I've a 2005 model Chevrolet Malibu showing error codes P0128 and P0826. It has a 3.5L engine. I know little about cars, Please help me find out what is going on and how to fix it. Thanks in advance for helping me out!

 

p0128 sets when the coolant does not reach operating temp in a predetermined amount of time. Usually, replacing the thermostat fixes the problem.


here is a link for the p0826
