The thermostats are not listed in the parts covered in the extended 5 years/100 000 mi. warranty (with 100$ deductible) for the 6.5 engine.
Regular maintenance items are not covered. The thermostat is not listed for a regular check or replacement on my owner's manual, but it is normally considered a maintenance item.
