The thermostat is integral with a plastic housing that cracks over time. I replaced mine at 106k miles and plan to do so preemptively by the time I'm at 200k.
I did my thermostat and housing as well as all hoses and fittings at 80k when i had the front end apart on the truck from an accident. I also have a new housing and thermostat on the shelf. I'm pretty sure I'll go coils when i have deal with airstruts!
