Hello Odyssey fans,

I found a pretty straight-forward and eloquent walk-through for replacing the radiator on a '97 Odyssey that I'd like to share with you folks Here is the guide to radiator replacement on the first-gen Odyssey:


1) Drain the coolant into a sealable container by loosening the radiator drain plug.

2) Remove the upper and lower radiator hoses.

3) If equipped with an automatic transaxle, place a separate sealable drain container under the transaxle Automatic Transmission Fluid (ATF) cooling lines and disconnect, drain and plug the lines and radiator fittings.

4) Detach the electrical connectors for the radiator cooling fans.

5) Remove the two upper radiator support brackets and cushion assemblies.

6) Carefully lift the radiator upward and away from the vehicle.

7) Remove the fasteners that secure the cooling fans to the radiator.

-Installation-


1) Install the radiator in the reverse order of disassembly.

2) Once installed, on Odyssey models, open the bleed valve on the thermostat housing 1/2 a turn.

3) Set the heater to the full hot position.

4) Fill the cooling system with a 50/50 mixture of a suitable coolant and water and bleed the air out of the system as necessary. Alternately squeeze the upper and lower radiator hoses to help force out any trapped air pockets. Close the bleed valve once a steady stream of coolant is visible.

Note: When mixing a 50/50 solution of coolant and water, using distilled water instead of regular tap water may help prevent the cooling system from internal deposit build-up.

5) With the radiator cap partially installed, start the engine, and allow the engine to run until the cooling fan runs two times. Turn the engine off and top up the cooling system and overflow reservoir as necessary.

6) Close the radiator cap, restart the engine and check for leaks.
