Can Overheating Be Linked To Overflow Res

[scruffboy]

Yeah, I'm leaking coolant. It's not overflow res. Problem is, I leave for work, its dark, I come home, its dark and damn hard to see where problem is. Went for short drive this morning (3 Mi.) and definitely was burning off coolant, which I topped off last night. Parked under streetlamp near work, popped hood and a little mist coming from engine compartment. Nothing on top though, upper hose good, but thought I saw moisture on lower hoses. Question, if I have pressure test done to check system could it do more harm then good? I didn't even think to check tailpipe, but I checked oil level in dark, not over full, but could not tell color. Should I bring it to a shop? How will I know they ain't jerkin me around if they tell me its something serious and its only a hose?

Thanks,
