One Stop Solutions 2402 Radiator

Radiator for Subaru Forester and Impreza

One Stop Solutions Part Number 2402 is an OSC Premium New Automotive Radiator built to match original equipment form and function. It is engineered for the 1998-2002 Subaru Forester and 1998-2001 Subaru Impreza with a downflow layout, plastic tanks, and a single-row aluminum core for direct replacement service.

Key Features

• Fits 1998-2002 Subaru Forester and 1998-2001 Subaru Impreza
• Downflow radiator design with 1 1/2 in. inlet and outlet diameters
• Aluminum core with plastic tanks
• Transmission oil cooler included with concentric cooler design
• Core dimensions: 13 3/8 in. height, 27 3/16 in. width, 5/8 in. thickness
• Pressure tested during production for leak verification
• Factory-style fitment with matched header dimensions and OE-style mounting geometry

Detailed Description

Part 2402 is designed for Subaru cooling system replacement where OE-style fit, function, and cooling performance are required. OSC uses premium-grade aluminum construction with cadmium-plated tubes inside and out to help resist premature failure, along with a die-cut gasket for sealing integrity. The radiator is individually pressure tested and built with enhancements such as improved fin density and reinforced cooling capacity to address heat load in higher-mileage vehicles. This radiator is a direct-fit choice for Subaru Forester and Subaru Impreza applications that use a downflow configuration and integrated transmission oil cooling.

This part cross-references Spectra Premium CU2152 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 when the cooler circuit is failing
• Corrosion-related radiator deterioration in older Subaru cooling systems
• Poor sealing at the radiator core or header area

Installation Notes and Tips

Verify the vehicle uses a downflow radiator with matching inlet and outlet sizes before installation. Inspect hoses, clamps, and coolant condition during replacement, and confirm the transmission cooler line connections align with the existing setup. Part 2402 is built for direct replacement service on compatible Subaru Forester and Subaru Impreza models, so factory-style fitment should be checked against the original radiator before final assembly.

Quality Assurance

OSC radiators are produced with OE-style engineering and are tested multiple times during manufacturing, including cooler testing before tank installation, core testing before assembly, and a final assembled-unit pressure test. The design also incorporates updates aimed at improving durability and cooling performance over the original radiator design.
