My engine runs great. Starts up fine idles good. Sometimes when I'm driving and push in the clutch to come to a stop the idle is noticably higher then normal, but with a tap of the throttle goes right back down. Anyways I went out and dumped out some my fluid that was in my overflow can so thats good. I took it for a test drive and the temp is not going up like it used to it is very steady right around normal operating temp. I think it was the air in my heater lines and the overflow can being full. what do you think.
