plus the 2022-2026 Freightliner 114SD 6-cylinder 7.7L or 12.8L. The 2018-2027 Freightliner Cascadia takes one radiator.
