2001 Chevrolet Impala - Thermostats die every year

Has anyone had to replace their thermostat several times? Like once a year?

Are you doing the work yourself or are you taking it to a mechanic? If you’re really blowing through thermostats that quickly, I would think there is another underlying issue that needs to be found and addressed

Twice with the same mechanic. Then another mechanic recently replaced radiator, hoses, thermostat. (when radiator went bad).
A month later thermostat stopped working (stuck on cold) . Mechanic replaced thermostat (no charge). Working fine now. I know both mechanics are not using GM parts, they both use chain auto store.


GM does not make parts . They have them made from many different suppliers so the thermostats may be just like the ones they had on the assembly line.
