Detailed Description

This CSF radiator is designed for Jeep Wrangler cooling system service where an all-metal construction is preferred over plastic-tank designs. The copper-and-brass build supports heat transfer and durability, while the 3-row core layout provides the capacity expected in heavy-duty use. CSF 2578 also includes a 12 in. high-efficiency concentric-type oil cooler section and is configured as a multifit model for the listed Wrangler applications.

Compatible With 1987-1995 Jeep Wrangler and 1997-2004 Jeep Wrangler, this radiator is a direct-fit cooling replacement for vehicles using the specified down-flow layout and inlet/outlet locations. This part cross-references Spectra Premium CU2578 for the same application.

Common Cooling Issues This Part May Address

• Overheating during stop-and-go driving or off-road use
• Reduced cooling efficiency from a worn or leaking radiator
• Corrosion or tank failure in older cooling systems
• Oil temperature management concerns in radiator-equipped applications
• Fitment problems when replacing a damaged OE-style radiator

Installation Notes and Tips

Verify inlet and outlet orientation before installation: 1 1/4 in. right inlet and 1 1/2 in. left outlet. Confirm clearance for the removable A/C bracket where equipped, and match the existing cooling system layout to the down-flow configuration. Use the correct cap specification for the vehicle, as no cap is included.
