Product Details

CSF 2598 is a radiator designed around the original equipment style used on Acura TL models from 1996 through 1998. The aluminum core helps transfer heat efficiently, while the plastic tank construction follows the factory-style layout for a straightforward replacement. CSF manufactures a wide range of radiators and validates cooling performance through lab testing, with production backed by ISO/TSO-certified factories.

This part cross-references APDI 8012031 for the same application. If you are replacing a worn Acura TL radiator, CSF 2598 provides the correct down-flow configuration, inlet and outlet sizing, and OE-style tank/core construction for the listed vehicles.

Common Cooling Problems It Can Address

  • Coolant leaks from aged radiator tanks or seams
  • Restricted cooling performance from a clogged or corroded core
  • Overheating caused by reduced heat transfer efficiency
  • Cracked or brittle factory-style plastic tanks
  • Fitment issues when replacing a damaged OE radiator on Acura TL models

Installation Notes and Tips

Verify the inlet and outlet locations before installation, since this radiator uses a left-side inlet and right-side outlet layout. Confirm the vehicle uses the listed OE-style design and Micro, 16 psi cap requirement noted for the application. Inspect hoses, clamps, and the cooling system for wear before installing the new radiator to help prevent repeat failures.

Quality Assurance

CSF radiators are manufactured in certified facilities and built to performance-focused standards. The brand states that its radiators are wind tunnel tested for cooling validation and supplied across a broad range of vehicle applications, including Acura TL coverage for 1996-1998.
