Re: Radiator Low in \'84 CJ7 258

When you replaced the Rad cap, did you replace the soft rubber line that runs from the Rad to the overflow bottle. If that line is old, it may be cracked in places. When the fluid cools down and sucks on that tube, if it has cracks the Rad will suck only air, and not the fluid out of the overflow bottle. even if you can not see visable cracks in the line, if it is old, replace it. All it would take to cause a problem like you descrive would be a couple of pin holes.
