But someone mentioned bleeding the system. When your car is cool open the radiator cap and turn the car on and let it run for about 15 minutes. Bubbles will mess up the cooling system.
Yea, I gotta do that when I get home. Not home right now.

Water wetter was fine during summer, but I think that it got cold and my not having antifreeze fugged everything up.
Later, off to the Honda dealership I go to pick up: thermostat, radiator cap, coolant.
Wish me luck.
