Hi! I was wondering if anybody has an idea on what the problem is on my 2000 Civic Si. When the car sits idling for a few minutes, it starts to overheat! This also happens whenever a lot of heavy stop and go type traffic is happening. This is the only time this happens! Can anyone help? Thank you!

 

you check if you have any coolant? you might have air in your system, same thing happened to my buddy's gsr yesterday night, he had air in his system. car overheated like a **** and idle'd like ****!
