2012 honda accord. drain and filled radiator. now know heat. need advice
Sounds like you got some air in the system, recheck your level now that the thermostat has open and closed, it is at the min line?
I agree with Tom, you probably have air trapped in the system. The easiest way to bleed it all out is to remove the radiator cap (if it has one, as this varies on many cars), start the car, let it run for quite awhile and check that you can see the water movement in the radiator opening after it warms up. Also you can set the heat to it's highest temp setting and put the fan on highest speed to further purge out any remaining air. Just don't stand too close to the car while running it hot because sometimes it will "belch" and send hot water spraying out & you can get badly burnt. If your car has no radiator cap, follow the same procedure, but leave the overflow bottle cap off instead. Let us know how you make out.
