Okay, so I have a 2001 Eclipse GS 5-Speed. Noticed that the radiator was cracked so I bought myself a new radiator, new thermostat, and a flush kit. So yesterday, I took the old radiator and thermostat out and put the new ones in and flushed the system. Started putting new Antifreeze in, waited for the thermostat to open and put the radiator cap back on. Well, everything seemed to be going fine until today when I noticed that my car is now overheating at idle. There aren't any leaks so I kinda ruled out the water pump, I doubt it's my head gasket because there aren't any other signs for that, so do I just have more air in the system? Both fans ARE coming on, no leaks, and a little revving will lower the temperature again. Any thoughts? Thanks, guys.

That sounds exactly like air in the system. Did you rev it with the radiator cap off to purge air from the system? If you did not you should notice the coolant level drop after running/driving for a while. Just keep it topped off and an eye on the temp guage.

yes you may have an air pocket and it still needs to bleed out...but just because the water pump isnt leaking doesnt mean the fins arent rotted away and/or not working...if you can get it to bleed and it still overheats and you have ruled out any other causes...you may need to pull the water pump
