CHEVROLET BLAZER THERMOSTAT PROBLEM

1997 Chevrolet Blazer • 14,000 miles

I have a P0128, for coolant thermostat. Do I need to change the thermostat?
Also, I have a P0446. For Evap Emissions. What doe this fully mean?
Thanks.

Yes you need to change the thermostat, that is a very very common issue on those vehicles, I do atleast one a month. The p0446 signifies that you have a leak in you evaporative system and could be anything from a bad or loose fuel cap, to a broken hose to a faulty valve. You need to take it to a shop that has the specialed equipment and knowledge to diagnose that code.
