Thanks... Well, the reason why I would recommend replacing it out of warranty (at least before 100k miles) because apparently the gasket deteriorates and chunks into the cooling system. (possibly clogging up your thermostat)

If you do a coolant change and see black chunks in the fluid, change this gasket.

btw, this gasket will not last forever, its made of rubber. Mine @ 100k was totally flat and squared into the grooves when the new gasket was diamond shaped and almost an 1/8th of an inch thicker.
