Check the coolant level in the radiator at the cap as it may be the low coolant warning system that is activated as the water runs away from it as you change direction. If it is serious enough the engine light will come on and the CPU will send the engine into limp home mode.
I believe what this symbol is the radiator. It comes on when the coolant level is low. Take a look at your radiator coolant level and if low add some to the full mark. Do this when the engine is cold to avoid getting burned from hot water and steam.
i think you got a head gasket leak,,,if its buring coolant the only thing that will burn it is a leaking head gasket,,its probably leaking into the cylinder and burning it and leaking externally where you see coolant on the tranny,,,replace the head gasket,,,
You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.
