Detailed Description

One Stop Solutions 2368 is an OE-style radiator engineered for the cooling demands of select full-size GM trucks. The design follows original form and function, with factory-style fitment, a die-cut gasket for sealing, and individually pressure-tested construction. The radiator includes a transmission oil cooler and is built with premium-grade components to support durability in daily driving and higher-mileage use. This part cross-references Spectra Premium CU2334 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from an aging or damaged radiator tank or core
• Overheating caused by restricted coolant flow or reduced heat transfer
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Fitment issues from a replacement radiator that does not match OE dimensions
• Cooling system wear on high-mileage Chevrolet Silverado 1500 and GMC Sierra 1500 trucks

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and cooler line spacing before installation. This unit is a crossflow design and is listed for 1999 Chevrolet Silverado 1500, 2001-2004 Chevrolet Silverado 1500, and 1999-2004 GMC Sierra 1500 with the noted configuration. Confirm the vehicle does not require an engine oil cooler, as this radiator is listed without one. Part number 2368 should be matched to the vehicle’s cooling system layout before removal of the original radiator.

Quality Assurance

OSC radiators are built with engineering updates aimed at improving cooling performance and service life, including enhanced fin density and thicker core construction where applicable. Each radiator is pressure tested during production, and cooler circuits are tested before and after assembly to help verify sealing and function.
