Detailed Description

OSC part number 2989 is a replacement radiator designed around original equipment dimensions and cooling layout. It uses premium-grade materials, including aluminum cooling components and cadmium-plated tubes, to help resist premature failure in demanding under-hood conditions. The integrated transmission oil cooler is built into the unit, and the radiator is assembled to factory specifications for fit and function in Honda Accord, Accord Crosstour, and Crosstour applications.

This radiator cross-references Spectra Premium CU2989 for the same application.

What It Helps Address

• Overheating caused by a restricted or leaking radiator
• Transmission fluid temperature concerns related to a failing cooler circuit
• Coolant loss from cracked tanks, worn seals, or damaged core passages
• Reduced cooling efficiency in high-mileage Honda Accord and Crosstour vehicles
• Fitment issues from non-OE-style replacement parts

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet size, and transmission cooler line spacing before installation. Transfer any vehicle-specific components required by the application and inspect hoses, clamps, and coolant condition while the cooling system is open. After installation, refill with the correct coolant, bleed air from the system, and confirm there are no leaks at the cooler fittings or tank seams.

Quality Assurance

OSC states that each radiator is individually pressure tested, with cooler circuits checked before tank installation and the completed assembly tested again. The design also incorporates enhancements aimed at improving durability and cooling performance in vehicles that have accumulated higher mileage.
