Put in new ET last night, I think it's a Myele. New one made October 2010. Old one made sometime in 2007. Also put in new ET cap, MTC aluminum thermostat and fan switch sensor from ECS Tuning refresh kit, new upper and lower radiator hoses, new hose from ET to water pipe, and two new power steering hoses. I re-used my old coolant level sensor but am now thinking it might not be working because when I push the ET float all the way down and hold it there with a screwdriver, I don't get any coolant level warning lights.
Didn't change my water pump because supposedly last cooling system refresh put in an EMP Stewart pump. So I will be selling a new, unused Geba water pump.
The two coolant hoses I didn't change (and probably are originals) are the ones to the heater.
