Why is my 2006 Suburban running hot?

Topic starter

Got a 2006 5.3L 1500 z71 Chevrolet Suburban and it seems to be running hot and when I check the coolant in the reservoir it is always very low.  There are no leaks anywhere.  My engine was replaced last summer so no more white smoke - Lol!  What could be the problem, also no codes displaying?

Have you replaced the radiator cap?

 


No, thank you for the suggestion.
