These are my original T's... 2004, 209k miles, coolant changed once at 105k with factory Toyota fluid, FL/GA (southern) vehicle.
Overall in better shape than I expected. You can see the outer flange did come off on both but still felt solid with no cracks. Was getting minor seepage on the old ones. Hoses seemed fine so left those alone. Took all of 30 mins and lost maybe a cup of fluid like others said. Really not all that difficult to do. Used regular ole pliers.
Good piece of mind preventative care though
