There is a small passage way around the thermo that should let water out the tele tale to give you indication that the there is water going through the block. The only other place water could be escaping is from the P/H base gasket. Did you replace only the thermos or did you replace the housing also, that passage way could be clogged with debri.

I would not worrie about it then, your mechanic is correct. Just make sure the engine is not overheating.
