Detailed Description

OSC part number 2270 is a replacement radiator for the 1999-2004 Honda Odyssey that follows original equipment form and function. It uses a single-row core, plastic tanks, and a concentric transmission cooler layout to match the vehicle’s cooling system design. The radiator is built with premium materials and engineered for a direct drop-in fit on the Odyssey platform.

The core measures 17 11/16 inches high by 30 5/8 inches wide, with a 5/8-inch thickness. Inlet and outlet diameters are both 1 1/4 inches, and the unit is configured as a downflow radiator. Part number 2270 is a practical choice for Honda Odyssey cooling system service when the original radiator shows signs of age, leakage, or reduced heat transfer.

Common Problems This Radiator Can Address

  • Coolant leaks from an aging radiator tank or core
  • Overheating caused by restricted heat dissipation
  • Transmission fluid temperature concerns tied to a failing cooler circuit
  • Cracked or weakened plastic end tanks
  • Reduced cooling efficiency in high-mileage Honda Odyssey models

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and cooler line layout before installation on your 1999-2004 Honda Odyssey. Inspect hoses, clamps, and cooler connections for wear during replacement, and confirm the cooling system is properly flushed and refilled after installation. Part number 2270 is designed for factory-style placement, which helps streamline the replacement process.

Quality Assurance

OSC radiators are individually pressure tested during production, with the transmission and engine oil cooler circuits checked before assembly and the completed radiator tested again. The design uses enhanced cooling features and factory-spec component placement to support durability and consistent operation in the Honda Odyssey application.
