Show original supplier description
The Koyorad A2806 radiator is an OE-equivalent replacement specifically engineered for 2005-2010 Honda Odyssey vehicles, including those equipped with an internal transmission oil cooler. It directly addresses issues like leaking radiator tanks, restricted coolant flow from an aging core, and overheating caused by radiator deterioration. Furthermore, it helps mitigate transmission fluid cooling concerns on equipped models. Installation notes advise verifying inlet and outlet hose sizes, cooler line connections, and mounting points before installation. It is recommended to flush the cooling system and inspect hoses, clamps, and the thermostat before fitting the new radiator. For optimal results, refill with the correct coolant mixture and bleed the system according to Honda service procedures. The Koyorad A2806 is built to OE-equivalent standards, ensuring application-specific dimensions and materials for accurate replacement. This direct-fit solution provides the correct fitment details and cooling-system connections for the specified Honda Odyssey models.
