Detailed Product Information

Part number CU2315 is a Spectra Premium radiator engineered for the same durability and performance expectations associated with original equipment cooling components. It is listed for multiple Chevrolet Silverado, Chevrolet C/K, GMC C/K, and Tahoe applications, including 1995-2000 Chevrolet C2500, C3500, K2500, K3500, and 1995-1998 Chevrolet C1500 and K1500 models with the specified cooling configuration. This radiator also covers 2001-2002 Chevrolet Silverado 2500 and 2004 Chevrolet Silverado 3500 applications with the noted equipment requirements.

Use CU2315 when replacing a leaking, clogged, or damaged radiator in a compatible Chevrolet Silverado or GMC truck cooling system. The fitment notes are important: several applications require no transmission oil cooler, no engine oil cooler, standard duty cooling, and a radiator cap.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or corroded radiator
• Overheating caused by restricted coolant flow
• Cooling performance loss from internal blockage or age-related wear
• Temperature instability in a worn Chevrolet Silverado or GMC truck radiator
• Replacement needs after impact damage or tank failure

Installation Notes and Tips

Verify radiator dimensions, tank spacing, and cooling equipment before ordering. For listed applications, confirm whether the vehicle uses a transmission oil cooler or engine oil cooler, since the fitment notes specify configurations without TOC and with EOC on many rows. A radiator cap is required on the noted applications, and the cooling system should be inspected for hose condition, thermostat operation, and contamination before installation.

Quality Assurance

Spectra Premium radiators are built to meet OE-style durability expectations for replacement cooling service. Part number CU2315 is supported by multiple interchange references, including APDI 8011520 and Gates 1520, which helps confirm application matching for select Chevrolet and GMC models.
