Detailed Description

OSC part number 19 is a replacement radiator engineered to match OE form and function for select Honda Accord and Honda Prelude models. It uses a downflow layout with a plastic tank construction and a PA core, along with a concentric transmission oil cooler where originally equipped. The radiator is built with cadmium-plated tubes and a die-cut gasket to help reduce leak risk and improve durability in service. This unit is also designed as a multi-fit replacement without changing the original look or fit of the cooling system.

This part cross-references Spectra Premium CU19 for the same application.

What It Helps Address

• Overheating caused by a restricted or leaking radiator
• Transmission fluid temperature concerns tied to a failing cooler circuit
• Coolant loss from cracked tanks, worn seals, or damaged core joints
• Reduced cooling efficiency in high-mileage Honda Accord and Honda Prelude vehicles
• Fitment issues from aging original equipment radiators

Installation Notes and Tips

Verify inlet and outlet sizes, core dimensions, and cooler configuration before installation. This radiator is built for direct replacement use in 1990-1993 Honda Accord and 1992-1996 Honda Prelude applications, so matching the original cooling system layout is important. Inspect hoses, clamps, and surrounding cooling components during replacement to help prevent repeat failures. Part number 19 is supplied as a radiator assembly only; cap included is not listed.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again after assembly. Transmission and engine oil cooler circuits are checked prior to installation into the tank, and each radiator is pressure tested during production to help confirm sealing and performance.
