Honda Civic Coolant Loss

I have this scheduled for Wednesday for the other Honda dealer in town to look at it. After describing the problem to a service advisor I was told all they would do is a pressure test and if that doesn't show anything then they would do a leak-down test. I wasn't familiar with a leak-down test but after looking it up I don't see how that would show coolant loss. You had mentioned a chemical test could be done to see if it was burning off. Is that something a dealer would have to do? And with the small amount of coolant I am losing would you say it's more likely a loose connection?

Thanks again for all of your help.

Hey I wanted to know if you ever found out what cause your leak on your Honda? I may have the same problem too

I never found out what was causing the leak, though it no longer leaks coolant. I've run AC/Defrost pretty regularly the last several months and there has been no drop in the coolant overflow tank level.

I tried a new radiator cap and that didn't make a difference. If you haven't already try reading the previous replies.
