Hello, I keep checking my resivor tank every week and keeps getting empty every week and i keep filling it up. There is no leaks at all. I ran a good check engine scanner on my car and the engine coolant temperature was reading 205 is that right? Where is the coolant going i cant figure this out. Thanks

There must be a leak somewhere resulting in the loss of coolant. Get a pressure test to confirm.

Some leaks are minimal, which is consistent with what you described, and would not be noticeable without any pressure test.

I have worked on many Honda's Not an expert by any means but

I would venture to guess that your head gasket is blown. These cars are famous for having blown head gaskets and I have replaced many. Most at 200k miles or above. (One at 110k) Open radiator fill to top and look for bubbles. Compression leaking into water jacket and forcing out coolant. Changed my 4th one last week.

Pressure test would help.

If the head gasket is blown, the recovery tank would not deplete. In fact it would tend to overflow. Only system leaks would lead to the recovery tank depleting. Most common leaking areas would be hose joints.
