I have found are you water leakage from the connection part of the engine block and water pump.
Remove, if disassembled, O-ring was off.
Without repair the broken part, it had been cheated by injecting water leak repair agent.
I have replaced all the O-ring that comes with the water pump.
When you remove the equipment around water pump 456GT (also 550/575/612) of the engine, it is possible to remove while not remove the timing belt. It's a great design. I love FR-V12.
