I replaced the coolant, thermostat, both radiator hoses and 3 small bypass hoses that go around the air filter housing.

Procedure: Opened radiator cap when engine cooled off. Opened the drain plastic bolt on the lower left side of the radiator.
Removed the air box. Replaced the small hoses (bought from honda parts online). Replaced radiator hoses. Took two bolts holding the thermostat housing. Inserted new thermostat with gasket. I used OEM so it was a straight fit.

Turned the heater to high inside the cabin. Filled the radiator to the top (installed an attachable funnel to keep the level above radiator filler neck).
Started the engine and let it idle until thermostat opened up (you can hear the radiator fan turn on). Revved the engine several times and shut it down. Installed a new radiator cap. Test drove and checked for leaks.

All the hoses were in good shape after 6 yrs and 60K miles.

On my 2012 I will wait until 75-100K before replacing hoses and thermostat and at least at 7 yrs old.
