I have recently had some overheating problems. Radiator was completely gunned so I had to flush it. Doing so cause some leaks I have fixed. I have cleaned it out, refilled, filled overflow to the line on the bottom, held a few times at operating temp with heat on. My gauge has no numbers just lines. It is getting north of the big line a little over the middle. Feels like it is too hot to me. Not in the red, but only like 3 or 4 ticks away. Anyone have a picture of where in the lines it should hover at operating temperature? I also see people say to top off overflow? Should I have the overflow filled over that line on the bottom?? Thanks is advance for any help.
