Chosen Solution
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 ?
In the case of a Prius I wouldn’t change the thermostat unless the car was overheating. Preventative maintenance is a good thing but in this case I would pass . The thermostat is hard to get to and requires a few hours of labor to replace. As for your statement “Thermostats can’t last forever” no not forever but I know of a few vehicles with over 300000 mile that have never had theres changed . The dealer is probably being honest here . Most dealership look for ways to ding you . I would be thankful they didn’t say they changed it when they hadn’t and then charged you for it . Hope this helps
