Customer Question
My engine (2005 GMC Sierra)...
My engine (2005 GMC Sierra) was overheating, and just took it to a mechanic that says it is the thermostat. The same mechanic replaced the thermostat 13 months ago, but says because of the "weird" weather we've been having, it's not surprising. Our weather has been more hot and humid than average, but not extreme.13 months seems ridiculous for this part to fail. Any advice?

Good morning,

The thermostat was likely just faulty. The weather should have no affect on the longevity of the thermostat, especially humidity or heat. The thermostat should be capable of going from temperature extremes from below freezing to above 250 degrees with no issue at all.

I think the mechanic is just blaming the weather to avoid having to warranty the part.

Thanks for the reply. What is a typical warranty? It's been just over 12 months, so figured I'm out of luck.
GMC Mechanic: Jared D, ASE Certified Technician replied 10 months ago

Typically most shops will offer a 12 month 12k mile warranty on thermostats and such. In a case like this, personally I would probably offer to cover the labor cost if the customer covers the parts.

I live in a state where the weather is always weird. We have days where it snows in the morning and gets up in the 70s in the afternoon. Our thermostats do just fine.
