Stinger, I changed both hoses off of the expansion tank with my coolant refresh, 4 and 5, the other hoses from the heat control valve to heater core looked like they had been changed recently, I saw some rust stains underneath the car so it confirmed a leak there at one time in the past, nothing particularly tricky, the heater core connection was easy to get to when I was doing CCV so I already had the air filter tray removed, the connection under the intake was on there pretty tight but loosened up ok once I got a hold of it. My hoses were pretty spongy and were definitely ready to be changed but I did notice most DIYs don't mention these. I chalked it up to having high mileage.
