My 2007 Honda Civic Coupe seems to only overheat in traffic. When driving on freeway it is fine. Here are the steps we've taken so far. I've read the other posts and they seem to say Thermostat.

1. Replaced Thermostat
2. Replaced Radiator
3. Replaced Fan
4. Replaced Thermostat again

Any other suggestions of what this could be? It is really getting frustrating.

Thanks

 

Are you sure the fan is working? I'd make sure it has the correct mix of fluid? Run it and bleed the system of all air and make sure the fan is cycling on and off in the driveway.

 

Yeah- checked the new fan. It is working. Not sure what else it could be- basically replaced the entire system without checking the water pump or Head Gasket. don't think it is either of those- as it only does it in Traffic.

 

Are both fans running ?

 

According to the mechanic who has been working on it, Yes.
