I just replaced mine. One fell apart as soon as my hand touched it, and I had to fish bits out of all 3 hoses. The other must have been replaced before, it looked to be in pretty good shape (but didn't look new).
However, the new ones are noticeably smaller than the old ones, and with reusing the OEM clamps it's leaking like crazy. Not dripping or spurting, but a steady stream of coolant.
I have some towing to do tomorrow, and am leaving town this weekend, so I'm just going to get some worm gear clamps at whatever store is still open and tighten the crap out of them.
