Hello,

I have had an engine overheating issue in my 2005 Honda Civic for more than 2 years now. Basically during the summer months when it's hot (more than 80F), driving the car at slower speeds or stop and go traffic leads to engine overheating.

I finally got around to fixing it a few weeks back by replacing the thermostat. Noticed that the old thermostat gasket was not in shape and replaced it as well. I also bled the coolant by running the car for about 10mins with the radiator cap open.

Thought I had fixed it because didn't see the issue come up in the past couple of weeks. But yesterday it was pretty hot and sure enough, the engine got overheated on a slow drive.

I have run out of ideas on how to further diagnose the issue. Just fyi, the radiator fans work fine and I didn't notice any obvious blockage in the radiator.

Any advice?
