Detailed Description

This OSC radiator is engineered for the 2000 Mitsubishi Eclipse and built to match original cooling-system layout and performance expectations. The unit uses premium-grade aluminum construction with plastic tanks, a single-row core, and a concentric transmission cooler to support proper heat transfer in automatic-transmission applications. The radiator is designed around OE dimensions, including a 29 1/8 in. inlet and outlet header length, to help maintain correct fit and alignment in the engine bay. Part number 2405 is a practical replacement choice when the original radiator shows signs of leakage, reduced cooling efficiency, or transmission cooler wear.

This part cross-references Spectra Premium CU2410 for the same application.

Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature concerns related to a worn cooler circuit
• Corrosion or internal wear in the original radiator core
• Fitment issues after replacing a damaged factory radiator

Installation Notes and Tips

Verify inlet and outlet hose sizes, cooler line routing, and mounting points before installation. This radiator is a downflow design and should be matched to the vehicle’s original cooling configuration. Inspect hoses, clamps, and related cooling components during replacement to help prevent repeat failures. Confirm automatic-transmission cooler connections are clean and properly seated before returning the vehicle to service.

Quality Assurance

OSC radiators are built to OE-style specifications and individually pressure tested during production. The design uses premium materials and factory-style component placement to support consistent cooling performance and long service life on the 2000 Mitsubishi Eclipse.
