Just a brief note for those on the west side of the Atlantic - I swapped my heater valve recently and found that it was time to replace the hoses between the block, valve and heater core. Not wanting to wait for a package, I went to my local NAPA store and came home with a couple of hoses that might work. Sure enough, this hose cut into three pieces does the job to replace the set.

Just an FYI if you find yourself in a pinch.
