The lower rad hose is connected to the thermostat housing and the thermostat is in the water pump inlet cavity, quite low on the engine.

If you replace it use only OEM part and get a new gasket - it does not come with the thermostat.

The hoses which go to the tranny contain ATF - so if the leak is coolant you know it's not there.

Water pump is a good candidate for the leak.... but that requires disassembling the timing covers and belt (and rad + fans).
