I own a 2016 Chevrolet Silverado 1500 5.3L. Just yesterday I noticed my engine temperature was at 210, a little higher than normal. Then again today with just normal driving its getting hot again. Then the check engine light came on. It has plenty on oil and antifreeze. Is this a common issue and what do I do to fix it?
Since the CEL came on the first step is to get any stored codes read, usually done for free at parts stores such as Autozone. Then post the codes here, format is P0123.
As far as the temperature, a quick search showed normal range is 195-220 degrees.
