Basically: when they are faulty.
The original Thermostat on your Trail Blazer should last longer than the warranty, so 60,000 miles or more.
Then the fun starts.
- There are poor quality cheap Thermostats out there that tend to not last long
- If the cooling system is not maintained well and the car runs hot due to problems other than the thermostat the thermostat will fail immediately.
- If the wrong temperature rating is used the part will fail or not operate correctly
- A cooling fan that is broken or not running correctly.
