I replaced my coolant at the dealership for my 2014 Toyota Prius at 50,000 miles . I asked the forum when you replace the thermostat . The answer was when the coolant was replaced , The dealer said they had never replaced a thermostat in a Prius . Their parts department said they had not ordered one either . Thermostats can't last forever . Is the dealer telling me the truth ? Advise ?
