QuiksilverH22

Hi honda-tech, Just recently my civic has been overheating in traffic at idle but a little throttle has been keeping it at normal temps. But now it's overheating as I'm driving and when I give it gas. I've switched radiators recently but it was from an old civic in my backyard that had been sitting for 3 years. I havent checked the thermostat or the water pump but have noticed a leak on the bottom corner of my radiator which I think is the culprit but I havent dealt with much overheating so now I'm asking you HT to help me out on this. Please give any advice you can all will be very much appreciated.

How hot does it get when you give it gas? When it overheats under load, it's pointing towards the head gasket.

It gets almost to the H and stays there. The leak in the radiator was a loose clamp on the bottom hose and I replaced the thermostat. But it got too late ill see how it goes in the morning.

Did the overheating start before or after you swapped radiators?
